Description

Induction bushing assembly for precision procedure of dental implant

The present invention relates to an induction bushing assembly embedded in a guide template for precision treatment of a dental implant, and can be performed in two steps by providing an inner bushing with a handle that can be fitted to an inner circumferential surface of the induction bushing. The present invention also relates to an induction bushing assembly capable of preventing an error during surgery by forming a figure symbol representing surgical information on a part of the induction bushing or the inner bushing.

The general surgical method of dental implants is to measure tissue information at the diagnosis stage, to plan the implant procedure from the measured information, and to designate the surgical instruments and to perform the surgery. The oral tissues of each person should be measured and progressed.

Implant length, diameter, and implantation angle should be different for each implant according to the patient's oral tissue information, for example, the thickness of the gingiva and alveolar bone, and the location of the nerve line. Of course, information on the exact length and diameter of the surgical instruments should be provided.

For this reason, conventional implant surgery, which requires the measurement of oral tissue in diagnosis and the establishment of a surgical plan based on it, and the measurement and correction in actual surgery, requires a very long operation time and high concentration, and thus must be treated accordingly. It is true that there is a lot of information to do.

In order to solve this problem, a precision guided implant surgery was devised so that the surgical plan established at the diagnosis stage can be realized in the oral cavity through a guide guide fitting called a guide template.

1 is a view showing a guide template 10 for implant surgery developed and filed by the applicant. The description of the illustrated guide template 10 has been filed in Korean Patent Application No. 10-2016-0036619 (filed March 28, 2016).

The illustrated guide template 10 guides and advances the advancing direction of the drilling part for drilling at least one of the buccal (B) and lingual (L) and occlusal side (O) of the at least one tooth, or the gingiva, and the drilling drill. The induction bushing 40 for limiting the depth includes a buried procedure 30. For reference, the applicant's guide template 10 is characterized by consisting of two layers of the first thermoplastic sheet layer in close contact with the teeth and the second thermoplastic sheet layer bonded to the outside of the first thermoplastic sheet layer.

Here, the support 20 refers to a part that plays a role of supporting and fixing the entire guide template 10 at a predetermined position in the oral cavity. Since the guide template 10 is made of a gingival with the oral cavity as a template and a first / second thermoplastic sheet which is tightly wrapped while covering the appropriate number of teeth, the support 20 has the same appearance as the teeth or gingiva. The shaped cavity is formed. Thus, when the cavity is fitted to the teeth of the corresponding shape, the support 20 wraps the buccal side B and the lingual L and the occlusal side O, or the corresponding gingiva, of the tooth, thereby providing a guide template 10. ) Is fixed in the premises.

In addition, the surgical part 30 is a part in which an implant surgery is performed (a tooth missing part), and instead of a cavity for mounting the guide template 10, an induction bushing 40 for guiding the progress of a drill for drilling is provided. Landfill is installed, one guide bushing 40 is provided for each surgical site. That is, the inner diameter of each guide bushing 40 has a size corresponding to the outer diameter of the drill for drilling to be used for each surgical site to guide the drill to proceed in the correct direction without shaking. In addition, if a stepped portion is formed below the inner circumferential surface of the induction bushing 40 and a drill having a corresponding induction part is used, the drill depth is limited to enter only a predetermined depth, so that the drilling depth may be controlled without a separate scale measurement. .

However, when drilling the alveolar bone for the implant procedure, if the fixture diameter of the implant is large, at least two stages should be first drilled using a small diameter drill first, and then a drill adapted to the final diameter should be used. For this purpose, a small diameter auxiliary bushing (for primary hole) provided at one or both ends of a bar-shaped auxiliary tool is inserted into the induction bushing, and the drill is carried out with the other hand while holding the auxiliary device with one hand. .

However, if the auxiliary device is not held by hand, the auxiliary bushing may rotate due to the rotation of the drill, and in order to prevent this, the auxiliary bushing may be drilled with only one hand to hold it. There are aspects that are hard to work with correctly. Furthermore, there is a risk of accidentally injuring the patient's mouth when drilling, and additional personnel are required to hold the auxiliary bushing.

