Description
Technical field
This utility model relates to oral cavity canine implant, relates in particular to a kind of inserted type Dental Implant.
Background technology
At present, oral cavity canine implant technology, because it has unique technical advantage, and has obtained good development, applies more and more extensively, becomes highly effective medical skill means.
Yet in clinical practice, this technology still exists many technical problems to need to solve, for example, existing Dental Implant mostly is a plurality of independently assembling parts and forms, identical components diversity in each structural design is larger, does not have general applicability, plants tooth process operation comparatively loaded down with trivial details; Its mechanical property and biocompatibility are poor, there will be repulsion, and affect its service life after long-time use with tissue; After implanting, is connected defective tightness, firm with body bone tissue, easily becomes flexible and sinking or come off; It is firm not between all parts in its structure, to connect; Be subject to alternating force effect when mounted or in using, easily occur loosening or come off etc.
Utility model content
The purpose of this utility model is to provide a kind of inserted type Dental Implant, and this inserted type Dental Implant is simple in structure, simple installation, connection are reliable, has resilience function and can resist alternating force effect, and have good biocompatibility concurrently.
The purpose of this utility model is achieved in that
An inserted type Dental Implant, is characterized in that: it comprises foundation pile, base station, artificial tooth and extension spring; Described base station is directly fixed on described foundation pile upper end, and base station side is provided with groove, in this groove, has spring, and there is slide block in spring outside; In described artificial tooth, correspondence is provided with the caulking groove that slide block is installed; Described foundation pile is comprised of cervical region, middle part and afterbody, and this foundation pile employing porous tantalum product, and its porosity is 60% ~ 70%; This foundation pile middle part outer surface is provided with the regular screw threads of the outer surface that protrudes from its cervical region and afterbody; In this foundation pile bottom, be provided with groove; This recess sidewall is provided with ridged annular projection; Described extension spring is located in this groove, and fixes by the ridged annular projection on its sidewall.
Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.This slide block also can be set to the object that other sides such as right angle trigonometry body are inclined-plane, or the object of other shapes.
Above-mentioned base station is cuboid, and with artificial tooth corresponding matching, further to increase anti-axial-rotation.
Further, above-mentioned foundation pile is cylindrical shape, and the diameter of its cervical region and afterbody is consistent.By this structure, arrange, and in conjunction with the regular screw threads of the outer surface that protrudes from its cervical region and afterbody of its foundation pile middle part outer surface setting, it has realized the contact area having increased between this structure and osseous tissue, fits tightr, and has and the effect such as further prevent from, come off.
Further, above-mentioned base station is specifically realized and being fixedly connected with of above-mentioned foundation pile by welding or boning.Its connected mode is simple, and has realized the two is connected to an integral body, i.e. integral type.
In this utility model, base station and foundation pile are integral type, have simplified connection, be convenient to produce, and whole good stress performance; Its foundation pile overall structure adopts the porous tantalum product of above-mentioned porosity, met its structural mechanical property requirement in application, and also make osseous tissue grow into and the structure of growing in having formed, thereby organically combine as a whole with body bone tissue, when greatly having improved biocompatibility, also well meet its mechanical property, improved service life and implanted comfort level, increased stability and anti-verticity after artificial prosthesis is implanted; By structures such as extension springs, realized and continued its overall structure to apply active force, in use, if become flexible because of external force, extension spring makes it again keep close contact by elastic force, and then has guaranteed fixed effect.In addition, the regular screw threads of the outer surface that protrudes from its cervical region and afterbody of its foundation pile middle part outer surface setting, realized the contact area increasing between this structure and osseous tissue, fit tightr, and until body bone tissue growth and after it is closely connected, can not only effectively prevent the sinking of its structural entity, the osseous tissue that can also connect by its upper end growth fixedly prevents from coming off.

The specific embodiment
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figures 1 to 3: a kind of inserted type Dental Implant, it includes foundation pile 1, base station 2, artificial tooth 3 and extension spring 8; Its base station 2 is directly fixed on foundation pile 1 upper end by laser weld, and base station 2 sides are provided with groove 4, in this groove 4, has spring 5, and there is slide block 6 in spring 5 outsides, and this slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area; The interior correspondence of artificial tooth 3 is provided with the caulking groove 7 that slide block 6 is installed; Its foundation pile 1 is comprised of cervical region, middle part and afterbody, and this foundation pile 1 employing porous tantalum product, and its porosity is 60% ~ 70%, and this porous tantalum product specifically can adopt method preparation described in patent 201110296515.7; This foundation pile 1 middle part outer surface is also provided with the regular screw threads 11 of the outer surface that protrudes from its cervical region and afterbody; In this foundation pile 1 bottom, be also provided with groove 9, these groove 9 sidewalls are provided with ridged annular projection 10; Its extension spring 8 is located in this groove 9, and fixing by the ridged annular projection 10 on its sidewall; This foundation pile 1 is cylindrical shape, and the diameter of its cervical region and afterbody is consistent; Its base station 2 is cuboid, and with artificial tooth 3 corresponding matching, and then realized the implantation of artificial tooth.
In clinical practice, after first extension spring 8 one end being fixed on the alveolar bone of bottom, again groove 9 correspondences in foundation pile 1 bottom are contained on the other end of extension spring 8, firmly rotation can be fixed by the ridged annular projection 10 on groove 9 sidewalls after depressing, and then by the effect of pulling force, the alveolar bone of having realized itself and bottom is close contact all the time, also realized and continue its overall structure to apply active force simultaneously, in use, if become flexible because of external force, extension spring 8 makes it again keep close contact by elastic force, and then guaranteed fixed effect.In addition, by base station 2 heads are processed with to groove 4, and configuration can, at the slide block 6 of groove 4 interior slips, along with artificial tooth 3 is toward lower slider, promote slide block 6 to the interior movement of groove 4, after artificial tooth 3 moves into place, slide block 6 embeds in caulking groove 7, now by the effect of spring 5, makes slide block 6 can keep chimeric closely with caulking groove 7, thereby play well anti-axially movable effect, and anti-loosening and effect that come off.
