Description

Scan Body and Implant Assembly for Implants and Implant Method Using the Same

The present invention relates to a dental implant, and more particularly, to a scan body that can perform a digital scan more conveniently, an implant assembly comprising the same, and an implant treatment method using the same.

First, the structure of the dental implant in the oral cavity will be described with reference to FIG. 1. As shown, the dental implant, a fixture (2) fixed to the alveolar bone, a crown (4) having a shape corresponding to the tooth, and the fixture (2) and the crown (4) by connecting to each other It is common to consist of the abutment 6 which supports.

The fixture 2 corresponds to the root of a normal tooth and is formed of metal, and is fixed to the alveolar bone by using a screw formed on an outer surface thereof. The crown 4 corresponds to the crown of the tooth, and may be said to perform a substantial function as a tooth while the upper part is supported while being exposed on the gingiva. The crown 4 is supported in a fixed state while being connected to the fixture 2 via the abutment 6.

Here, a hexagonal groove is formed at an inner lower side of the fixture 2, and a hexagonal protrusion inserted into the hexagonal groove is formed at a lower end of the abutment 6. Here, forming the hexagonal grooves and hexagonal protrusions engaged with each other at the inner lower end of the picture and the lower end of the abutment 6 is such that the abutment 6 coupled to the fixture 2 is rotated by an external force. It is intended to be supported without. And instead of the hexagon as described above can be formed into a polygon that can prevent the rotation when they are combined with each other, for example, octagon, and the like.

As described above, in the state where the hexagonal projection formed at the lower end of the abutment 5 is inserted into the hexagonal groove formed in the fixture 2, the abutment 6 is fixed to the fixture 2 by a fixing screw (not shown). do. The crown 4 is then fixed to the abutment 6 using an adhesive. Next, a brief description will be made of a procedure for performing an implant having the above structure.

First, the fixture 2 is placed in the alveolar bone, that is, fixed, and then wait for a predetermined time (for example, 3 to 4 months) until the fixture is completed. When the bone bonding of the fixture 2 is completed, a healing abutment (not shown) is fastened to the fixture 2 for healing of the gingiva. Here, the healing abutment may be said to perform a function of forming an appropriate emergency profile so that the gingival can be healed to a certain shape for the crown to be coupled in a later process.

Such a healing abutment may be of a type that is fixed to the fixture 2 by using a separate screw, and integrally fixed directly to the fixture 2 by integrally providing a screw portion that is screwed into the inside of the fixture at a lower end thereof. There is also a type.

After the gingival is healed using the above-described healing abutment and a constant emergency profile is formed, a prosthetic manufacturing process for removing the healing abutment and forming the crown 4 fixed to the fixture 2 is performed. . This prosthetic manufacturing process can be roughly divided into two methods, by manually floating the mold using impression coping to form a crown, and using a scan adapter to obtain a three-dimensional image by using an oral scanner. It is divided into how to make a crown by using.

In the case of directly forming the mold by using the impression coping, the impression coping is fastened to the upper portion of the fixture 2, and a jelly impression agent is applied thereon. By the solidification of the impression agent, the spherical internal shape and the impression coping shape are reproduced in the impression material, and the prosthesis is manufactured using the impression material. However, this method can be said that the coping of the impression is inconvenient for the patient due to the handling and the use of the impression agent.

Therefore, in order to alleviate such inconvenience, it can be said that the recent development of a method for obtaining a three-dimensional shape using a digital oral cavity scanner and manufacturing a prosthesis based on the same. This trend can be said to be gradually increasing in response to the convenience of the patients and the needs of the times. In order to acquire a three-dimensional image of the inside of the oral cavity using a digital oral cavity scanner, scan is performed after fixing the scan adapter to the fixture 2 in place of the impression coping used in the conventional method described above.

As such, when performing a scan for acquiring a 3D image of the inside of the oral cavity, using a separate scan adapter accurately measures the exact position and orientation of the hexagonal grooves formed in the fixture 2 as described above. This is to accurately design the abutment and the crown fixed to the fixture 2. That is, according to the prior art, it can be said that a separate member called a scan adapter is used to recognize the thickness of the gum, the resulting depth of implantation, and the correct direction according to the patient.

