Bushing-type oral implanting device

Abstract

The invention relates to a defected-tooth implanting or restoring technology, in particular to a bushing-type oral implanting device which is characterized in that at least two grooves with openings on the upper ends are distributed on a cylindrical surface through which an implanting body is connected with a base station; the upper end of the base station is provided with lug bosses which are matched with the grooves; the combination length of the implanting body and a tubular connecting handle of the base station is nearly 1 / 2 or more of the length of the implanting body so that the implanting body can be embedded in shaped holes on the alveolar bone to shorten the operation time; the implanting body has good bone extruding effect, thus the early-stage stability and the later-stage osseointegration stability after the operation are improved, and the use effect after the healing is enhanced; the contact surface of the thread-type implanting body and the alveolar bone is enlarged, thusthe implanting body and the alveolar bone can be more firmly combined, and the implanting quality of the implanting body is improved; the base station and the implanting body are more tightly connected and are more firmly combined, thus the operation is more convenient; the bushing-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 lateral force with little or no inclination; the base station and the implanting body can be adjusted in angle and can be connected in high precision;and the bushing-type oral implanting device can inhibit 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 sleeve 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 edentulous space, the surgical operation is difficult, and the initial stability after implantation is poor due to factors such as the structure of the implant itself, bone quality, and surgery, which in turn affects the stability of osseointegration and repair e...

AI Technical Summary

Problems solved by technology

[0003] However, during the implantation process, due to the narrow edentulous space, the surgical operation is difficult, and the initial stability after implantation is poor due to factors such as the structure of the implant itself, bone quality, and surgery, which in turn affects the stability of osseointegration and repair effect in the later period. , three problems are often encountered. First, there is a contradiction between the accuracy requirements of the implant and the abutment, the processing cost, and the convenience of operation. High precision means high processing cost and poor operation convenience. If it is too low, there will be looseness or empty position between the abutment and the implant, which will have adverse effects on the restoration and future use. The third is that when the abutment and the superstructure bear a large lateral force or lateral component force, the joint plane of the abutment and the implant will appear local tiny gaps due to elastic deformation
