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 implant dental structure.
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 planting tooth body, 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 existing clinical practice, implant 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.And existing composition of planting dental structure includes implant, maintenance platform and corona, syndeton is therebetween 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.In addition, there is certain defect in of the prior art planting in dental structure design, 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 implant dental structure, and this implant dental structure is simple in structure, and it is convenient to implant, and can avoid preferably the interference of alternating force, has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of implant dental structure, is characterized in that: it is made up of implant, maintenance platform and extension spring; Described maintenance platform is fixed on the upper end of described implant; Described implant is made up of cervical region, middle part and afterbody, and this implant employing porous tantalum product, and its porosity is 60% ~ 70%; The outer surface at this implant middle part is provided with regular screw threads, and 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 the implant of porous tantalum product of above-mentioned porosity, can meet the mechanical property requirements of this implant dental structure in application, and through adopting porous tantalum structure, can also make bone grow into and the structure of growing in forming, thereby as a whole with body bone tissue combination, 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 cervical region of above-mentioned implant is the consistent cylinder of diameter with middle part, 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, and realizes and being fixedly connected with of above-mentioned implant through bonding or welding.This Rotary-table shape or or the maintenance platform of cylindrical shape, can corona be installed in order to Corresponding matching, and then realize the implantation of artificial tooth.Its connected mode is simple, and has realized the two is connected to an entirety.
The utlity model has following beneficial effect:
1, this utility model is simple in structure, and it adopts implant and maintenance platform bonding or be welded into a single-piece, has simplified the connection of the two, be convenient to produce, and overall good stress performance;
2, 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 its smooth surface, also be beneficial to implantation process, and can make this implant firmly hammer in body bone tissue, firmly be connected thereby realized with alveolar bone, further increased the effects such as stable connection;
3, adopt extension spring one end is fixed on the alveolar bone of bottom, the other end is fixed on 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;
4, in its structure, implant adopts porous tantalum product, has well met its mechanical property, has also greatly increased its biocompatibility simultaneously, has improved service life and has implanted comfort level, has increased stability and anti-verticity after this artificial prosthesis is implanted;
5, the outer surface at its implant structure middle part is also provided with regular screw threads, has further strengthened with the firm of alveolar bone and has been connected.
