Description

Shroud implant assembly, method of manufacturing and alveolar bone reinforced implant assembly

The present invention relates to a lid-type implant assembly and a method for manufacturing the same, and more particularly, to a lid-type implant assembly and a method for manufacturing the same that can be safely and simply performed regardless of the position of the alveolar bone, bone diameter, width, and the like.

The present invention also relates to an alveolar bone-reinforced implant assembly which can be easily and safely treated by reinforcing the alveolar bone without deleting the alveolar bone and covering the alveolar bone.

Implant means the implantation of artificial artificial teeth into human alveolar bone. In other words, the dental implant is a method of restoring the function of the tooth by restoring the tooth root made of metal material such as titanium, which is not rejected to the human body to replace the lost tooth root, in the alveolar bone in the toothless tooth, and then fixing the artificial tooth. to be.

In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissue and have the same function or shape as the natural teeth and do not cause tooth decay. It is widely practiced.

The implant procedure is performed by drilling the alveolar bone using a dedicated drill, placing a fixture into the procedure ball, fusion fusion to the alveolar bone, and then attaching the abutment to the fixture, and then covering the abutment with the final prosthesis. Is completed.

This implant procedure has been disclosed in Korean Patent Publication No. 10-2014-0079380 "How to use the implant and the implant for filling the perforation of bone tissue".

On the other hand, Figure 1 is a view schematically showing the structure of the upper jaw 11 and the lower jaw 13, the implant 40 is to be treated. As shown in the maxilla 11, the maxillary sinus 12 is formed on both sides. The maxillary sinus 12 is one of the sinus cavities formed in the human skull above the maxillary posterior region, and is a pair of cavities. Since the maxillary posterior alveolar bone 21 is in contact with the maxillary sinus 12, the thickness of the alveolar bone 210 is thin and the density is low.

If the thickness of the alveolar bone where the implant 40 is to be treated is low and the density is low, the fixture 41 of the implant 40 is not firmly supported and the alveolar bone 21 is broken, so there are many difficulties in the procedure of the implant 40.

Although the thickness of the alveolar bone is thin, when the implant 40 is applied to the maxillary posterior alveolar bone 21, the implant 40 may be detached and disappeared into the maxillary sinus 12. When the implant 40 is separated into the maxillary sinus 12, the implant 40 must be removed through surgery, resulting in great discomfort and pain to the patient.

Therefore, as shown in the upper part of FIG. 2, the maxillary sinus 12 and the membrane 12a that form it are struck down so that there is not enough space for planting the implant 40 between the maxillary sinus 12 and the alveolar bone 21. , Filling the bone in the space of the maxillary sinus (12) is to perform maxillary sinus surgery to enable implant placement.

As shown in the lower part of FIG. 2, the maxillary sinus surgery lifts the membrane 12a forming the maxillary sinus 12 using a mechanism penetrating the lower side of the gum and filling the bone graft material 30, and the implant 40. ) Is a method of implanting.

On the other hand, the lower jaw 13 of the face, as shown in Figure 1, the lower extremity neural tube 15 is present. Hachizo neural tube (15) is in close proximity to or attached to the wisdom teeth to extract the wisdom teeth or implant procedures should be careful. If the lower extremity neural tube 15 is damaged at the time of implant 40, paralysis of skin tissues may occur and paralysis may occur to the lips.

Therefore, when using the method of drilling the alveolar bone 21 and inserting the fixture 41 for the procedure of the conventional implant, the difficulty of performing the maxillary cohabitation and care must be taken not to touch the lower extremity neural tube 15 There is this.

In addition, conventional implants have the form of a root-type implant that is to penetrate the inside of the alveolar bone. Since these root implants are used to perforate the alveolar bone 21 and insert the fixture 41 for the procedure, the difficulty of performing maxillary cohabitation and care must be taken not to touch the lower alveolar neural tube 15. There is difficulty.

In addition, even when the bone quality is bad or the width or height of the bone is insufficient, the implant procedure is difficult, there was a restriction to use a denture rather than an implant.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

3 is an exemplary view showing a state in which the lid-type implant assembly 100 according to the present invention, Figure 4 is an exploded perspective view showing an exploded structure of the lid-type implant assembly 100 according to the present invention, 5 is a cross-sectional view showing a state in which the lid implant assembly 100 has been performed.

Cover type implant assembly 100 according to the present invention by drilling the alveolar bone 21 where the teeth are to be removed and the implant should be fixed to the alveolar bone cover 110 without fixing the fixture (41 in Fig. 2) Combining as if wrapped, the dental prosthesis 140 is coupled to the alveolar bone cover 110 to complete the procedure.

Accordingly, regardless of the maxillary part near the maxillary sinus, the mandibular part near the neural tube (15) neural tube, bad bone quality or lack of width or height of the bone, the lid-type implant assembly 100 of the present invention is safely operated. I can receive it.

In particular, when comparing the conventional FIG. 2 and FIG. 3 of the present invention, the implant can be performed using the lid-type implant assembly 100 without having to perform the maxillary sinus elevation, so that both the operator and the patient can safely operate without risk. There is an advantage.

Cover type implant assembly 100 according to the present invention is the alveolar bone cover 110 is coupled to cover the alveolar bone 21 of the portion to be implanted, and the cover coupling shaft 120 extending perpendicular to the alveolar bone cover 110 ), An abutment 130 inserted into the cover coupling shaft 120, and a dental prosthesis 140 coupled to an end of the abutment 130.

