The integrated tooth implantation component has a simple structure, can be used for well avoiding interference of alternating force, and has excellent mechanical performance and biocompatibility.
Description
Technical field
This utility model relates to Medical oral cavity manual tooth planting's medical apparatus and instruments, relates in particular to a kind of integral type and plants implant component.
Background technology
Oral cavity implanting tooth is to repair at present a mouthful best method for inner teeth gear disappearance.Dental implant surgical of the prior art, normally plants tooth body by one and directly imbeds in advance dental bed, after above planting tooth body, install a retained abutment separation and that expose to dental bed surface, a corona is finally installed in this retained abutment again again, to realize the implantation of artificial tooth.
In clinical practice, the effect of planting tooth body and in use can be subject to for a long time alternating force of the oral cavity implanting tooth of existing design, particularly work as Dental Implant when mounted, if move past manyly to words lateral deviation, easily occur in a short time loosening, and unreasonable owing to planting the design of tooth body structure, 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.And the existing implant component of planting often includes and plants tooth body, retained abutment and corona, it is comparatively complicated various that it plants syndeton between tooth body and retained abutment, plants tooth process operation comparatively loaded down with trivial details.In addition, single-piece of the prior art is planted dental structure and is had in design certain defect, causes its mechanical property and biocompatibility poor, there will be repulsion, and affect the problems such as its service life after long-time use with tissue.
Utility model content
The purpose of this utility model is to provide a kind of integral type to plant implant component, and it is simple in structure that this integral type is planted implant component, can avoid preferably the interference of alternating force, has good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of integral type is planted implant component, it is characterized in that: it is made up of implant, maintenance platform and extension spring; Described maintenance platform is arranged at the upper end of described implant; Described implant is made up of body and afterbody; Described implant and described maintenance platform adopt porous tantalum one-body molded, and its porosity is 60% ~ 70%; The body outer surface of this implant is provided with regular screw threads, and the inside of its afterbody is provided with groove; On sidewall in this groove, be provided with ridged annular projection; Described extension spring is arranged in this groove, and fixes by the ridged annular projection on its sidewall.
Through adopting implant and the maintenance platform of porous tantalum product of above-mentioned porosity, in structure, be set to an entirety, not only meet this integral type and planted the mechanical property requirements of implant component in application, and through adopting porous tantalum structure, can also make bone grow into and the structure of growing in forming, thereby organically combine as a whole with body bone tissue, in greatly having improved biocompatibility, also well meet its mechanical property, improve service life and implanted comfort level, having increased stability and anti-verticity after artificial prosthesis is implanted.This porous tantalum product can adopt the preparations such as foam dipping method, die pressing.
Further, above-mentioned implant is cylinder, and the diameter of this implant afterbody is short compared with the diameter of body.The implant of this structure setting has been realized with alveolar bone and being firmly connected, and has the effects such as the sinking of further preventing.
Further, above-mentioned maintenance platform is Rotary-table or cylinder.The maintenance platform of this Rotary-table shape or cylindrical shape, can install corona in order to Corresponding matching, and then has realized the implantation of artificial tooth.
The utlity model has following beneficial effect:
1, this utility model is simple in structure, and it has saved the annexation of the two by one-body molded to implant and the employing of maintenance platform, be convenient to produce, and overall good stress performance;
2, adopt extension spring one end is fixed on the alveolar bone of bottom, the other end is fixed in the groove of inside, implant lower end, and realize the alveolar bone close contact all the time of this structure 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 makes it again keep close contact by elastic force, and then has guaranteed fixed effect;
3, in its structure, implant and maintenance platform adopt porous tantalum one-body molded, well meet its mechanical property, also greatly increase its biocompatibility simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted;
4, the outer surface of its implant body is also provided with regular screw threads, has further strengthened with the firm of alveolar bone and has been connected.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram that integral type described in this utility model embodiment 1 is planted implant component.
Fig. 2 is the Integral connection structure schematic diagram that integral type described in Fig. 1 is planted implant component.
The specific embodiment
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
As shown in Fig. 1～2: a kind of integral type is planted implant component, it is made up of implant 1, maintenance platform 2 and extension spring 4; The maintenance platform 2 of its Rotary-table shape is arranged at the upper end of implant 1; The cylinder of implant 1 for being formed by body 6 and afterbody 7, and the diameter of the afterbody 7 of this implant 1 is short compared with the diameter of body 6; Wherein, implant 1 and maintenance platform 2 adopt porous tantalum one-body molded, and its porosity is 60% ~ 70%; The outer surface of the body 6 of this implant 1 is provided with regular screw threads 8, and the inside of afterbody 7 is provided with groove 3; On sidewall in this groove 3, be provided with ridged annular projection 5; Extension spring 4 is arranged in this groove 3, and fixing by the ridged annular projection 5 on its sidewall; On the maintenance platform 2 of this Rotary-table shape, Corresponding matching is installed corona, and then has realized the implantation of artificial tooth.
In clinical practice, after first extension spring 4 one end being fixed on the alveolar bone of bottom, again 3 correspondences of the groove on implant 1 are sleeved on the other end of extension spring 4, can be by the ridged annular projection 5 on groove 3 sidewalls by fixing this extension spring 4 after firmly depressing, and then by the pulling force of extension spring 4, 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 makes it again keep close contact by elastic force, and then guarantee fixed effect.
