Description
Technical field
This utility model relates to Dental implantion recovery technique, particularly relates to one kind and plants dental case.
Background technology
At present, conventional dental case of planting mostly is made up of the multi-part such as implantation body and base station.Between its parts, adopt is threaded or the mode such as grafting realizes stable connection more.Due to the effect of alternating force often will be subject in application, between its syndeton, very easily there is situations such as loosening, rotate and come off, very easily cause planting tooth failure, and then bring secondary injury to patient.And the setting of cushioning effect can be played owing to lacking between its link again, cause in its use procedure that stressing conditions is poor, the life-span is shorter.Meanwhile, again because structural design limit, existing biocompatibility of planting between dental case and body bone tissue is poor, implants the latter two and easily produces repulsion, and then causes shorten further its service life.In addition, existing design plant dental case after the implantation, its bottom tip unbalance stress, had a strong impact on postoperative comfort.
Utility model content
The purpose of this utility model is to provide to plant a dental case, and stable connection between this building block of planting dental case, biocompatibility are better, and in use stressing conditions is good.
The purpose of this utility model is achieved through the following technical solutions:
Plant a dental case, it is characterized in that: it is made up of implantation body, spring, base station and ring-type porous tantalum product; The inside, middle and upper part of described implantation body is provided with endoporus, and the diameter in the middle part of endoporus is greater than the diameter of endoporus top and the bottom; The body appearance of described implantation body is provided with annular recess, and is attached with one deck ring-type porous tantalum product in annular recess; The afterbody of described implantation body is set to smooth hemisphere face; Described base station bottom is provided with connecting rod; The inside of described connecting rod is provided with in order to place the draw-in groove installing described spring, and the bottom of described connecting rod is set to the leg with barb; Described connecting rod is plugged in described endoporus, and the barb in connecting rod lower leg is engaged in the middle part of endoporus, and catches on upper surface in the middle part of endoporus; Described spring is engaged in described draw-in groove and described endoporus simultaneously.
For increasing the stability of connection further and being beneficial to uniform stressed, the above-mentioned leg with barb is symmetrical multiple.
Above-mentioned ring-type porous tantalum product, its porosity is 50% ~ 60%.Through adopting the ring-type porous tantalum product of this porosity, be attached in the annular recess of implantation body's body appearance, define composite structure, while meeting mechanical property requirements, osseous tissue also can be 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 ring-type porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
For ease of installing artificial tooth in the top of base station correspondence, the middle part of above-mentioned base station is set to column, and top is set to Rotary-table.
This utility model has following beneficial effect:
This utility model provides one kind and plants dental case, it is by when mounted, base station lower coupling pole will be set to the leg with barb, insert the endoporus center of implantation body, be engaged in the middle part of endoporus via the barb on leg, and catch on upper surface in the middle part of endoporus, and then achieve combining closely of implantation body and base station; And between base station and implantation body mounting spring, both can play and support the effect of base station, can play cushioning effect when base station is stressed again, in use stressing conditions is good, the life-span is long to make tooth implant.In addition, porous tantalum product is attached with in its structure, both the overall excellent mechanical property requirements of structure had been met, but also introduce loose structure in the structure, achieve growing into of body bone tissue 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 as the restriction of restriction this utility model protection domain.
As shown in Figure of description 1-4, plant dental case for one kind, it is made up of implantation body 1, spring 2, base station 3 and ring-type porous tantalum product 9; The inside, middle and upper part of its implantation body 1 is provided with endoporus 4, and the diameter in the middle part of endoporus 4 is greater than the diameter of endoporus 4 top and the bottom; The body appearance of this implantation body 1 is provided with annular recess 10, and is attached with the ring-type porous tantalum product 9 that a layer porosity is 55% ~ 58% in annular recess 10; The afterbody of this implantation body 1 is set to smooth hemisphere face 11; Its base station 3 bottom is provided with connecting rod 5, and the inside of this connecting rod 5 is provided with the draw-in groove 6 placing mounting spring 2; The bottom of this connecting rod 5 is set to four symmetrical legs 8 with barb 7; Its connecting rod 5 is directly plugged in endoporus 4, and the barb 7 in connecting rod 5 lower leg 8 is engaged in the middle part of endoporus 4, and catches on upper surface in the middle part of endoporus 4; Its spring 2 is engaged in draw-in groove 6 and endoporus 4 simultaneously; The middle part of its base station 3 is set to column, and top is set to the Rotary-table that upper bottom surface area is less than bottom surface area; By the top Corresponding matching at base station 3, artificial tooth is installed, namely achieves the implantation of artificial tooth.
When application is installed, base station 3 lower coupling pole 5 will be set to the leg 8 with barb 7, insert endoporus 4 center of implantation body 1, be engaged in the space in the middle part of endoporus 4 via the barb 7 on leg 8, and simultaneously barb 7 catches on upper surface in the middle part of endoporus 4, and then achieve combining closely of implantation body 1 and base station 3.Through the growth of alveolar bone after implantation, namely its osseous tissue can grow into this ring-type porous tantalum product 9 inside configuration and structure of growing in being formed, considerably increase the stability after the biocompatibility of its structure entirety, implantation and anti-rotation performance, extend service life and improve implantation comfort level.In addition, its implantation body 1 afterbody is designed to smooth hemisphere face 11, increases and implants bottom lifting surface area, be beneficial to the uniform stressed of infrastructure, and improve postoperative comfort.