However, according to the conventional implant method, the following disadvantages can be pointed out.

First, when scanning the structure of the oral cavity for accurate design of the prosthesis, it is pointed out that a disadvantage that the scan must be fixed after temporarily fixing a separate device called a scan adapter to the fixture. Such a disadvantage will be a burden on the patient receiving the implant procedure, and will appear to the doctor as an inconvenience that the procedure of the procedure is complicated.

In addition, according to the conventional procedure and the structure of the implant assembly, it can be seen that after placing the fixture in the alveolar bone, a separate member called a healing abutment is used while the gingiva is healed. This healing abutment is intended to enable the formation of an emergency file in the gingival, although it is used temporarily until the final abutment is fixed to the fixture and must be used.

Most of the conventional healing abutments have a circular cross section, but since the shape of the tooth has a variety of shapes depending on its position, it can be said that it is slightly different from the shape corresponding to each tooth. Therefore, during the procedure, the artificial tooth should be pushed into the small healed gingiva, which may cause some pain or severe deformity of the gingival. This is far from the recent trend toward patient-specific treatment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a main object of the present invention is to provide a member that can be used together in a scanning process for obtaining an intraoral image and a healing process for forming a desired emergency profile in the gingiva.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

2 is a cross-sectional view of the combined state of the implant assembly including a scan body according to the present invention, and Figure 3 is a cross-sectional view of the disassembled state, respectively. As shown, the implant assembly of the present invention, the fixture 10 is coupled to and supported by the alveolar bone, the scan body 20 is coupled to the fixture 10, and the fixture 10 and the scan body 20 It includes a fixing screw 30 for fixing to each other.

The fixture 10 may be referred to as a structure that is coupled to the alveolar bone to support the implant as a whole. As shown in FIG. 3, the fixture 10 has a coupling hole 14 extending from the top to the bottom by a predetermined length. In the middle of the coupling hole 14, a hexagonal groove 12 is formed.

Here, the hexagonal groove 12 is for preventing any rotation of the scan body 20 coupled to the fixture 10, and may be formed in another polygon such as an octagon. And the lower portion of the hexagonal groove 12 is formed with a threaded portion 18 is a female thread is processed on the inner surface, such a threaded portion 18 has a smaller diameter than the hexagonal groove 12, the fixing screw 30 is fastened It is part to be.

 In addition, the fixing screw 30 is for fixing the scan body 20 to the fixture 10. At the lower end, a screw part 32 having a male thread formed on an outer surface thereof is formed to be fixed to the screw part 18 of the fixture. The head 34 is molded to have a relatively large diameter. The fixing screw 30 is said to allow the scan body 20 to be firmly supported by the fixture 10 by fastening them to each other while the scan body 20 is inserted into the fixture 10. Can be.

The scan body 20 of the present invention has a function as a reference body to obtain an accurate image when acquiring a three-dimensional image in the oral cavity, and has two functions for forming an emergency profile required by the gingiva. . As shown in FIG. 3, the scan body 20 has a through hole 21 penetrating up and down at a central portion, and the fixing screw 30 has a fixture 10 through the through hole 21. It is fixed to). And the upper part of the through-hole 21 is formed with a locking projection 28 is caught the head 34 of the fixing screw 30.

Next, the scan body 20 of the present invention will be described in more detail with reference to FIGS. 4 to 6. First, the scan body 20 of the present invention includes a hexagonal protrusion 22 formed at a lower end portion of the scan body 20 so as to be inserted into the hexagonal groove 12 of the fixture 10 described above. Since the hexagonal projections 22 have a shape corresponding to the hexagonal grooves 12 of the fixture 10, each surface has the same direction.