The alveolar bone cover 110 is a cover body 111 coupled to cover the portion facing the oral cavity of the alveolar bone like a saddle of the horse, a plurality of coupling holes 113 formed in the cover body 111, the coupling hole And a fixing member 115 inserted into the 113. The alveolar bone cover 110 is coupled to the lower region of the alveolar bone 21 in the case of the upper jaw, and coupled to the upper region of the alveolar bone 21 in the case of the lower jaw.

Cover body 111 is formed in a shape that can cover as necessary for the cross-sectional shape of the alveolar bone (21).

As shown in FIG. 4, when the cross-sectional shape of the alveolar bone 21 is circular, the alveolar bone cover 110 is formed in a semicircular shape. Since the cover body 111 is formed in a form surrounding the outer surface of the alveolar bone 21, the cover-type implant assembly 100 of the present invention weakens the strength of the alveolar bone when compared to a conventional implant of the alveolar bone 21. Rather, it serves to protect the alveolar bone. As a result, after the conventional implants, the gums may be lowered or the bones melted due to poor management. However, when the lid-type implant assembly 100 according to the present invention is used, there is an advantage that it can be used more stably.

Here, the alveolar bone 21 forming the upper jaw and the lower jaw are formed with different thicknesses as shown in FIG. 4 along the longitudinal direction. That is, the diameters of the respective regions are formed differently along the longitudinal direction. Accordingly, the surface of the alveolar bone 21 may have a protruding portion or a recessed area (d1 ≠ d2 ≠ d3).

The cover body 111 according to a preferred embodiment of the present invention can form the shape so that the cover-type implant 100 is stably maintained regardless of the thickness of the alveolar bone 21 and to create a more aesthetic dental prosthesis. . In this case, when the cover body 111 is coupled to the alveolar bone 21, the surface of the alveolar bone 21 is bumpy but the outer surface to which the cover body 111 is coupled may be smoothly formed.

In this case, in the separation space generated by the difference in diameter between the alveolar bone 21 and the cover body 111 may be filled with the bone graft material 30, as shown in Figure 5, the cover body 111 as much as that portion It is also possible to eliminate the separation space by increasing the thickness of. The bone graft material 30 filled in the separation space is filled in the separation space so that the alveolar bone cover 110 and the alveolar bone 21 are fused and fixed to each other.

Here, the cover body 111 is formed in the form of a net through which the plurality of coupling holes 113 are formed. The fixing member 115 may be inserted through the coupling hole 113. The alveolar bone cover 110 is covered with the alveolar bone 21, and then the bone graft material 30 is introduced through the coupling hole 113. At this time, the fixing member 115 is inserted to assist the position of the alveolar bone 21, the bone graft material 30 and the alveolar bone cover 110 to be fixed.

After the bone graft material 30 is fixed, the fixing member 115 is separated from the coupling hole 113 or maintained in a coupled state.

Here, the inner surface of the alveolar bone cover 110 may be a surface treatment to promote bone fusion. That is, the inner surface of the alveolar bone cover 110 is not smooth, and the surface is roughly processed to a certain range to allow bone cells of the bone graft material 30 to stick together more easily. And, the outer surface of the alveolar bone cover 110 can be treated so that the gum (23 of Figure 3) is well coupled.

Cover coupling shaft 120 is connected to the alveolar bone cover 110 and the abutment 130 is coupled to each other. Cover type implant assembly 100 according to a preferred embodiment of the present invention is formed integrally with the alveolar bone cover 110 as shown in FIG. That is, the cover coupling shaft 120 is manufactured by molding together with the alveolar bone cover 110 through a three-dimensional printer.

Cover coupling shaft 120 is formed to extend a predetermined length toward the oral cavity, the abutment 130 is coupled to the inner insertion hole 121 is formed. An internal thread 121a is formed on an inner wall surface of the inner insertion hole 121 to be screwed with the abutment 130.

Since the cover coupling shaft 120 is formed integrally with the alveolar bone cover 110, it is possible to omit the process of puncturing the fixture to the alveolar bone during the conventional implant procedure, accordingly the location of the alveolar bone and the density, height, It is possible to operate the lid implant assembly 100 irrespective of the thickness and the like.

Cover coupling shaft 120 is formed to correspond to the shape of the abutment 130 is coupled.

The abutment 130 is coupled to the cover coupling shaft 120, and then secures the dental prosthesis 140. Here, the abutment 130 and the dental prosthesis 140 may be a known form.

The abutment 130 may be screwed into the cover coupling shaft 120, as shown, or may be coupled in other ways in some cases. In addition, the abutment 130 may be integrally coupled to the cover coupling shaft 120.

On the other hand, Figure 6 is an exploded perspective view showing the exploded configuration of the lid-type implant assembly 100a according to another embodiment of the present invention.

Cover type implant assembly 100 according to the preferred embodiment described above was formed in the form having a relatively constant diameter alveolar bone cover 110, regardless of the shape of the alveolar bone (21). On the other hand, the cover-type implant assembly 100 according to another embodiment is formed such that the alveolar bone cover 110a has the same shape as the shape of the alveolar bone 21.