In addition, repeated use of the assistive device wears out the inner circumferential surface of the auxiliary bushing, resulting in a gap between the drill and the drill, which may result in inaccurate drilling.However, it is almost impossible to visually check the condition of the assistive device. Even if you need a separate gauge because it is inconvenient in many ways.

On the other hand, even in the precision guided surgery using the guide template, the selection and guidance of implant surgery, surgical instruments and implants still guided the numerical information about the surgery and the diameter of the drill and the implant through the printed output as it was in the conventional surgery. .

Referencing the printed output impedes the physician's ability to concentrate and causes surgical errors due to the inconvenience of alternating the oral tissue and the output, which is the actual target to be focused, and prevents the proper operation of precision guided surgery. It became a factor. In addition, even if the surgical assistant outputs the surgical guide output instead, it may be mistransmitted during the information transmission, and additionally, manpower is required.

The present invention further improves the precision guided surgery using the guide template, so that even when using the auxiliary bushing, it is possible to safely and accurately perform the implant surgery with two hands by not having to hold the auxiliary device of the auxiliary bushing with one hand. It is an object of the present invention to provide an induction bushing assembly for the precise treatment of dental implants that do not require the checking of the aids of the patient.

In addition, the present invention is another object to allow the implant surgery to proceed in a concentrated manner by displaying the surgical information about the implant surgery or the diameter of the drill and the implant on the guide bushing.

The induction bushing assembly according to the present invention is cut in a direction orthogonal to the first cutting surface such that at least one first cutting surface is cut along the longitudinal direction with respect to the hollow cylindrical body and upper and lower jaws are respectively formed along the width direction.

According to one embodiment of the present invention, the inner bushing may further include a gripping portion provided at the end of the handle portion, the gripping portion may be a concave gripping surface is formed as a circular.

In addition, a through hole may be formed in the center of the grip portion to which the safe string may be bundled.

The inner surface of the inner bushing may have a circular or polygonal protruding figure indicating an implant surgery method, or the through hole may have a circular or polygonal shape indicating an implant surgery method.

In addition, an intaglio figure corresponding to the length of the drill to be used during the implant surgery may be formed on the upper surface of the guide bushing. In this case, the surface of the drill to be used during the implant surgery also corresponds to its length. It may be desirable for a number of figures to be displayed.

Meanwhile, at least one of the induction bushing and the inner bushing may have a color indicating the diameter of the drill to be used.

In addition, a metal inner tube may be inserted into the inner circumferential surface of the induction bushing or the inner bushing, and an inner tube inserted into the induction bushing may have a slot corresponding to the slot of the induction bushing.

In addition, the upper surface of the handle portion may form a flat surface, and the lower surface thereof may preferably form a curved surface whose height decreases toward the holding portion, and further, the holding portion may be formed so that the upper surface thereof protrudes from the upper surface of the handle portion. have.

The present invention can provide a guide template in which the induction bushing assembly having the above configuration is embedded, the guide template is for maxillary use, the slot of the induction bushing toward the palatal side for the molar and the premolar and other teeth It is preferable to face toward the buccal surface.

2 is an exploded perspective view of the induction bushing assembly 100 according to the present invention, Figure 3 is an assembled perspective view of the induction bushing assembly 100, with reference to this will be described in detail the present invention.

As shown in the figure, the induction bushing assembly 100 of the present invention is an induction bushing 110 having a hollow cylindrical body 112 and the inner bushing to be inserted and coupled in close contact with the inner peripheral surface of the induction bushing 110 ( It consists of two parts.

First, if the reason why the induction bushing assembly 100 is composed of two parts, the induction bushing 110 and the inner bushing 150, if the diameter of the hole to be drilled during the implant surgery is large, at least two steps This is because dividing perforation work should be performed to reduce heat generation during perforation of the alveolar bone and facilitate perforation without difficulty.

