Embodiment Construction

[0053] As shown in the figure, an implant system based on titanium-zirconium alloy includes: an implant 1, an artificial tooth abutment 2 and a central bolt 3; The body insertion section 22; the crown connection section 21 is a truncated cone, and the taper of the truncated cone is 2-10°, preferably 3°. The crown connection section 21 is a truncated cone with an elliptical cross section, which can effectively increase the tightness between the artificial tooth abutment 2 and the crown, and prevent the crown from loosening.

[0054] Such as Figure 5 As shown, an intermediate gingival section 24 is provided between the crown connection section 21 and the implant insertion section 22, and the intermediate gingival section 24 includes a coaxially arranged gingival cone 142 and simulates the natural gingival shape for aesthetic restoration. According to the asymmetrical conical surface 241 of Asians, the height of the middle transgingival segment 24 does not exceed 6mm according ...

Abstract

The invention discloses an implant system based on titanium-zirconium alloys. The implant system comprises an implant, an artificial tooth base table and a center screw, two ends of the artificial tooth base table are provided with a dental crown connecting section and an implant inserting section respectively, the implant inserting section comprises a first frustum, a plum blossom-shaped column and a second frustum, the dental crown connecting section is connected with a large-diameter end of the first frustum, a small-diameter end of the first frustum is connected with one end of the plum blossom-shaped column, and the other end of the plum blossom-shaped column is connected with a large-diameter end of the second frustum. According to the implant system based on the titanium-zirconium alloys, the implant is of a double-threaded structure of a primary thread and a secondary thread, alveolar bone damage can be effectively reduced, generated cutting resistance is small, and the implant system effectively solves the problems of bone burn, stress concentration, micro-cracks of notching positions and the like.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to an implant system based on a titanium-zirconium alloy. Background technique [0002] With the continuous development of oral implant technology, the "artificial implant" technology has gradually matured and stabilized. Artificial dental implants are to first place a titanium artificial tooth root with high biocompatibility into the alveolar for fixation and suture, and after several months to wait for the artificial tooth root to be firmly connected to the bone in the alveolar, the subsequent denture installation is carried out. The artificial tooth root of "artificial implant" is directly connected to the bone, which can provide better supporting force and is popular for chewing hard food. Among them, the success rate of artificial tooth implants and the overall natural and harmonious appearance are two issues that people are most concerned about. [0003] The...
