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 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, existing effect of planting tooth body and in use can be subject to for a long time alternating force, 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 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.In addition, existing composition of planting dental structure has generally comprised plants tooth body, retained abutment and corona, and 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.
Utility model content
The purpose of this utility model is to provide a kind of implant dental structure, and this implant dental structure can be avoided the interference of alternating force preferably, simple in structure, 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 the cylinder being made up of cervical region, middle part and afterbody; The cervical region of described implant and afterbody adopt porous tantalum product, and its porosity is 60% ~ 70%; The outer surface at this implant middle part is provided with regular screw threads, and the inside of 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 cervical region and the afterbody of 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 and the diameter at middle part are consistent; The diameter of its afterbody is short compared with cervical region or middle part.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, the cervical region of above-mentioned implant and afterbody, realize and being fixedly connected with of the middle part of above-mentioned implant through bonding or welding respectively.Its connected mode is solid and reliable.
Further, above-mentioned maintenance platform is Rotary-table or cylinder, and is connected and fixed as a whole through welding or bonding and above-mentioned implant.Its connected mode is simple, and has realized the two is connected to an entirety.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, the cervical region of implant and afterbody are adopted porous tantalum product by it, well meet its mechanical property, also greatly increased its biocompatibility simultaneously, improve service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted;
2, it is also fixed on maintenance platform on implant, has further saved the connection of the two, be convenient to produce, and overall good stress performance;
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 ensured fixed effect;
4, 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.
Brief description of the drawings
Fig. 1 is the decomposition texture schematic diagram of implant dental structure described in this utility model embodiment 1.
Fig. 2 is the structural representation of the integrated connection of implant dental structure described in Fig. 1.
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.
As shown in Fig. 1～2: a kind of implant dental structure, 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 cervical region 6, middle part 7 and afterbody 8; Cervical region 6 and the afterbody 8 of this implant 1 adopt porous tantalum product, and its porosity is 60% ~ 70%, and realize and being fixedly connected with of the middle part 7 of implant 1 through laser weld respectively, and its middle part 7 employing medical titanium alloys are made; The outer surface at this implant 1 middle part 7 is provided with regular screw threads 9, and the inside of afterbody 8 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; The cervical region 6 of its implant 1 is consistent with the diameter at middle part 7; The diameter of its afterbody 8 is short compared with cervical region 6 or middle part 7; The maintenance platform 2 of this Rotary-table shape adopts medical titanium alloy to make, and realizes and is connected and fixed as a wholely with implant 1 through bonding, and maintenance platform 2 upper end Corresponding matchings install coronas, and then have realized the implantation of artificial tooth.
