Description

Plant dental structure for one kind

Technical field

This utility model relates to oral cavity canine implant, relates in particular to one kind and plants dental structure.

Background technology

What at present oral tooth implantation operation adopted plant, and dental structure 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 simple plug-in type connected mode, the anti-axial-rotation of this connected mode is poor, and exist connect not firmly, easily loosening and hold caducous problem.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.Simultaneously existing plant dental structure 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 one kind to plant dental structure, and this is planted dental structure and can in real time retained abutment be closely connected with corona, is convenient to material and imports or discharge, simple in structure, and has good biocompatibility concurrently.

The purpose of this utility model is achieved in that

Plant a dental structure, 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; 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; 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 in the mechanical property requirements of planting in dental structure, 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.

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

The inner surface of tooth body of planting of above-mentioned perforation place is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, and this threaded rod coordinates with these regular screw threads of planting the inner surface setting of tooth body, be fixedly connected with the self-locking that realizes the two, and good stress performance.

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 retained abutment head is processed with through hole, and configuration can be in through hole sliding slider, along with artificial tooth is toward lower slider, promote slide block moves in through hole, artificial tooth moves into place in the caulking groove on rear embedding 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 the guiding gutter being further communicated with by increase and perforation at the bottom end face of planting tooth body, realize bone grafting material, other materials of planting tooth steadiness to increase such as biotic factor are introduced, be evenly distributed on sclerotin weakness such as planting tooth body bottom, 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 its be set to porous tantalum product to plant tooth body better compatible.In addition, it is planted tooth body itself and adopts porous tantalum product, well met its mechanical property, has also greatly increased this simultaneously and plant the biocompatibility of dental structure, improve service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted.

Detailed description of the invention

Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.

As shown in Figures 1 to 3: plant dental structure for one kind, it includes plants retained abutment 2 and the artificial tooth 3 that tooth body 1, head are cuboid; In its retained abutment 2 heads, be provided with rectangular through holes 4, this interior middle part of through hole 4 is provided with a spring 5, and spring 5 two ends, left and right are respectively arranged with a slide block 6; Slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area; The interior correspondence of artificial tooth 3 is provided with the caulking groove 7 that slide block 6 is installed; It is planted tooth body 1 and adopts porous tantalum product, and its porosity is 60% ~ 70%; It is planted tooth body 1 inside and is provided with the perforation 8 running through up and down, and this bottom end face of planting tooth body 1 also horizontal distribution have the guiding gutter 10 being communicated with this perforation 8; The inner surface of tooth body 1 of planting at these perforation 8 places is provided with regular screw threads; Its retained abutment 2 bottoms are threaded rod 9, and this threaded rod 9 coordinates with these regular screw threads of planting tooth body 1 inner surface setting, is fixedly connected with the self-locking that realizes the two; This head is the retained abutment 2 of cuboid, adopt medical titanium alloy make, and with artificial tooth 3 corresponding matching, realized the implantation of artificial tooth.

By retained abutment 2 heads are processed with to through hole 4, and configuration can be at the slide block 6 of through hole 4 interior slips, along with artificial tooth 3 is toward lower slider, promote slide block 6 to the interior movement of through hole 4, after artificial tooth 3 moves into place, slide block 6 embeds in the caulking groove 7 on artificial tooth 3, now by the effect of spring 5, make slide block 6 can keep with artificial tooth 3 on caulking groove 7 laminating closely, thereby play well anti-axially movable effect, and anti-loosening and effect that come off.