That is, it is formed so that there is a diameter change of the same shape as the diameter change of the alveolar bone 21. Accordingly, the gap between the alveolar bone 21 and the cover body 111a is uniformly formed, and the bone graft material 30 filled therein is also filled with a uniform amount.

In addition, the alveolar bone cover 110a according to another embodiment is provided to separate the cover coupling shaft (120a). The cover coupling shaft 120a is provided to be screwed to the shaft insertion hole 117 of the cover body 111a.

In this case, only the cover coupling shaft 120a is molded by the 3d printer, and the cover coupling shaft 120a is separately manufactured. The operator combines the alveolar bone cover 110a to the alveolar bone 21 and fills the bone graft material 30 through the coupling hole 113 to fix the alveolar bone cover 110a and the alveolar bone 21 by bone fusion. The shaft 120a is screwed into the shaft insertion hole 117 to fix the position.

In some cases, the cover coupling shaft 120a may be inserted into the shaft insertion hole 117 to fill the bone graft material 30 so as to be fused with the bone to fix the position.

The manufacturing process and the procedure of the cover-type implant assembly 100 according to the present invention having such a configuration will be described with reference to FIGS. 3 to 7.

In order to manufacture the lid-shaped implant assembly 100 of the present invention, as shown in Figure 7 to take a three-dimensional image of the alveolar bone 21 of the patient (S110). The three-dimensional shape of the alveolar bone 21 of the patient is photographed using three-dimensional imaging means such as CT.

In addition, the 3D shape of the alveolar bone cover 110 to be coupled to the alveolar bone 21 at the position where the lid-type implant assembly 100 is to be treated is designed using the 3D shape design tool (S111). Here, the designer may design the alveolar bone cover 110 to correspond to the curved shape of the alveolar bone 21, or may design the alveolar bone cover 110 in a form having a constant curvature regardless of the curved shape of the alveolar bone 21.

In addition, the cover coupling shaft 120 to the alveolar bone cover 110 to determine whether to be fixed integrally or independently detachable coupling. Then, the shape of the alveolar bone cover 110 is designed as determined.

Input the design of the designed alveolar bone cover 110, to form the alveolar bone cover 110 with a 3d printer (S113). At this time, the type and shape method of the 3d printer may be determined in consideration of the material and shape of the alveolar bone cover 110 (whether the cover coupling shaft is integrally formed).

When the alveolar bone cover 110 is manufactured in the 3d printer, the abutment 130 and the dental prosthesis 140 corresponding thereto are manufactured.

For the procedure of the cover implant assembly 100, the operator dissecting the gum of the patient, and places the alveolar bone cover 110 in the alveolar bone 21 (S115). Then, the bone grafting material 30 is put into the spaced space between the alveolar bone cover 110 and the alveolar bone 21 to fusion (S117). At this time, in some cases, the fixing member 115 is inserted to assist in fixing the position.

When the alveolar bone cover 110 and the alveolar bone 21 are fixed, the fixing member 115 is separated. When the cover coupling shaft 120 is integrally coupled to the alveolar bone cover 110 as shown in FIG. 4, the abutment 130 is directly fixed to the cover coupling shaft 120 (S119) and the abutment. The dental prosthesis 140 is coupled to the cement 130.

When the cover coupling shaft 120a is separated from the alveolar bone cover 110a as shown in FIG. 6, the cover coupling shaft 120a is coupled to the shaft insertion hole 117. Then, the abutment 130 is fixed to the coupling shaft 120a (S119), and the dental prosthesis 140 is coupled to the abutment 130.

When the treatment of the lid-type implant assembly 100 is completed on the alveolar bone 21, the implantation of the alveolar bone cover 110 may be completed in such a manner that the alveolar bone cover 110 covers the alveolar bone 21.

FIG. 6 illustrates a case where the lid-type implant assembly 100 is performed on the upper jaw, and when the lid-type implant assembly 100 is performed on the lower jaw, the alveolar bone cover 110 is coupled to the upper portion of the alveolar bone 21. do.

As a result, as shown in FIG. 3, the procedure of drilling the alveolar bone 21 to drill a hole and inserting the fixture 41 to perform the conventional implant 40 may be omitted.

Since the process of drilling the alveolar bone 21 is omitted, the alveolar bone cover 110 may be combined with the alveolar bone cover 110 regardless of the location of the alveolar bone 21, the bone size, the bone height, and the like. . Therefore, there is no need to perform maxillary sinus elevation, which is a large risk, and there is no risk of touching the lower extremity neural tube 15 neural tube.

In addition, since there is no process of drilling using a drill, the procedure does not have much bleeding, so the pain of the patient is small and management after the procedure may be easy. In the same context, the practitioner can perform the procedure more safely and without risk.

In addition, since the lid-type implant assembly of the present invention can be performed irrespective of the condition of the alveolar bone, it may provide an opportunity for more people to be treated.

In addition, the lid-type implant assembly according to the present invention is formed in the form tailored to the person, since the alveolar bone cover is molded in a three-dimensional print based on the three-dimensional shape of the alveolar bone of the patient obtained through the three-dimensional imaging. As a result, since the alveolar bone cover is molded to a size corresponding to the alveolar bone of the person, there is an advantage that the aesthetics can be improved as compared with the conventional implant.

