Bending large-angle base station device

Abstract

The invention relates to a bending large-angle base station device which is applied to the oral implantation recovery, and provides a base station device which is novel and can implant a common implant at an appropriate position on the side surface of the upper jaw for recovery without sinus maxillaries lifting surgery for solving the defects that in the implantation process when the bone weight of the side surface of the upper jaw is not enough, complicated bone increasing or sinus maxillaries lifting surgery needs to be done, the surgery complicacy is high, the surgical trauma is large, the surgery risk is high, the surgery cost is high and the like. A bending base station seat (3) which is inserted into the implant (1) and a dental corona base station (6) form a dental corona supporting system; the dental corona is arranged on the base station (6), is connected with the base station seat (3) through a conical surface (12) and an octagonal cylindrical surface (13), and fastened by a fastening bolt (2); the connection between the dental corona base station (6) and the base station seat (3) is also realized by a conical surface (10) and an octagonal cylindrical surface (9), and the fastening is realized by a fastening bolt (7); and consequently, excellent sealing performance, anti-rotation performance and circumference directional performance can be achieved.

Description

Technical field: [0001] The invention relates to an oral medical appliance, in particular to a curved large-angle abutment device for oral implant restoration. Background technique: [0002] In the 1960s, the University of Gothenburg in Sweden The professor conducted research on oral implant materials and bone-implant interface, created the "osseointegration" theory of titanium, and laid a theoretical foundation for the application of modern oral implantology. Dental implant application technology is the most important part of modern oral implantology. The widespread development and application of oral implant dentures have solved a series of aesthetic and functional problems caused by clinical tooth loss. [0003] In my country, with the development of science and technology and the improvement of people's living standards, oral implant technology has been rapidly developed and widely used. Oral implants include intraosseous implants, connecting abutments and artificial ...

AI Technical Summary

Problems solved by technology

The surgical technique requirements for oral implants are relatively strict, especially when the implant surgery is performed on the side of the maxilla where there is insufficient bone mass, the alveolar bone atrophy will be caused after tooth loss, so that the implant cannot be directly implanted due to insufficient bone mass. Performing more complicated bone augmentation or maxillary sinus lifting surgery will increase the pain of the patient, increase the risk of surgery, prolong the time of restoration treatment, and increase the cost of surgery, which is one of the difficulties in the current maxillary posterior implant technology
