Spline-tooth type oral implanting device

Abstract

The invention relates to a defected-tooth implanting or restoring technology, in particular to a spline-tooth type oral implanting device comprising an implanting body, a base station and fastening bolts. External threads are arranged on the implanting body, and stepped cylindrical-surface inner cavity is arranged in the implanting body; the lower end of the base station is provided with a tubularconnecting handle which is connected with the implanting body. The spline-tooth type oral implanting device is characterized in that the connecting handle and an inner cylindrical surface through which the implanting body and the base station are connected are provided with matchable spline teeth, and the lower part of the implanting body is provided with a longitudinal cut groove is deeper thanthe threads. The spline-tooth type oral implanting device can be operated conveniently and can be well combined with the alveolar bone; the implanting body has good stability and can bear larger torque without being internally deformed; the base station and the implanting body can be adjusted in angle and can be connected in high precision; and the spline-tooth type oral implanting device can reduce the bone resorption.

Description

Technical field: [0001] The invention relates to the technical field of implantation or restoration after tooth defect, in particular to a key tooth type oral implantation device. 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. the main part. The widespread development and application of oral implant dentures have solved a series of aesthetic and functional problems caused by clinical tooth loss. [0003] However, during the implantation process, due to the narrow space for missing teeth, the surgical operation is difficult. Due to factors such as the structure of the implant itself, bone quality and surgery, the initial stability after implantation is poor, and the cooperation with the upper structure is also not ideal...

AI Technical Summary

Problems solved by technology

[0003] However, during the implantation process, due to the narrow space for missing teeth, the surgical operation is difficult. Due to factors such as the structure of the implant itself, bone quality and surgery, the initial stability after implantation is poor, and the cooperation with the upper structure is also not ideal. place

Three problems are often encountered. First, because the implant is screw-shaped and screwed into the implant, during the implant implantation process and subsequent repairs, the implant body will undergo local deformation due to torque, which makes the abutment Difficulty in placing the abutment and the implant may cause loose or empty position; second, the degree of bone extrusion is difficult to grasp, and there may be excessive extrusion or no extrusion and gaps; third, implant restoration Bone resorption is prone to occur later, which may lead to unsatisfactory implant repair effect or repair failure