8 and 9, when the cross-sectional shape of the alveolar bone 21 is circular, the alveolar bone cover 110 is formed in a semicircular shape. Since the cover body 111 is formed in a shape surrounding the outer side of the alveolar bone 21, the alveolar bone-reinforced implant assembly 100b of the present invention weakens the strength of the alveolar bone when compared to a conventional implant of the alveolar bone 21. Rather than making a role to protect the alveolar bone. Thereby, after performing the conventional implant, the gum may go down or the bone melts due to poor management, but there is an advantage that the alveolar bone reinforced implant assembly 100b according to the present invention can be used more stably. .

 Here, the alveolar bone 21 forming the upper and lower jaw is formed in a different thickness as shown in Figure 8 along the longitudinal direction. That is, the diameters of the respective regions are formed differently along the longitudinal direction. Accordingly, the surface of the alveolar bone 21 may have a protruding portion or a recessed area (d1 ≠ d2 ≠ d3).

Cover body 111 according to a preferred embodiment of the present invention can form the shape so that the alveolar bone reinforced implant (100b) can be stably maintained, regardless of the thickness of the alveolar bone 21 to create a more aesthetic dental prosthesis have. In this case, when the cover body 111 is coupled to the alveolar bone 21, the surface of the alveolar bone 21 is bumpy but the outer surface to which the cover body 111 is coupled may be smoothly formed.

In this case, the cover body 111 is formed to match the shape of the alveolar bone 21, it may be formed so that there is no space for the bone graft material 30 is injected between the alveolar bone (21). In addition, the cover body 111 is manufactured so that a predetermined clearance is formed between the alveolar bone 21, it is possible to add the bone graft material 30 to the space. The bone graft material 30 filled in the separation space is filled in the separation space so that the alveolar bone cover 110 and the alveolar bone 21 are fused and fixed to each other.

As shown in (a) of FIG. 13, the contact protrusion 112 is formed to protrude on the inner wall surface of the cover body 111 to contact and support the outer circumferential surface of the alveolar bone 21. Since the close contact 112 forms an inner wall surface and an uneven structure of the cover body 111, the contact area with the alveolar bone 21 is increased.

When the adhesion protrusion 112 comes into contact with the outer circumferential surface of the alveolar bone 21, an empty area is generated due to the uneven structure. When the bone graft material 30 is filled in this empty area and the time elapses, the alveolar bone 21 and the bone graft material 30 fill the space between the contact protrusions 112 as shown in FIG. As a result, the coupling force and the holding force between the cover body 111 and the alveolar bone 21 may be improved.

Here, the protruding height (l1) from which the close protrusion 112 protrudes toward the alveolar bone 21 may be differently formed along the inner wall surface of the cover body 111. That is, the plurality of contact protrusions 112 may have different protrusion heights and shapes to correspond to the shape of the outer diameter of the alveolar bone 21 that is in contact with each other.

Here, the shape of the contact protrusion 112 may be provided in a hemispherical shape, it may be provided in a variety of cross shape, polygonal shape, donut shape and the like.

In addition, as shown in FIG. 10, the contact protrusion 112a may be provided in a stepped form. Since the stepped contact protrusion 112a has a horizontal plane and a vertical plane formed repeatedly, the horizontal support force and the vertical support force can be realized together with the hemispherical contact protrusion 112 described above. Accordingly, there is an advantage that the stepped contact protrusion (112a) can implement a more stable support force than the hemispherical contact protrusion (112).

The horizontal width l2 and the height h1 of the stepped contact protrusion 112a may be variably formed to correspond to the external shape of the alveolar bone 21 in contact.

The contact protrusion 112 may not be formed in only one shape over the cover body 111, but may have a combination of structures having various cross-sectional shapes according to the shape of the alveolar bone 21. That is, hemispherical, stepped, cross, etc. may be formed by mixing.

Here, the plurality of coupling holes 113 may be formed through the cover body 111. Through the coupling hole 113, the fixing member 115 for fixing the cover body 111 to the alveolar bone 21 may be inserted. The alveolar bone cover 110 is covered with the alveolar bone 21, and then the bone graft material 30 is introduced through the hole other than the coupling hole 113 or the alveolar bone cover 110. At this time, the fixing member 115 may be inserted to assist the positions of the alveolar bone 21, the bone graft material 30, and the alveolar bone cover 110 to be fixed.

After the bone graft material 30 is fixed, the fixing member 115 is separated from the coupling hole 113 or maintained in a coupled state.

On the other hand, the coupling hole 113 is separated from the fixing member 115 may be utilized as a space for filling the bone graft material, it may be used as a space for the placement of the teeth adjustment site or other structures.

On the other hand, the cover body 111 may be provided with an insertion support shaft 114 as shown in (a) of FIG. The insertion support shaft 114 extends a predetermined length toward the alveolar bone 21 from the inner wall surface of the cover body 111 and is inserted into the recessed area 21a of the alveolar bone 21 so that the cover body 111 is the alveolar bone 21. It serves as a support shaft to be coupled to.

Insertion support shaft 114 is formed to a length that can be inserted into the recessed area (21a) from the inner wall surface of the cover body 111, as shown in (b) of FIG. The length of the insertion support shaft 114 may be formed to correspond to the outer surface shape of the alveolar bone 21, the number of the insertion support shaft 114 formed on the cover body 111 according to the shape of the alveolar bone 21 It can be formed differently.

