Pipe sleeve anti-rotary dentistry implant

Abstract

The invention relates to a dental implant, comprising an implant part, an abutment part and a central positioning bolt, which is characterized in that a peripheral cylindrical spiral body of the implant part is divided into three sections of an implant shoulder part, an implant main body part and an implant cone part, a self-tapping slot is formed on the cone part, an inner hole which can be inserted in the abutment part to form the inner intubation sleeve type connection is formed therein; the inner hole is divided into the upper section of a conical part, the middle section of an implant inner hole deep part and the lower section of an implant inner thread with the diameter less than that of the middle section; the abutment part is a rotary body which is sequentially reverse conical, positive curved, positive conical and cylindrical from top to bottom at the periphery, the abutment part can be a solid body and can also be the rotating body with a through hole which can be equipped with the central positioning bolt at the center, and the periphery thereof is a circular table which is sequentially reverse conical, positive curved, positive conical and cylindrical. The dental implant of the invention has rapid implantation, great strength, tight positioning and early retention, which can prevent the rotation, transfer the scattered bite force and scatter the stress function of the central bolt.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and relates to a dental implant with fast implantation, high strength, early fixation and anti-rotation. Background technique [0002] Since the early 1980s, oral implantology has opened up a new field for the dental community, and implant restoration has become a rapidly developing and reliable means of restoration, and has gained an important position in the field of stomatology. In terms of periodontal disease treatment, we have broken the single treatment concept of blindly retaining the affected teeth in the past treatment process, and increased the dental implant treatment plan. In the field of prosthodontics, dental implant treatment helps to achieve a successful esthetic and functional restoration. In the field of orthodontics, the problem of moving teeth is easily solved by using implants as anchorages. As the artificial tooth root of the denture retention device, dental implan...

AI Technical Summary

Problems solved by technology

Although the inserting part can be designed to be as long as 2.5mm to 30mm, but due to the limitation of design factors such as the diameter of the implant, the thinner implant cannot be designed as an inserting type due to the strength of the superstructure, and many inserting types The design of the insertion part is also too short, such as implant products such as Alpha-bio, BEGO, Biohorizons, Zimmer, and TBR, as well as designs disclosed in patent documents such as WO2006109176A1, US20060172257A1, US7249949B2, US7104797B2, WO2006088291A1, WO2006012273A1, US62837253B1, A81, WO2006012273A1, US62837253B1, etc.

②In terms of anti-rotation design, most of the anti-rotation designs in the prior art are exposed on the top of the implant shoulder, such as NobelReplace and other implants, as well as WO2006012236A3, WO2005067811A1, DE20022420U1, US7014464B2, WO2006109176US, US7309231B2, US500601999151A , US005823776A and other patent documents, its defect is that if it is screwed into a one-piece solid abutment, after it is in place, there will be gaps between the upper mouth of the implant shoulder and the abutment that are not tightly connected, leaving room for germs and viruses. living space

③现有技术的设计中,植体颈部大多是光滑面,如US20070111164A1、DE20022420U1、US7309231B2、US20060199151A1、US20060172257A1、WO2005067811A1、WO2006012273A1、US20060172257A1、US7014464B2、US7108510B2、US6659770B2、US7249949B2、US6733291B1等专利文献所披露的的 The design, flawed, is detrimental to the early retention and osseointegration of the cortical bone
