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 dental implant 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 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.
Visible, existing composition of planting dental structure usually includes the structures such as implant, maintenance platform and corona, but the syndeton of its implant and maintenance interstation is comparatively complicated various, plants tooth process operation comparatively loaded down with trivial details.Dental Implant can not wait sclerotin weakness implant is most advanced and sophisticated after implantation, then add as bone grafting material, biotic factor etc. other to increase the material of planting tooth steadiness, often sclerotin is plentiful not, easily causes and plants tooth failure.Meanwhile, it is planted in dental structure design and also has certain defect, 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, when 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 after device corona, through life-time service or improper use, maintenance platform also can rupture sometimes, corona is come off and can not re-use.Now, residual implant after fracture need be extracted, to re-assembly, so also equal to plant tooth failure.
Utility model content
The purpose of this utility model is to provide a kind of single-piece dental implant structure, this single-piece dental implant structure can be avoided the interference of alternating force preferably, simple in structure, be convenient to manufacture, the tip that also other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor can be introduced to Dental Implant, and there is certain repair function, and simple in structure, have good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of single-piece dental implant structure, 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 and described maintenance platform adopt porous tantalum product one-body molded, and its porosity is 60% ~ 70%; Described implant is made up of cervical region, middle part and afterbody; 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; The inside of this single-piece dental implant structure, is also provided with from the upper surface of described maintenance platform vertically downward and the through hole communicating with described groove.
Through adopting implant and the maintenance platform of porous tantalum product of above-mentioned porosity, can meet the mechanical property requirements of this single-piece dental implant 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 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 adopts porous tantalum product one-body molded implant and maintenance platform, and the connection of having saved the two is 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, through hole this single-piece dental implant inside configuration setting, that communicate with groove, also can, in the time that fracture occurs maintenance platform, utilize the space in its through hole to imbed a stud, the maintenance platform of its fracture is repaired, again maintenance platform and implant are connected as one;
5, by be provided with the through hole communicating with the groove of the inside, lower end of implant in its structure, realize the sclerotin weakness such as implant bottom have been introduced, have been evenly distributed on to other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor, and increased the stability that this structure is connected with sclerotin, make implantation body and bony fusion faster, better;
6, 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.