On the other hand, the end of the insertion support shaft 114 is formed to be bent hook ring (114a) to be fixed in the alveolar bone (21). The catching ring 114a may be formed in various shapes such as "a" shape and "T" shape according to the shape of the alveolar bone 21.

On the other hand, Figure 12 (a) and (b) is an exemplary view showing a modified example of the alveolar bone cover (110c) of the alveolar bone reinforced implant assembly 100b of the present invention.

The alveolar bone cover 110c according to the modification has an inner cover 111a contacting the alveolar bone 21 and an outer cover 111b spaced a predetermined distance from the inner cover 111a as shown in FIG. Formed separately. The inner cover 111a and the outer cover 111b are coupled to each other with an edge area, and are disposed at predetermined intervals in the remaining areas.

The inner cover 111a may be formed in a polygonal network structure so that bone cells of the bone graft material can be more easily attached. That is, it may be formed in a honeycomb-shaped network structure.

At this time, the separation space 111c between the outer cover 111b and the inner cover 111a is formed to be empty to act as a space to fill the bone graft material.

Meanwhile, in some cases, as shown in FIG. 12B, the filler 111d may be filled between the outer cover 111b and the inner cover 111a. The filling material 111d is formed in a network shape having a honeycomb-like structure to form a structure to which bone graft material can adhere. As a result, the alveolar bone 21 and the alveolar bone cover 110 can be coupled more quickly.

In addition, in some cases, the outer cover 111b may also be formed in a mesh network to form a structure to which the bone graft material may be attached.

On the other hand, as shown in Figure 12 (a) may be provided with a hook connection portion 117 on the outside of the alveolar bone cover (110c). Hook connection portion 117 is extended to the outside of the gum and coupled to the hook or button formed on the gum or orthodontic (not shown) may help in orthodontics.

Hook connection portion 117 is formed to a length that can penetrate the gum from the outer surface of the alveolar bone cover (110c). The end of the hook connection portion 117 is provided with a coupling member (117a) coupled to the hook or button.

Here, the alveolar bone cover 110 is manufactured based on the results of the three-dimensional imaging of the alveolar bone 21 of the patient. That is, the alveolar bone cover 110 is designed to correspond to the outer curved shape of the alveolar bone 21 based on the 3D image of the alveolar bone 21.

In the design process, the cover body 111, the contact protrusion 112 is designed together. And, in some cases, the insertion support shaft 114, the coupling hole 113, the hook connecting portion 117 and the like are integrally designed.

Since the alveolar bone-reinforced implant assembly 100b is custom-made to fit the shape of the alveolar bone of the patient, it can be more easily performed on the alveolar bone of the patient, the pain of the patient can be reduced during the procedure, and the risk can be reduced.

Cover coupling shaft 120 is connected to the alveolar bone cover 110 and the abutment 130 is coupled to each other. Alveolar bone reinforced implant assembly 100b according to a preferred embodiment of the present invention is the cover coupling shaft 120 is integrally formed on the alveolar bone cover (110). That is, the cover coupling shaft 120 is manufactured by molding together with the alveolar bone cover 110 through a three-dimensional printer.

Cover coupling shaft 120 is formed to extend a predetermined length toward the oral cavity, the abutment 130 is coupled to the inner insertion hole 121 is formed. An internal thread 121a is formed on an inner wall surface of the inner insertion hole 121 to be screwed with the abutment 130.

Since the cover coupling shaft 120 is formed integrally with the alveolar bone cover 110, it is possible to omit the process of puncturing the fixture to the alveolar bone during the conventional implant procedure, accordingly the location and density of the alveolar bone, bone, The alveolar bone-reinforced implant assembly 100b can be treated regardless of the thickness.

Cover coupling shaft 120 is formed to correspond to the shape of the abutment 130 is coupled.

The abutment 130 is coupled to the cover coupling shaft 120, and then secures the dental prosthesis 140. Here, the abutment 130 and the dental prosthesis 140 may be a known form.

The abutment 130 may be screwed into the cover coupling shaft 120, as shown, or may be coupled in other ways in some cases. In addition, the abutment 130 may be integrally coupled to the cover coupling shaft 120.

Alveolar bone-reinforced implant assembly 100b according to a preferred embodiment of the present invention is formed in a form in which the abutment 130 is screwed to the cover coupling shaft 120, which is just one example and in Figure 12 (a) As shown, the cover coupling shaft 120a may be formed in a structure that is directly coupled with the dental prosthesis 140. That is, the thread is formed on the upper cover coupling shaft 120a may be directly coupled to the dental prosthesis 140.

In addition, the cover coupling shaft 120b may be detachably coupled to the alveolar bone cover 110 as shown in FIG. 13. The cover coupling shaft 120b may have a coupling surface 125 inserted into the coupling window 116 of the cover body 111. At this time, the coupling surface 125 may be fixed to the coupling window 116 by a fixing means.

Meanwhile, the alveolar bone reinforced implant assembly 100f of the present invention may be provided such that the alveolar bone cover 110 is divided into a plurality of cover bodies 111 ′ and 111 ″ as shown in FIG. 14.

Considering the various shapes of the alveolar bone 21, there may be a case in which the alveolar bone cover 110 is not covered by the alveolar bone 21 at a time by the shape of the undercut. In this case, as shown in FIG. 10, the alveolar bone cover 110 may be divided into a plurality of cover bodies 111 ′ and 111 ″ divided by diagonal lines X.

