Embodiment Construction

[0050]As shown in the figure, a straight abutment implant system based on titanium-zirconium alloy includes: an implant 1, an artificial tooth abutment 2 and a central bolt 3; the two ends of the artificial tooth abutment 2 are crown connecting sections respectively 21 and the implant insertion section 22; the crown connecting 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.

[0051] The implant insertion section 22 is a first conical frustum 221, a quincunx column 222 and a second conical frustum 223 coaxially connected, and the crown connection section 21 is connected to the large diameter end of the first conical frustum 221, the The small-diameter end of the first truncated cone 221 is connected with one end o...

Abstract

The invention discloses a straight abutment implant system based on titanium zirconium alloy. The straight abutment implant system comprises an implant, an artificial tooth abutment and a central bolt, wherein the two ends of the artificial tooth abutment serve as a dental crown connection section and an implant insert section; the implant insert section is formed by a first frustum, a quincunx column and a second frustum which are coaxially connected; the dental crown connection section is connected with the large-diameter end of the first frustum, the small-diameter end of the first frustum is connected with one end of the quincunx column, and the other end of the quincunx column is connected with the large-diameter end of the second frustum. According to the straight abutment implant system based on the titanium zirconium alloy disclosed by the invention, the implant is of a dual-thread structure that a main thread and a secondary thread are combined to effectively reduce harm to alveolar bone; as generated cutting resistance is small, the problems of bone burn, stress concentration, micro crack initiation at grooved positions and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to a titanium-zirconium alloy-based straight abutment implant system. 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. ...
