Description
Technical field
This utility model relates to Medical oral cavity manual tooth planting, particularly relates to a Dnetal implant component.
Background technology
Manual tooth planting's operation of the prior art, normally plant tooth body by one and directly imbed dental bed in advance, after plant to install above tooth body one be separated and expose to the maintenance platform of dental surface, finally on this maintenance platform, a corona is installed again again, to realize the implantation of artificial tooth.
Such as, but in clinical practice, this technology still exists many technical problems to be needed to solve, existing Dental Implant mostly is multiple independently assembling parts and forms, identical components diversity in each structural design is comparatively large, does not have general applicability, and it is comparatively loaded down with trivial details to plant tooth process operation; Its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect its service life; Be connected defective tightness after implanting with body bone tissue, firmly, easily loosen and sink or come off; It is firm not to connect between all parts in its structure; Be subject to alternating force effect when mounted or in using, easily occur loosening or coming off etc.
Utility model content
The purpose of this utility model is to provide a Dnetal implant component, and this plants the interference that implant component can avoid alternating force preferably, and structure is simple, simple installation, connection are reliable, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
One Dnetal implant component, is characterized in that: it comprises plants tooth body, maintenance platform, artificial tooth and extension spring; Plant tooth body upper end described in described maintenance platform is directly fixed on, and be provided with through hole in maintenance platform, have spring in this through hole, both ends of the spring is arranged with slide block; In described artificial tooth, correspondence is provided with the caulking groove installing slide block; Described tooth body of planting is made up of body and afterbody, and its afterbody adopts porous tantalum product, and its porosity is 60% ~ 70%; This body outer surface of planting tooth body is provided with regular screw threads, is provided with groove in its afterbody; Sidewall in this groove is provided with ridged annular projection; Described extension spring is arranged in this groove, and is fixed by the ridged annular projection on its sidewall.
Above-mentioned slide block, is preferably the right-angled trapezium body that upper surface area is less than lower surface area.It is the object on inclined-plane that this slide block also can be set to other sides such as right angle trigonometry body, or the object of other shapes.
Above-mentioned maintenance platform is cuboid, and with artificial tooth corresponding matching, further to increase anti-axial-rotation.
Further, above-mentioned tooth body of planting is cylindrical shape, and the diameter of its afterbody is short compared with the diameter of body.The tooth body of planting of this vibrational power flow achieves and is firmly connected with alveolar bone, and has effects such as preventing sinking further.
Further, above-mentioned maintenance platform realizes planting being fixedly connected with of tooth body with above-mentioned particular by welding or bonding.Its connected mode is simple, and achieves that the two to be connected be one overall, i.e. integral type.
In this utility model, maintenance platform is by welding or boning, and achieves and plants tooth body and be fixed as one, simplifying connection, is convenient to produce, and overall good stress performance; Its afterbody of planting tooth body adopts the porous tantalum product of above-mentioned porosity, meet its structural mechanical property requirement in the application, and structure of growing in also making osseous tissue grow into and defining, thus organically combine as a whole with body bone tissue, while substantially increasing biocompatibility, also well meet its mechanical property, improve service life and implant comfort level, add the stability after artificial prosthesis implantation and anti-rotation performance; By arranging extension spring, achieving and being continuously applied active force to its overall structure, in use, if loosened because of external force, then extension spring makes it again keep close contact by elastic force, and then ensure that fixed effect.In addition, its body outer surface of planting tooth body is provided with regular screw threads, increases the contact area between this structure and osseous tissue, and laminating is more tight, effectively prevent the sinking of its structure entirety or comes 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: a Dnetal implant component, it comprises and plants tooth body 1, maintenance platform 2, artificial tooth 3 and extension spring 8; Its maintenance platform 2 is directly fixed on by laser weld plants tooth body 1 upper end, and is provided with through hole 4 in maintenance platform 2, and have spring 5 in this through hole 4, spring 5 two ends are respectively equipped with slide block 6, and this slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area; In its artificial tooth 3, correspondence is provided with the caulking groove 7 installing slide block 6; Plant tooth body 1 to be made up of body 13 and afterbody 12, and its afterbody 12 adopts porous tantalum product, its porosity is 60% ~ 70%, and this porous tantalum product specifically can adopt method preparation as described in patent 201110296515.7; This outer surface of planting tooth body 1 body 13 is provided with regular screw threads 11, is provided with groove 9 in its afterbody 12; Sidewall in this groove 9 is provided with ridged annular projection 10; Extension spring 8 is arranged in this groove 9, and is fixed by the ridged annular projection 10 on its sidewall; It plants tooth body 1 for cylindrical shape, and the diameter of its afterbody 12 is short compared with the diameter of body 13; Its maintenance platform 2 is cuboid, and with artificial tooth 3 corresponding matching, and then achieve the implantation of artificial tooth.
