Description

  The present invention relates to an abutment material for a custom-made implant and a jig for processing a tooth, and more specifically, in a manufacturing process of a custom-made abutment that requires precision, a processing jig installed in a processing machine. Abutment material and teeth for bespoke implants that allow the abutment material to be connected even when it is difficult to ensure sufficient space between the lower part and the main body of the processing machine, and to further fix this It relates to a jig for machining.

  In general, an implant is an artificial tooth that is implanted into the alveolar bone when a tooth loss or loss occurs. Implants can be operated on only the missing part without damaging adjacent teeth, providing rapid restoration of tooth functionality and morphological aesthetics, accurate pronunciation, and overall oral health It has the advantages of

  Such an implant includes a fixed body (Fixture) that is normally planted in a gum, an abutment that is fixed to the fixed body by a screw and supports the implant, and an artificial tooth that is fixed on the abutment It is comprised with the crown (Crown) which comprises the external shape.

  Here, the abutment (hereinafter referred to as a workpiece) transmits a load transmitted from the crown to the fixed body, and accordingly, plays a role of transmitting the load to the jawbone. For this purpose, the workpiece needs to be manufactured considering the size, pattern and contour of the artificial teeth. In addition to this, it is possible to engage with peripheral teeth and counter teeth (upper teeth or lower teeth), and individual teeth. It must be manufactured to reflect all of its characteristics, gum status and gum line.

  For this reason, recent implant processing objects tend to be preferred to be made according to each patient's teeth, rather than ready-made products supplied in a uniform size.

  On the other hand, conventionally, when fixing the abutment material for processing a custom-made abutment as described above to the processing jig, a method of clamping the outer diameter of the abutment material in a grip form has been adopted. .

  However, the conventional method as described above requires a long connection time in order to fix and connect the abutment material at an accurate position by connecting the outer diameter of the abutment material with a gripping processing jig. In addition, the position of the abutment material may change in the processing process, or the abutment material may be detached from the processing jig.

  In order to solve the above-described problems, the applicant of the present invention, as shown in FIG. 1, has made a custom-made abutment by processing a cylindrical body 100 and a body 100 formed integrally with one end of the body 100. A fixing part 200 that is used as a part for fixing the body 100 to a processing jig when manufacturing an attachment, a coupling part 300 that is formed at the other end of the body 100 and is connected to a fixed body that is planted in a gum, The fixing part 200 and the body 100 are formed between the connecting part 300 and the body 100 and the connecting part 300, and a connecting screw part 400 inserted into the fixing jig 200 for connecting to the processing jig. The fixing unit 200 includes a connecting groove 500 into which a connecting means for connecting to the fixed body is inserted, and the fixing unit 200 is tapered as it is farther from the body 100. Patent application No. 10-1093512 (Patent Document 1), which is a technique related to an abutment material 10 for implants, characterized in that it further includes a flat portion 210 for determining the position when it is connected to and received registration. I have been there.

  The technique described in Patent Document 1 described above easily inserts a material into an accurate position of a processing jig corresponding to the formation of the position determining plane part 210 in the fixing part 200 provided to be tapered. In addition to fixing, the fixing part 200 and the connecting screw part 400 formed inside the main body 100 are screwed with a fixing screw that penetrates the lower part of the processing jig to fix the material to the processing jig. This makes it possible to firmly fix the material.

  However, the technique described in Patent Document 1 is that the material is used as a processing jig when it is difficult to ensure a sufficient space between the lower part of the processing jig installed in the processing machine and the main body of the processing machine. There arises a problem that a fixing screw for screwing cannot be screwed to the connecting screw portion.
