Description
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 establishes retained abutment, and this retained abutment exposes to dental bed surface and artificial tooth is installed, and with this, realizes the implantation of artificial tooth.
Wherein, plant tooth body and on structure arranges, have certain defect, it with retained abutment between 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; Meanwhile, 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 to connect not firmly, easily loosening and hold caducous problem.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, and 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, simple and reasonable, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A 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 groove, and this groove side 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 setting of tooth body interior grooves side.
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, to realize it, be 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.
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.
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 retained abutment head is cuboid, and with artificial tooth corresponding matching, can further increase anti-axial-rotation.
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 met 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 have been increased, simultaneously, by retained abutment head, be processed with slide block through hole, 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.

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 canine 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 square through hole 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 a 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 its 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%; This plants tooth body 1 for cylinder, and its inside is provided with groove 8, and it is the gas thread of 55 ° that these groove 8 sides are provided with tooth form angle; Its retained abutment 2 bottoms are threaded rod 9, and this threaded rod 9 and the gas thread corresponding matching of planting the 1 interior grooves 8 sides settings of tooth body, to realize the self-locking seal connection of the two; 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 slide block through hole 4, and the configuration slide block 6 that can be inclined-plane in the side of through hole 4 interior slips, along with artificial tooth 3 is toward lower slider, promote slide block 6 to the interior movement of slide block through hole 4, after artificial tooth 3 moves into place, in the slide block 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.In addition, planting tooth body 1 and retained abutment 2, to adopt tooth form angles 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.
