INSTRUCTIONS: [Technical Field] The present invention relates to a manual abutment tooth for a dental implant, and more particularly to a composite artificial abutment tooth. [Prior Art] Artificial implants refer to a dentist implanting a screw-shaped artificial root in the patient's optimal implant, and then assembling a manual abutment on the artificial root, and the artificial abutment The teeth are exposed to the gums = the crown is combined, and the artificial implant surgery is completed. After artificial hand implants, the chewing and speech function of the patient's mouth can be improved, and the aesthetics can be restored. The artificial abutment teeth are made of metal material (such as titanium alloy), but the metal is transparent. Poor, it will lead to the formation of black shadows in the middle of the denture after the crown is combined, although it will not cause the function of chewing and speech: but it will affect the beautiful function. According to this, the artificial abutment teeth are produced. Since the color of the ceramic material is similar to the actual tooth and the light transmittance is better than that of the metal, the ceramic (four) material has gradually replaced the metal (4) to make the artificial abutment tooth. However, it is customary to make artificial abutment teeth with ceramic materials, which still have the following defects that need immediate improvement in practical use: In the process of artificial dental implant surgery, due to the limited space of each dental implant (ie, The distance between the adjacent teeth of the implant should be combined with the artificial root (ie, the artificial joint △ sound, the artificial branch 13 low, the interface of the bottom of the artificial abutment tooth (on the rfaee) combined with the joint interface of the top of the human root (10) Heart (5)) 々 Therefore, the joint interface that causes the artificial abutment teeth to engage with the artificial roots is thick and limited, and this limitation will cause the problem that the artificial abutment teeth of the ceramics have a fracture in the case of a thickness less than 200938170. First, since the artificial root system is implanted in the alveolar bone of the human body, it is not easy to replace it, and the artificial abutment tooth made of the ceramic material has a hardness greater than that of the artificial root made of metal material. Therefore, when the artificial abutment tooth is coupled to the root of the human tooth, but the assembly or adjustment is improper, the artificial tooth root may have wear and tear. First, since the artificial abutment tooth and the artificial root are different f is made, so it is necessary to consider a lot of production conditions in the production, in order to maintain a certain combination of the two. The invention aims to provide a composite artificial abutment tooth, The utility model mainly aims to prevent the joint interface of the bottom of the artificial abutment from being broken. Another object of the present invention is to provide a composite artificial abutment tooth, which mainly avoids the abrasion of the artificial root after the assembly of the artificial abutment tooth. A further object of the present invention is to provide a composite artificial abutment tooth, which is capable of improving the bond between the artificial abutment tooth and the artificial root. The edge is that, in order to achieve the foregoing object, a retanning according to the present invention is provided.
