Description

A kind of canine implant plant 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 kind of implant component of planting of canine implant.

Background technology

Canine implant is the best method of repairing at present oral cavity inner teeth gear disappearance.Dental implant surgical of the prior art, normally plants tooth body by one and directly imbeds in advance dental bed, after above planting tooth body, install a retained abutment separation and that expose to dental bed surface, a corona is finally installed in this retained abutment again again, to realize the implantation of artificial tooth.

But, plant tooth body and in use can be subject to for a long time the effect of alternating force, particularly work as Dental Implant when mounted, if move past to words lateral deviation many, easily occur in a short time loosening, and because existing structural design of planting tooth body member 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.There is certain defect in implant implant component of the prior art, it plants tooth body and retained abutment syndeton defective tightness, and be easy to cause impurity to enter in screw thread, affect being fixedly connected with of the two, and its plant between tooth body and tissue, also exist in conjunction with defective tightness reliable, easily produce the problems such as loosening, Dental Implant can not planted the most advanced and sophisticated sclerotin weakness that waits of tooth body after implantation simultaneously, add again as bone grafting material, other plant the material of tooth steadiness to increase biotic factors etc., and the materials such as the broken end of the flesh and blood that may exist in its structure are also difficult for discharging, poor fluidity between material.In addition, it is poor that in existing design also usually there is mechanical property and biocompatibility in implant implant component, there will be repulsion, and affect the problems such as its service life after long-time use with tissue.

Utility model content

The purpose of this utility model is to provide a kind of implant component of planting of canine implant, the planting implant component and can closely be connected with alveolar bone planting tooth body in real time of this canine implant, the sealing of its connection and good stress performance, can avoid preferably it to be subject to the interference of alternating force, and being convenient to material imports or discharges, have simple in structure, intensity is higher, has the characteristics such as good biocompatibility concurrently.

The purpose of this utility model is achieved in that

Canine implant plant an implant component, it is characterized in that: it forms by planting tooth body, retained abutment and extension spring; The described tooth body inside of planting is provided with the through hole running through up and down; To be provided with tooth form angle be the gas thread of 55 ° on the inner surface of tooth body of planting of this through hole middle and upper part, and the tooth body inside of planting of this through hole bottom is provided with extension spring; Described retained abutment bottom is threaded rod, and this threaded rod is connected with one end of described extension spring, and with described to plant tooth form angle that the inner surface of tooth body arranges be the gas thread corresponding matching of 55 °; This plants tooth body is the clava being made up of cervical region, middle part and afterbody, and its cervical region and afterbody all adopt porous tantalum product, and its porosity is 60% ~ 70%; Described tail end face of planting tooth body also horizontal distribution has the guiding gutter being communicated with described through hole.

Adopt the cervical region of planting tooth body and the afterbody of the porous tantalum product of above-mentioned porosity, can meet its mechanical property requirements in the structure of planting implant component, be closely connected reliably with alveolar bone to realize it.This porous tantalum product can adopt the preparations such as foam dipping method, die pressing.Through the discovery that studies for a long period of time: the cervical region of planting tooth body and the afterbody that adopt porous tantalum product, can make bone grow into and the structure of growing in forming, thereby organically combine as a whole with body bone tissue, 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.Simultaneously, can realize other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor are introduced, are evenly distributed on sclerotin weakness such as planting tooth body afterbody by setting up guiding gutter, and the stability that increase is connected with sclerotin, and can greatly improve the mobility of the materials such as the broken end of flesh and blood, make it and be set to porous tantalum product to plant tooth body better compatible.In addition,, by being the gas thread Corresponding matching of 55 ° by threaded rod and the tooth form angle of planting the inner surface setting of tooth body, its sealing and good stress performance, easily produce self-locking, avoided impurity to enter in screw thread.

Further, the outer surface at above-mentioned middle part of planting tooth body is gas thread; The diameter of its afterbody is narrow compared with cervical region and middle part.The tooth body of planting 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.

The top of above-mentioned retained abutment is Rotary-table, and one-body molded with the threaded rod of above-mentioned retained abutment bottom.The Rotary-table on its top can be installed corona in order to Corresponding matching, and has realized the implantation of artificial tooth.

Further, above-mentioned cervical region and afterbody of planting tooth body, realizes and being fixedly connected with of above-mentioned middle part of planting tooth body through bonding or welding respectively.Its connected mode is solid and reliable.

Further, above-mentioned guiding gutter can be set to multiple.

The utlity model has following beneficial effect:

1, as cervical region and the afterbody of planting the non-stress position in tooth body structure, all adopt porous tantalum product, well meet and guaranteed its mechanical property, also greatly increased the biocompatibility that this plants implant component entirety simultaneously, improve service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted;

The guiding gutter of the horizontal distribution 2, being communicated with through hole by increase at the bottom end face of planting tooth body, realize sclerotin weakness such as planting tooth body bottom has been introduced, has been evenly distributed on to other materials of planting tooth steadiness to increase such as bone grafting material, biotic factor, and the stability that increase is connected with sclerotin, and can greatly improve the mobility of the materials such as the broken end of flesh and blood, make it and be set to porous tantalum product to plant tooth body better compatible;

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

4, planting tooth body and retained abutment, to adopt tooth form angle be the gas thread Corresponding matching of 55 °, and its sealing and good stress performance, easily produce self-locking, avoided impurity to enter in screw thread.
