Description

A method for manufacturing an implant fixture and an implant fixture thereby,

The present invention relates to a method of manufacturing an implant fixture, and more particularly, to a method of manufacturing an implant fixture, and more particularly to a method of manufacturing an implant fixture including an implant fixture including a lower fixture constituting a body of a gingival section and an upper joint, And an implant fixture by the method.

Generally, a tooth implant is a fixture that is placed in or on the jawbone for supporting a prosthesis for restoration of a missing tooth. Dental implants are often referred to as artificial teeth or third teeth that are placed in the gums and gums.

The implants are implanted into the jawbone, which is enlarged to allow the implant to be sufficiently wrapped, through additional operations such as bone grafting and osseointegration on the tooth defects or the jawbone of the tooth extraction site. It is a dental treatment technique that restores function.

After the osseointegration, which is a morphological, physiological and direct coupling between the jawbone and the surface of the implanted body, which is maintained normal function, is performed, the bone is subjected to a bone remodeling process of the peri-implant jaw.

These implants are generally used in the form of a screw-shaped bony implant, and the upper structure of the implant (abutment) is screwed.

As described above, in the conventional method of fastening with the screw fastening method, the screw is loosened and the screw is broken.

In addition, since a tooth has to be punctured to fix the tooth to the implant, the aesthetic effect and durability are weakened, and the tooth (crown or metal) should be destroyed when the problem occurs after implant placement.

The conventional method of fastening with the screw fastening method inconvenient to the patient due to the additional cost, time spent in the additional treatment and operation, inconvenience that the adhesive should be adhered in the oral cavity when the crown and the combined structure are combined, Inflammation and periodontitis are often caused by residual adhesives.

4 is a view of the upper joint 200 to which the crown 300 is coupled through the upper joint and the crown joining step (S9).

Hereinafter, an implant fixture manufactured through the above-described manufacturing method will be described.

Referring to FIGS. 1 and 2, the implant fixture of the present invention is composed of a lower fixture 100, an upper fixture 200, and a crown 300.

3 is a view of the lower fixture 100. The lower fixture 100 includes a gingival formation part 110 and an upper joint part 120. As shown in FIG.

First, the gingival locating portion 110 is formed in a cylindrical shape, which is embedded in the alveolar bone (gum) of the tooth 10, and has threads on the outer peripheral surface.

The gingival formation part 110 is further formed with a cutting groove 111 and the cutting groove 111 is formed in a spiral shape along the longitudinal direction of the gingival formation part 110. A plurality of the cutting grooves 111 may be formed in the circumferential direction of the gingival perforation 110. However, the gingival perforation 110 may be formed in four spiral shapes along the longitudinal direction of the gingival perforation 110, To improve the osseointegration and cutting force of the gums.

The lower fixture 100 is positioned on the upper portion of the gingertip 110 and is coupled to the upper fixture 200.

The upper engaging portion 120 includes a first engaging portion 121 and a reverse engaging protrusion 122.

The first fastening part 121 is formed to be fastened to the second fastening part 220 of the upper fastening body 200 and is formed as a groove along the upper circumference of the upper fastening part 120 as shown in FIG. .

The dislocation reversing protruding portion 122 is formed on one side and the other side (both sides) of the upper engaging portion 120 and is protruded in a pointed shape to prevent it from being detached in a reverse direction embedded in the alveolar bone (gums).

5 is an enlarged view of the upper joining part 120 and shows a state in which the upper joining part 200 having the crown 300 coupled to the upper joining part 120 is engaged.

5, the dislocation-removing protruding portion 122 is a portion that is placed on the gum 11 and grips the soft tissue of the gum to prevent the lower fixture 100 from separating from the gum 11 as indicated by the arrow The giver plays a role. That is, by adding the dislocation reversing protruding portion 122 to the upper engaging portion 120, the lower fixture 100 can be stably placed on the gum during the implant procedure.

The upper assembly 200 includes an upper coupling portion 210 to be coupled to the upper coupling portion 120 of the lower fixture 100. The crown 300 is coupled to the outer circumferential surface of the upper assembly 200.

The second fastening part 220 is formed in the shape of a ball to be fastened to the first fastening part 121 so that the upper fastening body 200 is fixed when fastened to the lower fixture 100.

FIGS. 13 and 14 relate to an implant operation photograph using the lower fixture 100 and the upper joint 200.

Fig. 13 (a) is a photograph of the lower fixture 100, and Fig. 13 (b) is a photograph showing a state where the lower fixture 100 is placed on the tooth 10. Fig. The lower fixture 100 manufactured through the lower fixture manufacturing step S1 and the cutting groove manufacturing step S2 is placed in the tooth 10 as shown in FIG.

As shown in FIG. 14 (a), when the lower fixture 100 is placed in the tooth 10 as shown in FIG. 13 (b), the crown 300 manufactured through the upper assembly and the crown- The upper joint 200 is coupled to the upper joint 220 of the lower fixture 100 as shown in FIG. 14 (b), and the implant procedure is completed.

Fig. 15 is a diagram of two implant procedures. As shown in Fig. 15,

There is a problem that it is difficult to join the crown 300 after the upper assembly 200 is fastened when the lower fixture 100 is installed at an oblique angle without being dented. Therefore, after the crown 300 is previously coupled to the upper joint 200, the crown 300 of the two upper joints 200 to which the crown 300 is coupled is abutted, and then the two lower fixtures 100 to the upper joining portion 120 of the apparatus.

It is needless to say that the upper coupling part 210 of the upper coupling part 200, which is a part to be coupled with the upper coupling part 120, has a space enough to accommodate the inclined lower fixing device 100.

The lower fixture 100 having the upper joint part 120 and the gingery insert part 110 coupled to each other is first placed in the gum and the upper joint part 110 coupled to the crown 300, The implant 200 is connected to the upper joint 120 of the lower fixture 100 to complete the implant procedure. In the case of implant treatment through the implant fixture manufactured through the present invention, it is possible to minimize the damage of the gum by shortening the procedure and time.

 Also, there is an effect of preventing the lower fixture 100, which is placed on the gum due to an external impact during the procedure or after the procedure, from being released to the outside through the dislocation releasing protrusion 122 of the lower fixture 100.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be clear to those who have.