That is, the inner diameter of the guide bushing 110 corresponds to the diameter of the hole to be finally made in the alveolar bone. When the inner diameter of the guide bushing 110 is larger than a predetermined level, the inner bushing is drilled at a time. If the patient's body and the drill will be overwhelmed and the drilling work will be difficult. Therefore, it is preferable to proceed with the preliminary or primary drilling operation with a diameter smaller than the final diameter, and for this purpose, the inner bushing 150 having a smaller inner diameter while being detachably coupled to the induction bushing 110 is used. It is an additional configuration.

When the induction bushing assembly 100 consisting of two components, the induction bushing 110 and the inner bushing 150 is applied to the guide template 10 described above, the inner bushing 150 is inserted into the induction bushing 110. After the first drilling is performed, the inner bushing 150 is removed and the drilling work is finished by using a larger diameter drill.

Returning to the description of the present invention, the configuration of the induction bushing assembly 100 will be described in detail.

The induction bushing 110 is made on the basis of the hollow cylindrical body 112 and cut out a portion of the cylindrical body 112. Here, it is necessary to note that cutting a portion of the cylindrical body 112 does not intrude to the inner circumferential surface, but cuts a portion within the thickness of the hollow cylindrical body 112.

The cut surface can be described by dividing the first cut surface 114 and the second cut surface 116 based on the purpose and direction of cutting.

The first cut surface 114 is a surface cut along the longitudinal direction (height direction) of the body 112 of the induction bushing 110, and at least one or more surfaces thereof are formed. 2 and 3, two first cutting surfaces 114 are formed in parallel to each other, but are not necessarily limited to the illustrated form. The first cutting surface 114 serves to prevent the induction bushing 110 from rotating together in the guide template 10 by the rotation of the drill. Also, the first cutting surface 114 enters the space between the narrow teeth so that the induction bushing 110 body ( It also serves to reduce the width of 112).

The second cutting surface 116 is formed along a width direction perpendicular to the longitudinal direction, and is a surface for cutting a middle portion of the body 112 of the induction bushing 110 so that a step is formed at each of the upper and lower sides thereof. Is made. The second cut surface 116 is arranged in the direction perpendicular to the first cut surface 114, while making a stepped upper and lower, respectively, the second cut surface 116 is a guide template (induction bushing 110) in the longitudinal direction ( 10) to prevent the separation and separation.

In addition, the body 112 of the induction bushing 110 is formed with a slot 118 for longitudinally cutting the second cut surface 116 to penetrate the inner circumferential surface thereof. In the embodiment shown in FIGS. 2 and 3, two second cut surfaces 116 are formed to be perpendicular to and parallel to the first cut surface 114, and the slot 118 is either the second cut surface 116. It is formed long along the longitudinal center to cut the upper step of the). In the illustrated embodiment, the slot 118 is formed to the lower stepped boundary surface of the second cut surface 116, the length of the slot 118 to be appropriately designed with the handle portion 154 of the inner bushing 150 to be described later. Can be.

The inner bushing 150 has a hollow cylindrical body 152 inserted into the inner circumferential surface of the induction bushing 110, and the induction bushing 110 and the body 112 have a slot 118 of the induction bushing 110. A handle portion 154 extending to protrude to the outside is provided. In addition, an end portion of the handle portion 154 is provided with a grip portion 156 for holding with a finger.

The inner diameter of the body 152 of the inner bushing 150 corresponds to the inner diameter of the induction bushing 110, and the inner bushing 150 for the induction bushing 110 is held by the grip portion 156 of the end of the handle portion 154. ) To combine and disassemble At this time, the gripping portion 156 is circular, the gripping surface 158 is formed to be concave so that the tip of the thumb can be comfortably in close contact.

In addition, a through hole 160 may be formed at the center of the gripping portion 156. A small inner bushing 150 is implanted into the neck during the implant surgery by tying a safety string (safety seal) to the through hole 160. When an accident occurs, the inner bushing 150 may be safely collected using a safe string.