In addition, the body portion 24 formed on the upper portion of the scan body 20 is provided with at least one flat portion 25. In the embodiment shown in Figure 4, the planar portion 25 is formed to have the same angle, for example, it can be seen that consists of three having the same angle as each side of the equilateral triangle. In the embodiment shown in Figure 5 the planar portion 25 is composed of a pair formed in parallel to each other, in the embodiment shown in Figure 6 the planar portion 25 is made of three adjacent to each other at right angles You can see that it is losing.

Thus, the connection part 26 which has at least one flat part 25 and connects them between the body part 24 formed in the upper part and the hexagonal protrusion part 22 formed in the lower part is formed. Since the body portion 24 is formed relatively larger than the hexagonal protrusions 22, the connection part 26 connects the body portion 24 and the hexagonal protrusions 22 while having a predetermined inclination.

The planar portion 25 of the scan body 20 may be referred to as a portion forming a plane, and the planar portion 25 is substantially parallel to one surface of the hexagonal groove 12 of the fixture 10. Is formed. This can be said that the planar portion 25 is the same as that formed in parallel with one side of the hexagonal projection 22 of the lower end. Forming the flat portion 25 of the scan body 20 in the same direction as one surface of the hexagonal projection 22 or the hexagonal groove 12 may provide accurate image information when the oral cavity scanner scans the image in the oral cavity. It can be said to be obtained.

That is, as described above, scanning the inside of the oral cavity using the oral scanner is to ensure that the exact position is known when the crown is designed substantially. Therefore, when scanning the inside of the oral cavity while the scan body 20 is mounted on the fixture 10, since the flat portion 25 has the same direction as the hexagonal groove 12 of the fixture 10, By the image obtained by the scan it is possible to obtain accurate information about the direction and the implantation depth of the hexagonal groove 12 of the fixture (10).

As described above, the image obtained by the oral cavity scanner in the state where the scan body 20 having the flat portion 25 is mounted includes information about the direction and the implantation depth of the hexagonal groove 12 of the fixture 10. Based on this, it is possible to accurately design the crown. That is, it can be seen that the scan body 20 according to the present invention can scan to obtain an image inside a sphere in a state in which it is attached to the fixture 10.

As described above, in the prior art, in order to obtain an image of the interior of the oral cavity, it is inconvenient to remove the healing abutment coupled to the fixture 10 and to attach a separate scan adapter to the fixture and then scan the interior of the oral cavity. There was this. However, according to the present invention, since it is possible to scan directly by using the scan body 20 fixed to the fixture, without mounting a separate scan adapter, it can be seen that the scanning process can be very convenient compared to the prior art. Can be. In addition, conventionally considering that the healing abutment must be coupled to the fixture after the scan using the scan adapter, the present invention does not need to remove or remount the scan body 20 as described above. Therefore, it will be appreciated that a procedure that is remarkably convenient for patients and doctors can be provided.

Next, the function as a healing abutment of the scan body 20 of the present invention will be described. As described above, the healing abutment is fixed to the fixture 10 so that after the fixture 10 is implanted in the alveolar bone, the emergent profile of the desired shape may be formed in the gingiva during the gingival process. Maintain a period of time. Since the conventional healing abutment had a certain shape irrespective of the shape and position of the teeth, it was uncomfortable for the patient and the doctor in the process of removing the healing abutment and mounting the prosthesis.

As described above, the scan body 20 of the present invention has a second function as a healing abutment in addition to the first function as a scan body which is fixed to the fixture 10 and used when scanning. That is, after the fixture 10 is placed, the fixture 10 is fixed to the fixture 10 and maintained for a certain period of time so that an optimal emergency profile is formed in the gingiva during the healing process of the gingiva.

The scan body 20 of the present invention is provided with at least one flat portion 25 as described above, which is an immersion having a cross section closest to a natural tooth because the cross-sectional shape is different according to the shape of the tooth. It is to be able to form a sea profile. For example, in the embodiment shown in Fig. 4, three planar portions 25 having an angle of about 60 degrees are formed so that the scan body 20 forms an equilateral triangle, which is most similar to the cross section of the maxillary mid incisors (front teeth). It can be said to be formed.

