Description
Technical field
This utility model relates to artificial tooth implantation technology, particularly relates to a kind of oral tooth implantation root.
Background technology
At present, what adopt in tooth implant structure plants root of the tooth, owing to being often subject to the effect of alternating force in implantation process and the application after implanting, but its structure is mostly made up of multi-part, and between its parts, lacked the setting of cushioning effect, cause that its stressing conditions is poor, easily loosen, rotate and come off between structure, very easily cause plant dental structure service life shorter, plant tooth failure, and then bring the situations such as secondary injury to patient.In addition, the connective stability between existing tooth implant structure and body bone tissue and biocompatibility, also need to be improved raising, plants tooth success rate to increase it further.
Utility model content
The purpose of this utility model is to provide a kind of oral tooth implantation root, and between this oral tooth implantation root part, stable connection, stressing conditions better, and have good biocompatibility concurrently.
The purpose of this utility model is achieved through the following technical solutions:
A kind of oral tooth implantation root, is characterized in that: it is made up of implantation body, cushion pad and base station; Described implantation body inside is provided with endoporus, and the diameter of endoporus bottom is greater than the diameter on endoporus top; The bottom of described base station is a connecting rod, and the bottom of connecting rod is set to the leg with barb; Described connecting rod is plugged in described endoporus, and the barb on leg is engaged in endoporus bottom, and catches on the upper surface of endoporus bottom; Be provided with a spacer between the upper surface of described connecting rod and the upper surface of described implantation body, in this spacer, be provided with described cushion pad; The bottom of described implantation body is porous tantalum product; The upper side of described base station is provided with an anti-rotational right angle tangent plane.
For making this oral tooth implantation root and osseous tissue mutually chimeric tight further, increase its connective stability, the upper outer of above-mentioned implantation body is provided with rectangular thread or trapezoidal thread.As preferred further, the thread form angle of above-mentioned trapezoidal thread is greater than 90 °, is less than or equal to 135 °.By arranging trapezoidal thread or rectangular thread on the upper outer of implantation body, while its structural mechanics intensity of guarantee, increase the contact area of implantation body's upper outer and dental bed inner bone tissues, enhance the adhesive force that it is mutual, and grow in thread gaps by osseous tissue, and make this artificial structure and osseous tissue mutually chimeric tight, further increase its connective stability.
For increasing the stability of connection further and being beneficial to uniform stressed, the above-mentioned leg with barb is symmetrical multiple.
Above-mentioned porous tantalum product, its porosity is 50% ~ 60%.Through adopting the bottom of porous tantalum product as implantation body of this porosity, while making it meet excellent mechanical property requirements, osseous tissue is also made to grow into this loose structure structure of growing in inwardly filling and then being formed, thus to achieve that artificial prosthesis and osseous tissue organically combine be one overall, substantially increase its biocompatibility, extend service life and improve implantation comfort level, adding the stability after artificial prosthesis implantation and anti-rotation performance.This porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
For ease of implant procedure, improve plantation success rate, the bottom of above-mentioned implantation body is set to pointed.
For simplifying syndeton, the upper and lower of above-mentioned implantation body, be connected to one especially by welding or bonding.Its connected mode is simple, and to achieve anatomical connectivity be one overall.
This utility model has following beneficial effect:
This utility model provides a kind of oral tooth implantation root, it is by arranging cushion pad in the spacer between base station and implantation body, both served and supported the effect of base station, served cushioning effect when base station is stressed again, made its structure in use good, long service life of stressing conditions; And be stuck in via the barb on leg and catch in endoporus and cannot extract, and then achieve combining closely of himself structure.In addition, porous tantalum product is introduced in its structure, both excellent mechanical property requirements had been met, achieve growing into of body bone tissue again and structure of growing in being formed, considerably increase the stability after the biocompatibility of structure entirety, implantation and anti-rotation performance, extend service life and improve implantation comfort level.

Detailed description of the invention
Following examples are only and further illustrate the adoptable detailed description of the invention of this utility model, can not be interpreted as the restriction of this utility model protection domain.
As shown in Figure of description 1-5, a kind of oral tooth implantation root, it is made up of implantation body 1, cushion pad 2 and base station 3; Its implantation body 1 inside is provided with endoporus 4, and the diameter of endoporus 4 bottom is greater than the diameter on endoporus 4 top; The upper side of its base station 3 is provided with one in order to the anti-rotational right angle tangent plane 9 of Matching installation corona; The bottom of its base station 3 is a connecting rod 5, and the bottom of connecting rod 5 be set to four symmetrical and with the leg 7 of barb 6; Its connecting rod 5 is directly plugged in endoporus 4, and the barb 6 on leg 7 is engaged in endoporus 4 bottom, and catches on the upper surface of endoporus 4 bottom; Be provided with a spacer 8 between the upper surface of this connecting rod 5 and the upper surface of implantation body 1, in this spacer 8, be provided with cushion pad 2; The top of its implantation body 1 adopts conventional medical titanium alloy product, and upper outer is provided with the trapezoidal thread 11 that thread form angle equals 100 °; This implantation body 1 bottom is set to the porous tantalum product 10 that porosity is 50% ~ 52%, and is set to pointed bottom it; The upper and lower of this implantation body 1, is connected to one especially by laser weld.
When application is installed, by the leg 7 with barb 6 through spacer 8, insert in the endoporus 4 in implantation body 1 afterwards again, be stuck in endoporus 4 via the barb 6 on leg 7, and catch on the upper surface of endoporus 4 bottom and cannot extract, namely achieve combining closely of implantation body 1 and base station 3, and both it between cushion pad 8, both served and supported the effect of base station 3, served cushioning effect when base station 3 is stressed again, made its structure in use good, long service life of stressing conditions.