In addition, in the illustrated embodiment, the width of the handle portion 154 is made smaller than the width of the slot 118 to allow the inner bushing 150 to rotate slightly, which is an angle at which the grip portion 156 can be easily caught. It can be turned to. However, it is also possible to equalize the width of each other such that the handles 154 fit snugly in the slot 118.

In addition, as shown in FIG. 4, an embodiment in which the gripping portion 156 is narrow and elongated in accordance with the mesiodistal direction of the tooth, rather than circular, to reduce foreign body feeling in the oral cavity is also possible.

As such, the induction bushing assembly 100 of the present invention is easy to use because the inner bushing 150 having the handle portion 154 can be easily coupled to and separated from the induction bushing 110, and the inner bushing Since the handle portion 154 of the 150 is caught in the slot 118 and does not rotate during the drilling operation, there is no need to hold and work by hand. In addition, since the inner bushing 150 may be manufactured inexpensively by injection molding, there is no burden of discarding it after a single use, and therefore, there is a convenience in that it is not necessary to care for tolerance management by repeated use.

On the other hand, the induction bushing assembly 100 of the present invention by providing a variety of implant surgical information to the induction bushing 110 and the inner bushing 150 in a simple manner, the conventional uncomfortable and error-prone risk of referring to the printed output You can improve your approach.

First, information about the implant surgery method may be provided through the inner bushing 150. In this case, it is necessary to exclude the information about the implant surgical method as the character information, because the size of the guided bushing assembly 100 is very small because there is little character readability.

 Accordingly, the present invention considered a method of providing information about the implant surgery method in the form of a figure. 6 is a view showing an example of a figure indicating an implant surgery method, a circular designating a simple puncture surgery, a square specifying a bone graft surgery, a rhombus specifying a maxillary sinus elevation surgery, a bone transplant and a maxillary sinus elevation surgery It is possible to accurately convey the information about the implant surgery method with only four shapes of hexagons. For example, the inner bushing 150 of FIGS. 5A and 5B is shown in a hexagonal shape, which confirms that a complex surgery for bone graft and maxillary sinus elevation should be performed.

5A and 5B show two embodiments in which the figure specifying the above implant surgery method is displayed on the inner bushing 150, and FIG. 5A shows the implant surgery method on the upper surface of the body 152 of the inner bushing 150. FIG. 5B illustrates an embodiment in which the shape of the through hole 160 of the grip portion 156 is in the form of a circle or a polygon indicating an implant surgery method. .

Therefore, the operator of the implant surgery can accurately grasp information about the implant surgery method by confirming the figure represented on the inner bushing 150.

In addition, the guide bushing 110 may also provide information regarding the length of the drill to be used as one of the information required for the implant surgery. The length information of the drill is also represented as a figure, not a letter. As shown in FIG. 7, the length information of the drill may be provided in the form of a negative figure 120 (circular in the illustrated embodiment) on the upper surface of the induction bushing 110. It is provided in numbers.

The body surface of the implant surgical drill (DR) provided by the applicant is shown from one to five circular figures corresponding to the drill length of a total of five steps. Therefore, the operator of the implant surgery may proceed in a simple manner to select the drill (DR) corresponding to the number of the intaglio 120 provided on the upper surface of the guide bushing (110).

Here, even if the figure corresponding to the body surface of the implant surgical drill (DR) is not displayed, in the case of a drill set provided as a suit, it will not be difficult to select the corresponding drill according to the step-by-step length order, Therefore, it may be possible to omit the figure displayed on the body surface of the drill DR.

In addition, although the embodiment of the present invention expresses the length information of the drill in the intaglio graphic 120, the intaglio is represented by the embossed graphic or the printed form because only the intaglio is formed because the convenience of processing and the risk of damage are small. Of course it is also possible.