In addition, the scan body 20 according to the embodiment shown in FIG. 5 includes a pair of parallel planar portions 25, which can be said to be the most similar to the cross-sectional shape of the premolar (fang). The scan body 20 of the embodiment shown in FIG. 6 has a planar portion 25 adjacent to each other with an angle of approximately 90 degrees, which can be said that the molar tooth is most similar to the cross-sectional shape. In the present invention, it is understood that the scan body 20 having the cross-sectional shape closest to the natural tooth is proposed by forming at least one flat portion 25 as described above.

FIG. 7 exemplarily shows the shape of the tooth T so that the cross-sectional shape according to the position of the tooth can be easily understood, and the shape of the scan body 20 most suitable for each tooth also corresponds to each tooth. In addition, the mounting position of the fixture 10 is also illustrated as an example so that the scan body 20 can be applied to each tooth. Therefore, by appropriately selecting and fixing the scan body 20 of the present invention having a cross section closest to the natural tooth to the fixture 10, it will be possible to form an emergency profile close to the natural tooth.

As described above, it can be seen that the scan body 20 according to the present invention has two functions of knowing accurate image information when scanning and forming a desirable emergency profile when healing of the gingiva. And these two functions are to be performed around the flat portion 25 formed in the upper body portion of the scan body 20 and parallel to one surface of the hexagonal groove 12 of the fixture 10 Can be. In addition, since the flat part 25 of the present invention is apparently apparent, an advantage of being able to grasp the position of the hexagonal groove 12 of the fixture 10 can be expected.

Next, referring to FIG. 8, the fixing screw 30 for fixing the above-described scan body 20 to the fixture 10 will be described. The fixing screw 30 is for fixing the scan body 20 to the fixture 10 as described above. In addition, since the thickness of the gum is different for each person as described above, the length of the fixing screw 30 varies depending on the person when fixing the scan body 20 to the fixture 10. Therefore, the fixed screws currently produced are divided into several types, for example, 4mm, 6mm, 8mm, etc., and are used to fix the scan body 20 to the fixture 10 by selecting an appropriate one according to the condition of the patient. .

After the fixing screw 30 fixes the scan body 20 to the fixture 10, it is impossible to distinguish what kind of the fixing screw 30 is from the outside. In addition, if the length of the fixing screw 30 used is not known accurately, a problem may occur in the design of a crown or the like using an image obtained in the scanning process. That is, it can be said that accurate design of the prosthesis is possible by knowing exactly the length of the fixing screw 30 used for fixing the scan body 20 of the present invention.

According to the present invention, a marker 38 whose length is known is formed on the upper surface of the fixing screw 30. In the embodiment shown in Fig. 8, the marker 38 is formed of grooves of various shapes. For example, in the embodiment shown in Fig. 8A, the marker 38 is formed into a straight groove and is shown in Fig. 8B. In one embodiment, the marker 38 is molded without grooves, and in the embodiment shown in FIG. 8C, the marker 38 is molded into cross grooves.

And the marker 38 in the present invention can be said to display the length information of the fixing screw 30, for example, the groove of the straight has a length of 4mm, and the groove is not 6mm long Branches and cross-shaped grooves indicate that they are fixed screws having a length of 8 mm.

9 shows another embodiment of the present invention. In the description of this embodiment, a description of a portion overlapping with the above-described embodiment will be omitted. As shown, the scan body according to the present embodiment is provided with a torx-like protrusion 22a instead of the polygonal protrusion 22 of the above-described embodiment. Such a small protrusion 22a may be said to perform the same function as the hexagonal protrusion 22 described above. Therefore, it can be obvious that a torso-shaped groove having a shape corresponding to the torso-small protrusion 22a should be formed inside the fixture applied to the present embodiment.

The torso small protrusion 22a may also have the same shape as the hexagonal protrusion when the six vertices are substantially connected to each other. Therefore, even in this embodiment, the above-described flat portion 25 should be designed to be parallel to the line connecting the adjacent vertices. The term "polygon" in the present specification includes not only hexagons and octagons, but it should be defined as a concept including a shape that can be expressed as a polygon when a plurality of vertices are connected to each other as in the present embodiment. Therefore, for example, as shown in the present embodiment should be included, such as projections of the small or hexagonal star shape.

