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 single-piece and plants 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 existing clinical practice, plant tooth body and in use can be subject to for a long time the effect of 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 existing composition of planting dental structure includes plants tooth body, retained abutment and corona, and syndeton is therebetween comparatively complicated various, plant tooth process operation comparatively loaded down with trivial details.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 single-piece to plant dental structure, and this single-piece is planted dental structure and can be closely connected with alveolar bone in real time, can avoid preferably the interference of alternating force, simple in structure, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of single-piece is planted dental structure, it 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, 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 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 the implant of porous tantalum product of above-mentioned porosity, can meet this single-piece and plant the mechanical property requirements of 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, above-mentioned implant is cylinder, and the cervical region of this implant and the diameter at middle part 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, above-mentioned maintenance platform is Rotary-table, and realizes and being fixedly connected with of above-mentioned implant through bonding or welding.The maintenance platform of this Rotary-table shape, can install corona in order to Corresponding matching, and then has realized 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, 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;
3, 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;
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.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram that single-piece described in this utility model embodiment 1 is planted dental structure.
Fig. 2 is the structural representation that described in Fig. 1, single-piece is planted dental structure integrated connection.
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 single-piece is planted dental structure, it is made up of implant 1, maintenance platform 2 and extension spring 4; Its maintenance platform 2 adopts medical titanium alloy to make, and is fixedly installed on the upper end of implant 1; Implant 1 cylinder for being formed by cervical region 6, middle part 7 and afterbody 8, and this implant 1 adopts porous tantalum product, and its porosity is 60% ~ 70%; 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; Its implant 1 is cylinder, and the cervical region 6 of this 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; Its maintenance platform 2 is Rotary-table, and realizes and being fixedly connected with of implant 1 through laser weld; The maintenance platform 2 of this Rotary-table shape, installs corona with Corresponding matching, 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.
