Description

The procedure method of implant and abutment using the same}

The present invention relates to a method of implantation, and more specifically, by being inserted into the jawbone where the lost tooth is located to artificially perform the dental function, it is very convenient compared to the conventional implant treatment, but the procedure time is innovative It relates to an implant abutment that can be shortened.

In the field of modern dentistry, the research on the method of restoring the function of the tooth lost by various causes is continuously conducted, and clinical trials are actively conducted accordingly.

Among them, the most commonly used method is the use of brass processing dentures (common people say they put it) that restores the function of lost teeth by using the surrounding teeth, or by using the surrounding teeth and gums simultaneously Local or total dentures (commonly known as partial or complete dentures) are used to replace missing teeth.

However, the crown denture had the disadvantage of eliminating the surrounding healthy teeth, and in the case of a large number of missing teeth, there was a limit in maintaining its function and withstanding occlusal pressure. Discomfort in the situation has been raised a lot.

Therefore, in order to solve the above problems, the implant procedure has recently been in the spotlight.

Such a conventional implant is a fixture that is screwed into the alveolar bone where the tooth is lost, and is coupled to the upper side of the fixture and used as a pillar for covering an artificial crown on the exterior. Abutment, the fixing screw (Abutment) and the abutment (Abutment) and the abutment is fixed in the oral cavity by the abutment and the same shape as the natural teeth and It consists of an artificial tooth that reproduces the function.

Briefly describing the conventional implant procedure, a fixture having a hexagonal protrusion on the top is embedded in the jawbone, and when the jawbone and the fixture are bonded to each other, the protrusion corresponds to the protrusion on the upper surface of the fixture. The arrangement of peripheral teeth and the attachment of the grooved cylindrical abutment and the fastening of the fixing screws to fix the fixture and the cylindrical abutment together Cylindrical abutments are tooth-shaped to fit the shape. The artificial tooth is then applied to the outside of the abutment to complete the procedure.

Unlike the conventional prosthesis or denture, the conventional implant as described above has the advantage of not damaging the surrounding dental tissue, the function or shape is similar to natural teeth, but has a relatively long life.

By the way, in the conventional implant procedure, the cylindrical abutment is performed every time the implant procedure is carried out while the cylindrical abutment is fixed to the fixture via the fixing screw. Because it must be used after the basic processing in the form of teeth, the implant procedure takes a very long time, and as the implant procedure takes a long time, the patient has to visit until the end of the procedure. there was.

Furthermore, the abutment installation angle is inevitable for the secondary processing in consideration of the relationship with the surrounding teeth (positioning state, shape, etc.) in the state where the abutment is processed based on the shape. In this case, both the protrusion of the fixture and the groove of the abutment form a polygon (usually a hexagonal structure), which rotates by 60 degrees when rotating from one side to the next, so that the abutment If you adjust the installation angle of, the problem is that the removal of the abutment will be excessive because it will be larger or smaller than the initial installation angle. Due to the problem, there was a fundamental problem that the abutment, which was preliminarily formed, could not be applied to the implant procedure.
On the other hand, a conventional abutment is a registered utility model publication No. 20-0345601 (a single tooth restoration abutment).

The present invention has been made to solve the above problems, and to provide an implant abutment that can minimize the amount of removal due to the reinstallation through precise rotation angle control and precise rotation angle control compared to the conventional implant procedure There is a purpose.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

1 and 2, an implant according to the present invention is composed of a fixture 10, a foundation molded abutment 20, a fixing screw 30, an artificial tooth 40.

The fixture 10 has a cylindrical shape as a whole, a spiral is formed on the circumferential surface so as to be fastened to the jawbone 1, and a hexagonal coupling protrusion 12 is integrally formed at the center of the top, and at the center of the interior. The screw opening hole 11 is formed on the inner circumferential surface and is formed on the inner circumferential surface, and is a support of a known metal material embedded in the alveolar bone, that is, the jaw bone 1, where the tooth is lost.

3 and 4, the basic abutment 20 is composed of the abutment body 21, the fixing screw insertion portion 22 and the coupling groove 23, the fixture 10 It is coupled to the upper side of the artificial tooth 40 is used as a pillar for covering the exterior. Here, the basic processing means pre-molded in the form of teeth.

The abutment body 21 includes a gum insertion portion 21a having a lower horn and a wider angle; Artificial tooth insertion portion 21b which is formed integrally on the gum insertion portion 21a, is located inward from the edge of the gum insertion portion 21a, and the circumferential surface is equidistant from the edge of the gum insertion portion 21a. It consists of.

In addition, the abutment body 21 is integrally formed with a fixing screw insertion part 22 penetrating up and down the inner center along a longitudinal direction, and a fixing screw 30 is inserted into the fixing screw insertion part 22. do.

In addition, the bottom surface of the gum insert 21a of the abutment body 21 is provided with a coupling groove 23 which is mutually coupled with the coupling protrusion 12 of the fixture 10.

The coupling groove 23, as mentioned above, is formed on the lower inner surface of the gum insertion portion 21a, it is in communication with the fixing screw insertion portion 22, the shape seen from the bottom 24 corner angle number It is shaped like a star with (i).

In the present embodiment, as shown in FIG. 3, the coupling groove 23 having 24 corner angles is illustrated and described. However, this is only one embodiment. Since the present invention can be variously modified in a form having 48 corner angles, it is not preferable to limit the analysis to this.

Furthermore, in the present embodiment, since the coupling protrusion 12 of the fixture 10 has a hexa (hexagonal) shape, the coupling groove 23 corresponding thereto is manufactured in the form of 24 corner angles. For example, when the coupling protrusion 12 has a square shape or a pentagon shape shape, the corresponding coupling groove 23 has a star shape having 16 or 20 corner angles. Since it will be manufactured as, it is not preferable to interpret only the embodiment.

On the other hand, between the fixing screw insertion portion 22 and the coupling groove 23 is formed a ring-shaped locking jaw 22a protruding inwardly, where the locking jaw 22a is excessively tightened of the fixing screw 30. This prevents the fixture 10 or the abutment 20 from being damaged.

According to the present embodiment, since the abutment 20 is basically processed in the form of a tooth, it is possible to drastically shorten the time of the preceding work (tooth shaving) compared to the conventional method, and thus the procedure is considerably convenient. In addition, in the state in which the coupling grooves 23 of the abutment 20, which is based on the coupling protrusion 12 of the fixture 10, are mutually coupled with each other, the basic machining is performed in consideration of the arrangement and shape of the peripheral teeth. Since the abutment 20 can be rotated little by little (by 30 degrees based on the number of 24 corners), the correct installation angle can be adjusted. It is possible to readjust the installation angle.

On the other hand, Figure 4 shows a side view of the abutment 20 in the implant according to the present invention, when viewed from the side of the front of the gum insertion portion (21a) relative to the fixing screw insertion portion 22 (in Figure 4 The left side) and the back side (corresponding to the right side in FIG. 4) are asymmetrical to each other, that is, the front side is formed relatively abundantly compared to the back side. And to prevent insertion between the artificial tooth (40).

The fixing screw 30 is a known fastening means.

In the present embodiment, the fixing screw 30 is inserted into the fixing screw insertion portion 22 of the abutment 20, and is fastened with the screw coupling hole 11 of the fixture 10 to the fixture 10 and Function to allow the abutment 20 to be mutually coupled.

The artificial tooth 40, as shown in Figure 5d, has an insertion groove 41 corresponding to the inner side of the bottom to be mutually coupled with the artificial tooth insertion portion 41 of the abutment 20, , The abutment 20 and the adhesive are connected to each other through the insertion groove 41.
