Description

A kind of canine implant

Technical field

This utility model relates to oral cavity implant tooth, relates in particular to a kind of canine implant.

Background technology

The Dental Implant that oral tooth implantation operation at present adopts mostly includes plants tooth body, retained abutment and artificial tooth.Plant tooth body and imbed in advance after dental bed, its top refills and establishes retained abutment, and this retained abutment exposes to dental bed surface and artificial tooth is installed, and realizes the implantation of artificial tooth with this.

Wherein, plant and between tooth body and retained abutment, be mostly regular screw threads and be connected, easily exist and connect defective tightness, and be easy to cause impurity to enter in connecting thread gap, and then affect being fixedly connected with of the two; Between its retained abutment and artificial tooth, be usually that simple plug-in type connects, the anti-axial-rotation of this connected mode is poor, and exist connect not firmly, easily loosening and hold caducous problem.Simultaneously, on structure arranges, there is certain defect in existing Dental Implant, cause it after implantation, can not plant the sclerotin weakness such as tooth body bottom, add again that other plant the material of tooth steadiness to increase as bone grafting material, biotic factor 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, existing canine implant also exist with body bone tissue between while being connected steadiness, mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.

Utility model content

The purpose of this utility model is to provide a kind of canine implant, this canine implant can closely be connected retained abutment with artificial tooth in real time, and realization is simultaneously planted tooth body and is connected with retained abutment sealing, is convenient to material and imports or discharge, simple and reasonable, and have good biocompatibility concurrently.

The purpose of this utility model is achieved in that

A kind of canine implant, it includes plants tooth body, retained abutment and artificial tooth, it is characterized in that: in described retained abutment head, be provided with through hole, in this through hole, be provided with spring, both ends of the spring is respectively arranged with slide block; On this slide block, be provided with the groove of mounting spring; In described artificial tooth, correspondence is provided with the caulking groove that described slide block is installed; The described tooth body of planting adopts porous tantalum product, and its porosity is 60% ~ 70%; The described tooth body inside of planting is provided with perforation, and the inner surface of tooth body of planting of this perforation place is provided with gas thread; Described retained abutment bottom is threaded rod, this threaded rod and the described gas thread corresponding matching of planting the inner surface setting of tooth body; Described bottom end face of planting tooth body is also provided with the guiding gutter being communicated with described perforation.

Through adopting the porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of tooth body in artificial growth dental structure, 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: adopt the tooth physical ability of planting of porous tantalum product that bone is grown 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.

Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.This slide block also can be set to the object that other sides such as right angle trigonometry body are inclined-plane.

Above-mentioned retained abutment head is cuboid, and with artificial tooth corresponding matching, can further increase anti-axial-rotation.

The quantity of above-mentioned spring is preferably two, and for arranging up and down.Above-mentioned slide block is provided with two grooves of arranging up and down corresponding to mounting spring place.

Above-mentioned guiding gutter is horizontal distribution, and can also be set to multiple.Setting up guiding gutter 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 bottom, thereby increase the stability being connected with sclerotin, and can also greatly improve the broken end of flesh and blood simultaneously and wait the mobility of materials, make it and be set to porous tantalum product to plant tooth body better compatible.

In above-mentioned perforation, bottom is also provided with extension spring; One end of this extension spring is connected with described threaded rod lower end.Bottom by extension spring one end being fixed on to alveolar bone is to continue that retained abutment is applied to elastic force, be fixed in the perforation of planting tooth body inside, ensured 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 ensured fixed effect.

In this utility model, planting tooth body and retained abutment and adopt gas thread, is specifically the gas thread of 55 ° as tooth form angle, Corresponding matching, and its sealing and good stress performance, easily produce self-locking, avoided impurity to enter in screw thread, it is planted tooth body itself and adopts porous tantalum product, well meet its mechanical property, also greatly increased the biocompatibility of this canine implant simultaneously, improve service life and implanted comfort level, stability and anti-verticity after this artificial prosthesis is implanted are increased, simultaneously, be processed with slide block through hole by retained abutment head, and the side that can slide in through hole of configuration be inclined-plane slide block and spring, and caulking groove is set on artificial tooth, having realized retained abutment and artificial tooth keeps fitting tightly, thereby play well anti-axially movable effect, and anti-loosening and effect that come off.In addition, the guiding gutter being further communicated with by increase and perforation 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 increase the stability being 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.
