Problems solved by technology
Although the inserting part can be designed to be as long as 2.5 mm to 30 mm, 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 there are many inserting implants. The design of the insertion part is too short, such as Alpha-bio, BEGO, Biohorizons, Zimmer, TBR and other implant products, as well as the designs disclosed in patent documents such as WO2006109176A1, US20060172257A1, US7249949B2, US7104797B2, WO2006088291A1, WO2006012273A1, US62837253B1, A815, 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 Nobel Replace and other implants, as well as WO2006012236A3, WO2005067811A1, DE20022420U1, US7014464B2, WO2006109176A1, US7309231B2, US5, USDS, USDS, 48A The defects of the designs disclosed in US7108510B2, US005823776A and other patent documents are: if screwed into a one-piece solid abutment, the upper mouth of the implant shoulder and the abutment will not be tightly connected after being in place and there will be gaps, which will cause bacteria Viruses leave room to live
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

Embodiment Construction
[0037] Now in conjunction with accompanying drawing, the present invention will be further described
[0038] see figure 1 , Figure 10 : the pipe sleeve of the present invention puts and rotates the dental implant with a body implant part 10, an abutment part 20 and a central positioning bolt 34, and the outer circumference of the body implant part 10 is a cylindrical helical design, and the abutment part 20 is installed on the body implant part in the form of a pipe sleeve In the inner hole 9, the center positioning bolt 34 connects the two into one.
[0039] see figure 2 : The triangular double thread 16 of the main body part 12 of the implant can make the operation operation of screwing into the implant part more convenient and quick in addition to increasing the bonding force and the bonding area of the implant and the alveolar bone 6. When the implant is implanted, it has a guiding function to facilitate implantation, and the self-tapping groove 18 is used to cut t...

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, dental implantology has opened up a new field for the dental world. Implant restoration has become a rapidly developed and reliable restoration method, 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 implants have ...
