Abstract
The utility model relates to a dental implant structure. The dental implant structure consists of an implant (1), a fixing table (2) and a tension spring (4), wherein the fixing table (2) is arranged at the upper end of the implant (1), and the implant (1) and the fixing table (2) are formed through carrying out integrated molding on porous tantalum parts and have the porosity of 60-70%; the lower end part (6) of the implant (1) is bullet-shaped, and a groove (3) is formed inside the lower end part (6); a ridge-shaped annular bulge (5) is arranged on the internal sidewall of the groove (3); the tension spring (4) is arranged in the groove (3) and is fixed through the ridge-shaped annular bulge (5) on the sidewall of the groove (3). The dental implant structure is simple and has good biocompatibility, the tight and stable connection with the alveolar bone can be realized, and the interference resulting from alternating force can be better avoided.
Description
Technical field
This utility model relates to Medical oral cavity manual tooth planting's medical apparatus and instruments, relates in particular to one kind 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 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 also there is certain defect in of the prior art planting in dental structure design, cause its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.Meanwhile, existing composition of planting dental structure includes implant, maintenance platform and corona; 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.
Utility model content
The purpose of this utility model is to provide one kind to plant dental structure, and it is simple in structure that this plants dental structure, can realize with closely firm being connected of alveolar bone, can also avoid preferably the interference of alternating force, have good biocompatibility concurrently.
The purpose of this utility model is achieved in that
Plant a dental structure, 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, and described implant and described maintenance platform adopt porous tantalum product one-body molded, and its porosity is 60% ~ 70%; The bottom of this implant 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, can meet this 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, the body of above-mentioned implant is cylinder.Be preferably cylinder, and this cylindrical diameter is identical with the maximum gauge of the bottom of implant.Its structural entity of the implant of this structure setting is similar to bullet shaped, the bottom smooth surface that it is bullet-headed, is beneficial to implantation process, and and can realize this structural entity and firmly hammer in body bone tissue, firmly be connected thereby realized with alveolar bone, and increased the effects such as stable connection.
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,, by one-body molded to implant and the employing of maintenance platform, 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 ensured fixed effect;
3, its overall structure itself 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 bottom 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, and be firmly connected with alveolar bone thereby realized, further increase the effects such as stable connection.
Brief description of the drawings

Fig. 2 is the structural representation of planting dental structure integrated connection 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.
Embodiment 1
As shown in Fig. 1～2: plant dental structure for one kind, it is made up of implant 1, maintenance platform 2 and extension spring 4; Its maintenance platform 2 is arranged at the upper end of implant 1, and implant 1 and maintenance platform 2 adopt porous tantalum product one-body molded, and its porosity is 60% ~ 70%; The bottom 6 of this implant 1 is set to bullet-headed, and its inside 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 body 7 of its implant 1 is cylinder, and this cylindrical diameter is identical with the maximum gauge of the bottom 6 of implant 1; Its maintenance platform 2 is Rotary-table, with Corresponding matching, corona is installed, 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 by with on the corresponding other end that is contained in extension spring 4 of groove 3 on the integrated implant 1 of maintenance platform 2, 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 ensure fixed effect.