Next, a description will be given of an implant procedure using the scan body 20 of the present invention. Here, the technique of acquiring a three-dimensional image of the inside of the oral cavity using the oral cavity scanner and designing a crown or the like based on such an image is already known. Therefore, in the following description, the description of the already known parts will be simplified, and the characteristic parts of the present invention will be concentrated.

First performed in the implant procedure may be to fix the fixture 10 to the alveolar bone. After the fixture 10 is fixed to the alveolar bone, a certain period of time is required to completely adhere to the alveolar bone. In addition, it can be said that a certain time is required to heal damaged gingiva during the placement of the fixture 10.

To this end, after the fixture 10 is fixed to the alveolar bone, the scan body 20 of the present invention is coupled to the fixture 10. Coupling of the scan body 20 proceeds in a state where any rotation is prevented by inserting the hexagonal projections 22 at the lower end into the hexagonal grooves 12 inside the fixture 10. In this state, the scan body 20 is fixed to the fixture 10 using the fixing screw 30.

At this time, the fixing screw 30 penetrates the through hole 21 of the scan body 20, and the screw portion 32 at the lower end thereof is coupled with the screw portion 18 of the fixture 10, and the head of the fixing screw 30 is fixed. 34 is in a state of being caught by the locking jaw 28 of the scan body 20. In addition, the inclined connection part 26 of the scan body 20 is in close contact with the inclined ground surface 16 formed at the inlet of the coupling hole 14 of the fixture 10. Here, it can be seen that the lower limit position of the scan body 20 is determined by the inclined ground surface 16 of the fixture 10 and the inclined connection portion 26 of the scan body 20.

The combined state is illustrated in FIG. 2, and when a certain time elapses in this state, healing of the gingiva and fixation of the fixture 10 are completed. Next, a process of scanning a portion of the interior of the oral cavity to be implanted is performed. Such scanning is performed by a scanning apparatus, and since a program for designing a prosthesis based on such scanning apparatus and image information obtained by scanning is already commercially available, a detailed description thereof will be omitted.

In this scanning process, according to the present invention, scanning is performed in a state where the scan body 20 of the present invention is fixed to the fixture 10 without using a separate scan adapter. Since the scan body 20 of the present invention includes the flat portion 25 parallel to one side in the hexagonal groove 12 of the fixture 10 as described above, the scan body 20 is substantially accurate. The direction and position can be obtained, as well as the information about the length of the threaded portion of the fixing screw 30 can be accurately obtained through the marker 38 of the fixing screw 30. Based on the three-dimensional images and information thus obtained, it will be possible to select the correct design of the crown and the optimal abutment thereon.

In addition, according to the present invention, the scan body 10 is provided with at least one flat portion 25 as described above. In addition, the scan body 10 according to the present invention may be selected and used corresponding to the tooth to be treated in the embodiment shown in FIGS. Therefore, when the scan body 20 is fixed to the fixture 10 and a predetermined time has elapsed, the corresponding gingival closest to the natural teeth and most suitable for the crown and abutment obtained based on the above-described information. The profile will be formed.

Therefore, when the crown and abutment designed based on the image information obtained during the scanning process is completed, the fixing screw 30 is removed to remove the scan body 20, and the completed crown and abutment is attached to the fixture 10. Immobilization may terminate the procedure. And the abutment is fixed to the fixture 10 by a fixing screw, the crown is fixed to the abutment using an adhesive as described above.

Within the scope of the basic technical spirit of the present invention as described above, it will be obvious that various modifications are possible for a person skilled in the art. And it can be said that the protection scope of the present invention should be interpreted based on the appended claims.

Such scan body, implant assembly, and implant treatment method according to the present invention will be applicable to the dental implant industry, it is natural that the dentist will be able to more accurate diagnosis and optimal design by applying this, Patients will be able to minimize the pain associated with treatment, while at the same time being provided with a customized abutment that is most appropriate for them.
