Abstract

PURPOSE: A manufacturing method of an anterior implant abutment is provided to install a bridge after removing neighboring natural tooth and to stably process and install artificial tooth. CONSTITUTION: A manufacturing method of an anterior implant abutment includes the following steps. A polygonal protrusion (550) processed in a fixture and a coupling part processed in an abutment (100) are coupled with each other. A screw (300) is drawn through a penetration part (700), and the abutment and the fixture are fixed. The fixed abutment and the fixture maintain the fixed state thereof without shaking by the tightening force of a screw and the coupling force between the polygonal protrusion and the coupling part. Through the penetration part, the screw is coupled to the coupling part processed in the abutment. The fixture is fixed by the coupling part in the abutment and the screw.

Description

Production method of an implant implant abutment

Implant Abutments for Artificial Teeth

Implant is a cutting-edge procedure that restores the original function of the tooth by connecting the artificial tooth by fusion of the artificial tooth made of titanium, ceramic, and other materials in the alveolar bone to replace the root of the missing tooth.

In recent years, the implantation procedure has been performed by placing an implant fixture in an alveolar bone, applying ceramic material to an implant abutment, and bonding it to an implantation method.

Hereinafter, a conventional implant abutment will be described with reference to the accompanying drawings.

As shown in Fig. 1, a conventional implant includes a fixture 1 embedded in an alveolar bone, an abutment 2 seated on the fixture 1, a fixture 1, and an abutment. (2) is configured to include a screw (3) for fastening.

As shown in FIG. 2, when the fixture 1 and the abutment 2 are fastened by the screw 3, the fixture 1 and the abutment 2 are fixedly coupled to the fixture 1, and the fixture 1 and the abutment 2 are fixed. Again, it is not shaken by the screw (3) to maintain a firmly fixed state.

In general, the patient perceives that the initial treatment cost is slightly higher, but the treatment is considered to mean aesthetically stable treatment without damaging the adjacent adjacent teeth, but in reality, when the tooth is extracted, the existing implant abutment The process is to install the ceramic from the top to the bottom, so that the aesthetic and self-cleaning problems are removed due to problems such as pass, undercut, and natural tooth structure. By unstable processing, the patient's adjacent tooth damage, aesthetic damage, and economic burdens increase.

In order to solve the above problems,

See drawing 3

Process the front and end surfaces in the first abutment (hereinafter referred to as the abutment 100), and form the through portion 103 inside the processed front and end surfaces, and through the inside of the through portion 103 A through portion 104 having a width narrower than that of the portion 103 is formed. A middle portion (100-1) is formed on the abutment (100), and a through portion is formed in the middle portion (100-1). To form a 700, a through-hole 701 narrowing the width is formed in the formed through-hole 700, polygonal fastening groove 501 is formed at the bottom of the through-hole 701, the fixture ( 2) to form a polygonal projection 500, and to form a screw hole 702 on the upper and lower surfaces of the polygonal projection 500, and a screw groove (described below abutment 200) Forming 202.

The effect of the present invention is to reduce the preservation and ease of self-cleaning, extraction of aesthetic damage and economic loss of adjacent natural teeth extracted.

See drawing (3)

The through part 700 formed on the middle and the end surface 100-1 is coupled to the protrusion 500 of the polygon processed on the fixture 2 and the fastening part 501 processed on the abutment 100. Screw 300 is introduced through the abutment 100 and the fixture (2) is fixed

The combined abutment 100 and the fixture (2) of the abutment 100, the polygonal fastening portion 501 and the fixation formed in the through portion 701 inside the end face (100-1) Due to the coupling of the protrusions 500 of the polygon formed in the chur (2) and the tightening of the screw (300) is not shaken by the external force to maintain a firmly fixed state

The screw 400 is fastened to the fastening part 201 processed in the abutment 200 through the through part 103 formed in the fastened abutment 100,

The fixture 2 is fixed by the fastening portion of the abutment 100 and the screw 400, and the abutment 200 is also firmly not shaken by external force due to the tightening of the screw 400. It will remain fixed and complete one implant.

The assembly method of the abutment 100 and the abutment 200 may be finished in a screw method or a seman type.
