Description

A kind of inserted type Dental Implant

Technical field

This utility model relates to oral cavity canine implant, relates in particular to a kind of inserted type Dental Implant.

Background technology

The Dental Implant structure 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, between retained abutment and artificial tooth, be usually that simple plug-in type connects, the anti-axial-rotation of this connected mode is poor, and has the problem that connects not firmly, easily becomes flexible, comes off; It is planted and between tooth body and retained abutment, is mostly regular screw threads and is connected, and easily exists and connects defective tightness, and be easy to cause impurity to enter in connecting thread gap, and then affect being fixedly connected with of the two.

In addition, 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.Meanwhile, existing Dental Implant also exist 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 inserted type Dental Implant, this Dental Implant can be in real time by closely chimeric to retained abutment and corona, and realization is simultaneously planted tooth body and is connected with retained abutment sealing, is convenient to material and imports or discharge, rational in infrastructure, and have good biocompatibility concurrently.

The purpose of this utility model is achieved in that

A kind of inserted type Dental Implant, it includes plants tooth body, retained abutment and artificial tooth, it is characterized in that: described retained abutment head is provided with groove on one side, in this groove, is provided with spring, and spring arranged outside has slide block; 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%, and this is planted tooth body inside and is provided with the perforation running through up and down; 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 described gas thread corresponding matching; Described bottom end face of planting tooth body is also provided with the guiding gutter being communicated with described perforation.

The porous tantalum product of above-mentioned porosity, can meet this and plant tooth body and plant the mechanical property requirements in dental structure at this, is 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, or the object of other shapes.

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

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, and the stability that increase is 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.

This utility model will be processed with groove and be provided with spring on retained abutment head one side, configuration can be at the slide block of this groove one side activity again, so that its mating reaction and play the fixation that is similar to latch dead bolt---along with artificial tooth is toward lower slider, promote slide block Compress Spring moves in groove, after artificial tooth moves into place, slide block falls into the caulking groove on artificial tooth, now by the effect of spring, make slide block can keep with artificial tooth on caulking groove laminating closely, thereby play well anti-axially movable effect, and anti-loosening and effect that come off; And further will plant tooth body itself and adopt porous tantalum product, well meet its mechanical property, also greatly increase the biocompatibility that this plants dental structure simultaneously, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted.In addition, the guiding gutter of the horizontal distribution being communicated with perforation 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.
