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
The dental implant surgical of known current routine is by one, to plant tooth body to imbed in advance dental bed, after above this plants tooth body, install again the maintenance platform of a separation, finally by assemble again a corona on this maintenance platform, and realize the implantation of artificial tooth.But in clinical practice, it can be subject to the effect of alternating force for a long time, particularly when Dental Implant when mounted, if move past manyly to words lateral deviation, easily occur in a short time loosening, now it with body bone tissue between can not realize that close contact is connected, steadiness is poor, and because its structural design is unreasonable, cause this becoming flexible can not again to be tightened In the view of at present, can only again plant, thereby increased the operations such as plantation again, caused significant wastage.
In addition, in its structural design, also there is certain defect, cause its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect its service life; Simultaneously the tooth body of planting of existing structure also exists resistance larger when piercing between body bone tissue, pierces process and operation is very inconvenient, and the misery that patient suffers is larger.And existing planting in dental structure on its maintenance platform usually adopts the mode of directly installing that artificial tooth is installed, and its denture upper jaw power is difficult to adjusted distribution, and periodontal trauma easily occurs, and its canine implant load is larger, plant tooth success rate lower, service life is shorter.
Utility model content
The purpose of this utility model is to provide a kind of implant dental structure, and this implant dental structure steadiness is better, can avoid the interference of alternating force, more reasonable structure, and have good mechanical property and biocompatibility concurrently.
The purpose of this utility model is achieved in that
An implant dental structure, is characterized in that: it forms by planting tooth body, maintenance platform, Compress Spring and cushion pad; Described top of planting tooth body embeds and is provided with ring-type porous tantalum product, and its porosity is 60% ~ 70%; This is planted tooth body inside and is provided with the through hole running through up and down; The surface of this through hole middle and upper part is provided with regular screw threads; Described body middle part outer surface of planting tooth body is also symmetrically arranged with discontinuity screw thread; Described maintenance platform bottom is threaded rod, and this threaded rod coordinates with the regular screw threads of planting the inner surface of tooth body; On described maintenance platform, be provided with cushion pad; Described Compress Spring is fixed by socket in the lower surface outside of planting tooth body.
Through what adopt that the ring-type porous tantalum product of above-mentioned porosity embeds, plant tooth body, can meet the structural mechanical property requirement 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, when greatly having improved biocompatibility, also well met its mechanical property, improved service life and implanted comfort level, having increased stability and anti-verticity after artificial prosthesis is implanted.This porous tantalum product specifically can adopt the preparations such as foam dipping method, die pressing.
Further, the body middle and lower part outer surface of planting tooth body between above-mentioned discontinuity screw thread is also provided with axial cutting edge.To have realized when it is pierced resistance less for the tooth body of planting of this structure setting, pierces process convenient, and the misery that patient suffers will reduce greatly.
Further, the top of above-mentioned maintenance platform is Rotary-table or cylinder, and one-body molded with the threaded rod of above-mentioned maintenance platform bottom.The maintenance platform of this Rotary-table shape or cylindrical shape, can install cushion pad in order to Corresponding matching, and then again corona is installed on cushion pad, has realized the implantation of artificial tooth.
Further, above-mentioned bottom end face of planting tooth body also horizontal distribution have the guiding gutter being communicated with above-mentioned through hole.By increasing guiding gutter in this bottom, can improve greatly the mobility at the broken end of flesh and blood, make itself and porous material better compatible.
Further, also arrange porosely in the top of above-mentioned maintenance platform, on above-mentioned cushion pad, also correspondence arranges porose.By being respectively arranged with hole in the top at maintenance platform He on cushion pad, can in application, adopt the modes such as inserted link by the two fixing interlocking together, prevent from coming off.
The utlity model has following beneficial effect:
1, plant tooth body with maintenance platform by being threaded, easily produce self-locking, good stress performance;
2, the discontinuity screw thread that its outer surface of planting tooth body body arranges, has realized with alveolar bone and being firmly connected, and further had the effects such as the sinking of preventing and rotation, has strengthened and has been connected with the firm of alveolar bone;
3, the bottom that employing is fixed on alveolar bone by Compress Spring one end, to continue applying active force to planting tooth body, is fixed on alveolar bone, has guaranteed the close contact all the time of the two; In use, if because external force makes to plant tooth body to be become flexible, Compress Spring makes it again keep close contact by elastic force, and then has guaranteed fixed effect;
4, plant and in tooth body, adopted porous tantalum product, well met its mechanical property, also greatly increase the biocompatibility of this implant dental structure simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted;
5, at the bottom end face of planting tooth body by increasing the guiding gutter of the horizontal distribution being communicated with through hole, greatly improved the mobility of the materials such as flesh and blood broken end, make it and be provided with porous tantalum product to plant tooth body better compatible;
6, by add cushion pad between artificial tooth and maintenance platform, scalable denture upper jaw power is distributed, and has avoided periodontal trauma, has alleviated the load of canine implant, has improved canine implant success rate, and has increased its service life; And further at it, on the two, offer respectively porosely, make both interlockings together, prevent from coming off;
7, by axial cutting edge is set, when it is pierced, resistance is less, pierces process convenient, and the misery that patient suffers will reduce greatly.