When the cover body 111 ', 111 "is divided in this way, it is preferable that the cover coupling shaft 120 is positioned on either side.

The manufacturing process and the procedure of the alveolar bone reinforced implant assembly 100b according to the present invention having such a configuration will be described with reference to FIGS. 9 to 14.

In order to manufacture the alveolar bone-reinforced implant assembly 100b of the present invention, a three-dimensional image of the alveolar bone 21 of the patient is taken. The three-dimensional shape of the alveolar bone 21 of the patient is photographed using three-dimensional imaging means such as CT.

Then, the three-dimensional shape of the alveolar bone cover 110 to be coupled to the alveolar bone 21 at the position where the alveolar bone reinforced implant assembly 100b is to be treated is designed using a three-dimensional shape design tool. Here, the designer may design the alveolar bone cover 110 to correspond to the curved shape of the alveolar bone 21, or may design the alveolar bone cover 110 in a form having a constant curvature regardless of the curved shape of the alveolar bone 21.

At this time, the shape of the plurality of contact protrusions 112 are designed and arranged on the inner wall surface of the cover body 111 so as to correspond to the curved shape of the alveolar bone 21.

In addition, the cover coupling shaft 120 to the alveolar bone cover 110 to determine whether to be fixed integrally or independently detachable coupling. Then, the shape of the alveolar bone cover 110 is designed as determined.

At this time, the type and shape method of the 3d printer may be determined in consideration of the material and shape of the alveolar bone cover 110 (whether the cover coupling shaft is integrally formed).

When the alveolar bone cover 110 is manufactured in the 3d printer, the abutment 130 and the dental prosthesis 140 corresponding thereto are manufactured.

For the treatment of the alveolar bone-reinforced implant assembly 100b, the operator cuts the gum of the patient and places the alveolar bone cover 110 on the alveolar bone 21. At this time, the plurality of contact protrusions 112 are disposed on the outer surface of the alveolar bone 21.

 And, as shown in FIG. 9 (b) is injected into the bone graft material 30 in the separation space between the alveolar bone cover 110 and the alveolar bone 21 to fusion. The bone graft material 30 is filled between the contact bone 112 of the alveolar bone 21 and the cover body 111. Accordingly, the bonding area of the bone graft material 30 and the cover body 111 and the alveolar bone 21 may be improved, and thus the holding force may be improved.

At this time, in some cases, the fixing member 115 is inserted to assist in fixing the position.

When the alveolar bone cover 110 and the alveolar bone 21 are fixed, the fixing member 115 is separated. When the cover coupling shaft 120 is integrally coupled to the alveolar bone cover 110 as shown in FIG. 8, the abutment 130 is directly fixed to the cover coupling shaft 120 and the abutment 130 is provided. Combine the prosthesis 140 to).

When the treatment of the alveolar bone-reinforced implant assembly 100b is completed in the alveolar bone 21 as described above, the treatment of the implant may be completed in the form in which the alveolar bone cover 110 covers the alveolar bone 21.

On the other hand, Figures 15 to 17 is an exemplary view showing the alveolar bone reinforced implant assembly 200 according to another embodiment of the present invention.

The alveolar bone reinforced implant assembly 100b of the present invention described above is formed in a surface shape in which the alveolar bone cover 110 covers the upper surface of the alveolar bone 21 like a saddle. On the other hand, the alveolar bone reinforcement implant assembly 200 according to another embodiment of the present invention is formed of the alveolar bone cover frame 210 formed by coupling a plurality of bar-shaped frame.

Figure 15 (a) is a perspective view of the alveolar bone cover frame 210. As shown, the alveolar bone cover frame 210 has a main horizontal frame 211 disposed in the horizontal direction on the upper side of the alveolar bone 21, and the two sides of the alveolar bone 21 in the vertical direction.

At this time, the abutment 230 is coupled to the upper surface of the main horizontal frame 211, and the abutment 230 is coupled to the dental prosthesis 240 (see FIG. 12B).

The alveolar bone cover frame 210 is formed by combining the main horizontal frame 211 and the main vertical frame 213 having a predetermined thickness orthogonally, so as not to partially cover the entire outer surface of the alveolar bone 21. As a result, a plurality of margin spaces 216 are formed between the main horizontal frame 211 and the main vertical frame 213.

The bone graft material 30 may be added into the alveolar bone 21 through the margin space 216. The bone graft material 30 is filled between the alveolar bone cover frame 210 and the alveolar bone 21 through the margin space so that the alveolar bone cover frame 210 and the alveolar bone 21 are fused and fixed to each other. At this time, since the size of the margin space 216 is large, there is an advantage that can vary the size of the bone graft material (30) to be implanted.

In addition, the margin space 216 may be used to perform a ready-made implant that is being sold.

The thickness of the main horizontal frame 211 and the main vertical frame 213 may be formed in various ways, the length may be designed in consideration of the gum height and alveolar bone height of the patient. Although not shown in the drawings, the close protrusions 112 may protrude from the inner wall surfaces of the main horizontal frame 211 and the main vertical frame 213.

