The purpose of this utility model is achieved in that
A tooth 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 of planting is comprised of cervical region, middle part and afterbody, and its middle part outer surface is set to regular screw threads; 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.
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.
Further, the above-mentioned tooth body of planting is shaft-like, and the diameter at its cervical region and middle part is consistent; The diameter of its afterbody is short compared with cervical region or 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.
Above-mentioned side of planting the inner perforated middle and upper part of tooth body is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, this threaded rod and this regular screw threads corresponding matching, and then the self-locking that realizes the two is fixedly connected with, and good stress performance.
Retained abutment in this utility model and artificial tooth are chimeric closely, have played well anti-moving axially, and anti-loosening and effect that come off; The outer surface of planting tooth body middle part is also provided with regular screw threads, has further strengthened with the firm of alveolar bone and has been connected; Also by perforation and guiding gutter, realize the material introducing that the increases such as biotic factor are planted to tooth steadiness and be distributed in sclerotin weakness such as planting tooth body bottom, and increased the stability being connected with sclerotin.In addition, also will plant tooth body and adopt porous tantalum product, well meet its mechanical property, and also greatly increase this simultaneously and planted the biocompatibility of dental structure, improved service life and implanted comfort level, having increased stability and anti-verticity after this artificial prosthesis is implanted.

The specific embodiment
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: a kind of tooth implant, 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 two springs 5 of arranging up and down, spring 5 two ends, left and right are respectively arranged with slide block 6, this slide block 6 is less than the right-angled trapezium body of lower surface area for upper surface area, and corresponding two grooves 10 that are provided with mounting spring 5 on this slide block 6; 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 shaft-like for what be comprised of cervical region 11, middle part 12 and afterbody 13 that this plants tooth body 1, and its middle part 12 outer surfaces are set to regular screw threads 14, and its cervical region 11 is consistent with the diameter at middle part 12, and the diameter of its afterbody 13 is short compared with cervical region 11 or middle part 12; This is planted tooth body 1 inside and is provided with the perforation 8 running through up and down; The bottom end face of planting tooth body 1 is also provided with the guiding gutter 15 being communicated with this perforation 8; This side of boring a hole 8 middle and upper parts is provided with regular screw threads; Retained abutment 2 bottoms are threaded rod 9, this threaded rod 9 and the regular screw threads corresponding matching of planting tooth body 1 inner perforated 8 sides, middle and upper part and arranging, and then the self-locking that realizes the two is fixedly connected with; This head is the retained abutment 2 of cuboid, adopts medical titanium alloy to 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, in the caulking groove 7 that slide block 6 embeds 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; And it plants the porous tantalum product that tooth body 1 adopts above-mentioned porosity, can meet the mechanical property requirements in tooth implant structure, to realize it, is closely connected reliably with alveolar bone.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, 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.
