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 component of planting of oral cavity implanting tooth.
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.
Simultaneously, it is planted in dental structure design and also has certain defect, cause its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect its service life, and Dental Implant can not be at the most advanced and sophisticated sclerotin weakness that waits of implant after implantation, then adds as bone grafting material, biotic factor etc. that other plant the material of tooth steadiness with increase, often sclerotin is plentiful not, easily causes and plants tooth failure.
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, therefore need improvement badly.
Utility model content
The purpose of this utility model is to provide a kind of implant component of planting of oral cavity implanting tooth, this plants implant component and can be avoided preferably the interference of alternating force, 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, simple in structure, have good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
Oral cavity implanting tooth plant an implant component, 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 made up of body and afterbody; The body of described implant and afterbody adopt porous tantalum one-body molded, and its porosity is 60% ~ 70%; The body outer surface of this implant is provided with regular screw threads, and the inside of its 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 planting implant component of this oral cavity implanting tooth, is also provided with from the upper surface of described maintenance platform vertically downward and the through hole communicating with described groove.
Through adopting body and the afterbody of implant of porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of implant component 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 diameter of this implant afterbody is short compared with the diameter of body.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; And the body of this maintenance platform and above-mentioned implant employing welding or bonding connection are as a whole.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, and it adopts implant and maintenance platform welding or be bonded as one, and has simplified the annexation of the two, be convenient to produce, and overall good stress performance;
2, through hole its 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;
3, 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;
4, 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;
5, in its structure, the body of implant and afterbody adopt porous tantalum one-body molded, well meet its mechanical property, also greatly increase its biocompatibility simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted;
6, the outer surface of its implant body is also provided with regular screw threads, has further strengthened with the firm of alveolar bone and has been connected.
