Description
Technical field
This utility model relates to oral cavity manual tooth planting, relates in particular to spindle Dental Implant.
Background technology
At present, oral cavity manual tooth planting, because having the advantages such as reliability is high, persistency is strong, has obtained good development in recent years, applies more and more extensive.But along with the popularization of this technology, it also manifests many technical disadvantages gradually, concrete as: existing canine implant is mostly designed to multiple individual components and assembles, it exists member more, and the identical components diversity in each design is larger, do not there is general applicability, plant the shortcomings such as tooth process operation is comparatively loaded down with trivial details.Simultaneously existing canine implant is connected defective tightness, firm after implantation with body bone tissue, and easily loosening and sinking or come off, very easily brings secondary injury to patient.In clinical practice, it also can be subject to the effect of alternating force for a long time, particularly when mounted, if move past to words lateral deviation many, easily occur in a short time loosening, and because its structural design is unreasonable, cause this becoming flexible can not again tighten at present, can only again plant, thereby increase the operations such as plantation again, cause significant wastage.
Utility model content
The purpose of this utility model is to provide a spindle Dental Implant, and this spindle Dental Implant is reasonable in design, simple in structure, simple installation, has resilience function and can avoid preferably the interference of alternating force, has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
Spindle 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 in base station, is provided with through hole, in this through hole, has spring, and both ends of the spring is arranged with slide block; In described artificial tooth, correspondence is provided with the caulking groove that slide block is installed; Described foundation pile adopts porous tantalum product, and its porosity is 60% ~ 70%, and this foundation pile is the spindle structure that top and the bottom are thin, middle part is thick; 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 top and the bottom and middle part are cylindrical respectively, and the diameter of its top and the bottom is consistent; The diameter at its middle part is long compared with the diameter of top and the bottom.The foundation pile of this structure setting has and the effect such as further prevents 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 entirety, i.e. integral type.
In this utility model, base station is directly fixed on to foundation pile upper end by welding or boning, has realized its two integral type and connected, simplified its structural design, and be connected to rear its good stress performance of an entirety, be convenient to produce and plant tooth process operation; Simultaneously, its foundation pile adopts the porous tantalum product of above-mentioned porosity, well meet its structural mechanical property in application, also make osseous tissue grow into and the structure of growing in having formed, thereby organically combine as a whole with body bone tissue, greatly increase its biocompatibility, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted.In addition, the foundation pile of its spindle structure after it is closely connected, can not only effectively prevent the sinking of its structural entity until body bone tissue growth, and the osseous tissue that can also connect by its upper end growth fixedly prevents from coming off.

Detailed description of the invention
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: spindle 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 in base station 2, be provided with rectangular through-hole 4, in this rectangular through-hole 4, have a spring 5, spring 5 two ends are respectively provided with respectively a slide block 6, and this slide block 6 is the right-angled trapezium body that upper surface area is less than lower surface area; The interior correspondence of its artificial tooth 3 is provided with the caulking groove 7 that slide block 6 is installed; Its foundation pile 1 adopts porous tantalum product, its porosity is 60% ~ 70%, this porous tantalum product specifically can adopt method preparation described in patent 201110296515.7, and this foundation pile 1 is the spindle structure that top and the bottom are thin, middle part is thick, be specially its foundation pile 1 upper and lower part and middle part respectively for cylindrical, the diameter of its top and the bottom is consistent, and the diameter at its middle part is long compared with the diameter of top and the bottom; 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; Its base station 2 is cuboid, adopts medical titanium alloy to make, 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, realize the alveolar bone close contact all the time of itself and bottom, 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 ensure fixed effect.In addition, the foundation pile 1 of its spindle structure is until body bone tissue growth and after it is closely connected, can not only effectively prevent the sinking of its structural entity, can also prevent that it from coming off by the effect that the osseous tissue that connects fixes to resist power upwards of growing of its upper end.