In addition, the induction bushing assembly 100 of the present invention may impart color information to each of the induction bushing 110 and the inner bushing 150 about the diameter of the drill to be used in the implant surgery. FIG. 8 is a view summarizing an embodiment of a color indicating a diameter of a drill to be used during implant surgery.

As shown in Fig. 8, the colors for designating the diameter of the drill are six colors of black (B1), yellow (Y), white (W), red (R), blue (B), and green (G). Colors can be sequentially assigned to diameters corresponding to drills of 1.8, 2.3, 2.8, 3.3, 3.8, 4.3mm, correspondingly the colors corresponding to their diameters for the induction bushing 110 and the inner bushing 150 Can provide information on the diameter of the drill to be used.

The diameter of the implant surgical drill provided as a suit is densely arranged at intervals of about 0.5 mm as summarized above, so that the drill can be accurately inserted into the guide bushing 110 or the inner bushing 150. Because of the difficulty, it is quite convenient to know the diameter of the drill simply by color, without a separate instrument for measuring the diameter.

In addition, since the inner diameter of the induction bushing 110 is the final diameter, the diameter information of the drill for the induction bushing 110 may be used as the diameter information of the implant. This is because the diameter of the drill and the diameter of the implant correspond to each other through a tolerance relationship, so that a suitable diameter of the implant to be placed in a drilled position with a specific diameter of drill is necessarily determined as one.

9 is a cross-sectional perspective view showing an embodiment in which an inner tube 122 made of a metal is inserted into an inner circumferential surface of the induction bushing 110. 9 illustrates a case in which the induction bushing 110 and the inner bushing 150 are manufactured by injection molding using medical engineering plastics for mass production and manufacturing cost reduction, and the induction bushing having a large diameter and a large friction area is manufactured. The inner circumferential surface of the 110 is reinforced by using an inner tube 122 made of metal.

Here, although not shown, it is also possible to reinforce the inner circumferential surface of the inner bushing 150 with a metal inner tube.

In addition, when the inner tube 122 is applied to the induction bushing 110, a slot 124 corresponding to the slot 118 of the induction bushing 110 should be formed in the inner tube 122. The inner tube 122 may be fixed to the induction bushing 110 or the inner bushing 150 separately by bonding or fitting, and, when manufactured by injection molding, the inner tube 122 in the injection step through insert injection molding. May be provided integrally.

10 and 11 are diagrams of guide templates 1000 and 1000 ′ to which the induction bushing assembly 100 of the present invention is applied, and FIG. 10 shows an embodiment of the maxillary guide template 1000, and FIG. 11 shows one embodiment of the mandibular guide template 1000 ′.

The difference between the maxillary and mandibular guide templates (1000, 1000 ') is that in the case of the maxillary guide template (1000), the slots (118) and the inner bushing (150) of the guide bushing (110) for the molar and premolars While the handle 154 faces the palatal side and toward the buccal side for the rest of the tooth position, in the case of the mandibular guide template 1000 ′, it is disposed to face the buccal side for all the tooth positions. Arranging the induction bushing assembly 100 in this manner minimizes interference between the handle portion 154 and the grip portion 156 with oral tissues such as the tongue or cheek, and prevents the patient from feeling discomfort and causing nausea. This is to help the implant surgery go smoothly.

Here, even when the handle 154 of the slot 118 and the inner bushing 150 of the induction bushing 110 is disposed toward the buccal side, the strength of the handle 154 and the grip 156 pressing the inside of the gum or the ball. It is more desirable to reduce the

To this end, the upper surface of the handle 154 forms a flat surface while the lower surface of the handle 154 toward the grip portion 156 to reduce the amount of interference by the handle portion 154 to press the gum and the inside of the ball can be reduced. have.

In addition, the upper surface of the grip portion 156 is formed so as to protrude a little more upward with respect to the upper surface of the handle portion 154, it is also preferable that the grip portion 156 is located close to the inner center of the ball where the ball can be most flexible stretch. Do.

The present invention is useful for use in the application of precision guided implant surgery using a guide template that is a surgical guide fixture.
