Description

One Dnetal implant component

Technical field

This utility model relates to Medical oral cavity manual tooth planting's medical apparatus and instruments, relates in particular to a Dnetal implant component.

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, because its structural design is unreasonable, plant tooth body resistance when piercing between body bone tissue larger, pierce process and operation is very inconvenient, the misery that patient suffers is larger; After implanting it with body bone tissue between while being connected steadiness poor, and in use can be subject to for a long time the effect of alternating force, particularly work as Dental Implant when mounted, if to words lateral deviation, move past 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.The defect existing in its structural design, also causes its mechanical property and biocompatibility poor simultaneously, there will be repulsion, and affect its service life after long-time use with tissue.

Utility model content

The purpose of this utility model is to provide a Dnetal implant component, and it is simple in structure that this plants implant component, can avoid preferably the interference of alternating force, and convenient implantation, has good mechanical property and biocompatibility concurrently.

The purpose of this utility model is achieved in that

One Dnetal implant component, is characterized in that: it forms by planting tooth body, maintenance platform and extension spring; The described tooth body of planting adopts 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, and the bottom of this through hole is provided with extension spring; Described maintenance platform bottom is threaded rod, and this threaded rod is connected with one end of described extension spring, and coordinates with described regular screw threads of planting the inner surface of tooth body; Described body middle and lower part outer surface of planting tooth body is also symmetrically arranged with axial cutting edge.

Through adopt above-mentioned porosity porous tantalum product plant tooth body, can meet this and plant the structural mechanical property requirement 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, 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 part outer surface of planting tooth body between above-mentioned axial cutting edge is also provided with discontinuity screw thread.The tooth body of planting of this structure setting has been realized with alveolar bone and being firmly connected, and has and further prevent from and the effect such as rotation.

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, 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 corona in order to Corresponding matching, and then has realized the implantation of artificial tooth.

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, 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;

3, plant tooth body and adopt porous tantalum product, well met its mechanical property, also greatly increased this simultaneously and planted the biocompatibility of implant component, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted;

4, 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 set to porous tantalum product to plant tooth body better compatible;

5, 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;

6, the bottom that employing is fixed on alveolar bone by extension spring one end is to continue that maintenance platform is applied to elastic force, be fixed in the through hole of planting tooth body inside, guaranteed maintenance platform all the time with plant tooth body close contact, by maintenance platform, to planting tooth body, itself apply the effect of power, the bottom that makes to plant tooth body and alveolar bone is close contact all the time simultaneously; In use, if because external force makes to plant tooth body or maintenance platform is loosening, extension spring makes it again keep close contact by elastic force, and then has guaranteed fixed effect.