Fixing member coupling holes 217 are provided at ends of the main horizontal frame 211 and the main vertical frame 213. Fixing member (115 of FIG. 8) is inserted into the fixing member coupling hole 217 may assist to fix the position of the alveolar bone cover frame 210 and the alveolar bone 21 and bone graft material (30). The fixing member 115 may be separated from the fixing member coupling hole 217 after the bone graft material 30 is fixed.

The fixing member coupling hole 217 may be formed at various positions to fix the alveolar bone cover frame 210 in consideration of the surface shape, height, bone loss, etc. of the alveolar bone 21. The fixing member coupling hole 217 may be formed at the ends of the main horizontal frame 211 and the main vertical frame 213, or may be formed in the center region.

In addition, the main horizontal frame 211 and the main vertical frame 213 may be formed through the plate surface, in some cases, as shown in Figure 16 (a) of the fixing member coupling end 218 may be formed separately. have. The number to which the fixing member 115 is coupled may also be modified in various numbers depending on the position.

Here, various means known in addition to the fixing member 115 described above may be used as a means for coupling the alveolar bone cover frame 210 to the alveolar bone 21.

Meanwhile, one or more auxiliary frames 215 may be coupled between the main horizontal frame 211 and the main vertical frame 213. The auxiliary frame 215 is located where bone loss is concerned to prevent external loss of the alveolar bone 21. The auxiliary frame 215 may be positioned horizontally or vertically in some cases and diagonally in the main horizontal frame 211 and the main vertical frame 213. The auxiliary frame 215 may be formed to the same thickness as the main horizontal frame 211 and the main vertical frame 213, or may be formed relatively thin.

The main horizontal frame 211, the main vertical frame 213, and the auxiliary frame 215 may be coupled to each other in a symmetrical or asymmetrical fashion. In particular, the auxiliary frame 215 may be formed in the form of a net by plurally arranged in a portion where the alveolar bone is concerned, or the gum loss due to the periodontitis.

15B is a modified example of the alveolar bone cover frame 210a. As shown in the alveolar bone cover frame 210a, a plurality of main vertical frames 213a may be coupled to the main horizontal frame 211 as ribs. The plurality of main vertical frames 213a disposed on both sides of the main main horizontal frame 211 may be arranged symmetrically or alternately as illustrated. In addition, the main vertical frame 213a may be disposed in an irregular shape.

At this time, the auxiliary frame 215 may be regularly or irregularly coupled to the main horizontal frame 211 and the main vertical frame 213a according to the shape of the alveolar bone 21, the surface curvature or depression.

Meanwhile, FIGS. 16A and 16B are exemplary views illustrating yet another modified example of the alveolar bone cover frames 210b and 210c.

The above-described alveolar bone cover frames 210 and 210a have a form in which the main vertical frame 213 and the auxiliary frame 215 are coupled to the main horizontal frame 211 disposed in the horizontal direction on the upper surface of the alveolar bone 21.

On the other hand, the alveolar bone cover frame 210b shown in (a) of FIG. 16 includes a figure frame 212 positioned on an upper surface of the alveolar bone 21 and a variable vertical frame 213a extending on both sides of the figure frame 212. It includes.

The figure frame 212 may be formed in various shapes such as a circle, a triangle, a rectangle, a pentagon, and a rhombus. The figure frame 212 penetrates inside to form a margin space 216. The variable vertical frame 213a extends at both ends of the figure frame 212 to support both sides of the alveolar bone 21.

Here, the main vertical frame 213 described above is formed in a semi-circular cross section, but the variable vertical frame 213a is formed in a "s" shape. In addition to the variable vertical frame 213a, the main frame 213 may be coupled to the figure frame 212.

The fixed member coupling hole 217 and the fixed member coupling end 218 may be selectively coupled to the variable vertical frame 213a and the figure frame 212. In addition, an auxiliary frame 215 may be coupled to the inside of the figure frame 212, between the figure frame 212 and the variable vertical frame 213a.

The alveolar bone cover frame 210c illustrated in FIG. 16B is provided with a figure plate 212a instead of a figure frame 212. A graph plate 212a, such as a circle, a rectangle, and a pentagon, is formed to cover the upper surface of the alveolar bone 21, and the main vertical frame 213 extends to both sides of the graph plate 212a to support the side surface of the alveolar bone 21. .

Here, as shown in FIGS. 16A and 16B, the alveolar bone cover frames 210b and 210c are formed in an articulated manner. That is, when the implant is to be performed on all of the plurality of neighboring teeth, it may be provided to be used by segmenting according to the number of teeth.

Here, one figure frame 212 is continuously formed in the alveolar bone cover frames 210b and 210c, or the figure plate 212a is formed continuously. However, this is only an example and may be formed by mixing the figure frame 212 and the figure plate 212a in some cases.

Here, as shown in (b) of FIG. 16, the alveolar bone cover frame 210c is formed in an articulated or integral manner, and when a plurality of teeth are extracted together, a plurality of dental prostheses on the upper surface of the alveolar bone cover frame 210c. 240 is coupled. In this case, the plurality of dental prostheses 240 may be formed independently of each other, or may be connected to each other by the bridge 241 as shown in the figure.

On the other hand, Figure 17 is an exemplary view showing a coupling state of the cover coupling shaft 220 and the alveolar bone cover frame 210 of the present invention. Cover coupling shaft 220 may be formed integrally with the alveolar bone cover frame 210, or may be manufactured and coupled separately with the alveolar bone cover frame 210.

