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 directly imbeds dental bed in advance by an implant, after above implant, install a maintenance platform separation and that expose to dental bed surface, finally on this maintenance platform, a corona is installed again again, to realize the implantation of artificial tooth.
In clinical practice, the implant of the oral cavity implanting tooth of existing design in use can be subject to the effect of alternating force for a long time, particularly work as Dental Implant 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.
The existing implant component of planting often includes implant, maintenance platform and corona, and the syndeton of its implant and maintenance interstation is comparatively complicated various, plants tooth process operation comparatively loaded down with trivial details; And implant is the standing cylindricality of counting generally, and with body bone tissue between while being connected steadiness poor, be also not easy to implantation process operation.In addition, there is certain defect in the dental structure of planting of the prior art, causes its mechanical property and biocompatibility poor in design, 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 its afterbody is set to bullet-headed, and its inside 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, the body of above-mentioned implant is cylinder, and this cylindrical diameter is identical with the maximum gauge of implant afterbody.The implant structural entity of this structure setting is similar to bullet shaped, firmly hammers in body bone tissue and can realize this structural entity, is firmly connected, and has increased the effects such as stable connection thereby realized with alveolar bone.Its bullet-headed tail surface is smooth, is also beneficial to implantation process.
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 ensured 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 afterbody of its implant is set to bullet-headed, the effect of this structure setting is similar to the nail tip portion of screw, and can make this implant firmly hammer in body bone tissue, firmly be connected thereby realized with alveolar bone, the effects such as stable connection are further increased, and its smooth surface, is also beneficial to implantation process;
5, 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.