Cover coupling shaft 220 may be integrally coupled to extend a predetermined length to the top of the alveolar bone cover frame (210). In addition, it may be coupled to the alveolar bone cover frame 210 through the coupling plate 225 as shown in FIG. The coupling plate 225 may be coupled to the upper portion of the margin space 216 or may be coupled to the main horizontal frame 211 or the main vertical frame 213 forming the alveolar bone cover frame 210. At this time, although not shown in the drawings, the coupling plate 225 may be fixed to the alveolar bone cover frame 210 by a fastening member such as a screw.

Here, the cover coupling shaft 220 may extend through the coupling plate 225 to a predetermined length downwardly and be inserted into the alveolar bone 21.

Meanwhile, FIGS. 18A and 18B illustrate modifications of the cover coupling shafts 220a and 220b. As shown in FIG. 18A, a screw thread 221 is formed outside the cover coupling shaft 220a and may be screwed with the abutment 230. To this end, the abutment 230 may be provided with a thread 231a corresponding to the thread 221 of the cover coupling shaft 220a.

And, the cover coupling shaft 220b is formed in the form of a smooth shaft as the outer surface of the shaft, as shown in Figure 18 (b) can be fitted into the shaft insertion hole (231b) of the abutment 230b. In this case, the abutment 230b may be omitted in some cases, and the dental prosthesis 240 may be directly coupled to the cover coupling shaft 220b.

19 and 20 are exemplary diagrams illustrating various modified examples of the abutment. The abutments 130 described above are coupled to the alveolar bone cover 110 through the cover coupling shaft 120 as shown in FIG.

However, as shown in FIG. 19A, the abutment 230c may be formed integrally with the alveolar bone cover frame 210 without a cover coupling shaft. The prosthesis 240 may be coupled to the abutment 230c formed as shown in FIG. 19B.

Here, when the alveolar bone cover frame 210 is inserted into the gum on the surface of the alveolar bone cover frame 210, the gum support protrusion 250 for contacting and supporting the gum may be formed to protrude.

The gum support protrusion 250 may be formed in the shape of a pointed protrusion as shown, or may be stepped in the form of a step. In addition, the gum support protrusion 250 may be formed in various forms that can support the gum.

In addition, the lower portion of the alveolar bone cover frame 210 may be integrally coupled to the reinforcing frame 260 extending toward the alveolar bone 21 vertically or inclined. The reinforcement frame 260 may be inserted into the alveolar bone 21 to serve as a support shaft such that the alveolar bone cover frame 210 is coupled to the alveolar bone 21. The reinforcement frame 260 is inserted into the alveolar bone 21 so that the state of the alveolar bone 21 is stably maintained by reinforcing the strength of the alveolar bone cover frame 210.

The reinforcement frame 260 may be formed in various lengths, angles, thicknesses, and the like according to the shape of the alveolar bone 21.

The abutment 230d may be detachably coupled to the alveolar bone cover frame 210 by the frame coupling member 235 as shown in FIG. 20A. A fastening member insertion hole 233 is formed in the axial direction through the abutment 230d, and the abutment coupling hole 216b is formed in the alveolar bone cover frame 210.

The lower portion of the abutment 230d is inserted into the abutment coupling hole 216b, and the frame coupling member 235 is inserted through the fastening member insertion hole 233. The frame coupling member 235 is screwed and fixed to the lower portion of the abutment coupling hole 216b through the abutment 230d.

At this time, the abutment 230d and the frame coupling member 235 may be formed to be accommodated in the alveolar bone cover frame 210 as shown in FIG. 20A, and FIG. 20B. As shown in the through the alveolar bone cover frame 210 may protrude a predetermined length (h) toward the alveolar bone 21 side.

Meanwhile, in some cases, as shown in FIG. 21, the dental prosthesis 240a may be integrally coupled to the alveolar bone cover frame 210. In this case, the dental prosthesis 240a may be directly coupled to the alveolar bone cover frame 210 without the cover coupling shaft 220 and the abutment 230.

On the other hand, the alveolar bone reinforcement implant assembly 200 according to another embodiment of the present invention has a large area of the margin space 216 on the surface by the shape of the alveolar bone cover frame 210. At this time, since the growth rate of the alveolar bone 21 and the growth rate of the gum are different, the gum may flow into the alveolar bone 21 through the margin space 216 of the alveolar bone cover frame 210.

As shown in FIG. 22, a blocking cover 270 may be provided to be coupled to the outer wall of the alveolar bone cover frame 210 to cover the margin space 216 to block the gum from entering the alveolar bone 21. . The blocking cover 270 may be formed of an absorbent material and absorbed over time so that it does not need to be separately removed. Alternatively, the blocking cover 270 may be formed of a non-absorbent material and may be removed by cutting the gum after a predetermined time.

When the blocking cover 270 is a non-absorbent material, the cover coupling member 271 couples the blocking cover 270 to the alveolar bone cover frame 210.

Figure 23 is an exemplary view showing a process in which the alveolar bone strengthening implant 200 of the present invention is performed in the place where the tooth is extracted. If the second tooth (C) located between the first tooth (A) and the third tooth (D) is extracted as shown in (a) of FIG. 23, the tooth is extracted as shown in (b) of FIG. 21.
