Description
Technical field
This utility model relates to oral cavity canine implant, relates in particular to one kind and plants dental structure.
Background technology
At present oral tooth implantation operation adopts plants dental structure and mostly includes and plant 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, 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, there is certain defect in the existing dental structure of planting, cause its mechanical property and biocompatibility poor on structure arranges, and there will be repulsion, and affect the problems such as its service life after long-time use with tissue.
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, 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%.
The porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of tooth body in planting dental 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.
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 above-mentioned tooth body inside of planting is provided with groove, and this groove side is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, this threaded rod with plant the regular screw threads that tooth body interior grooves side arranges and coordinate, with the self-locking that realizes the two, be fixedly connected with, and good stress performance.
This utility model retained abutment head is processed with slide block through hole, and the side that can slide in through hole of the configuration slide block that is inclined-plane, along with artificial tooth is toward lower slider, promote slide block moves in slide block through hole, after artificial tooth moves into place, slide block embeds in the slide block 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 met its mechanical property, also greatly increase this simultaneously and planted the biocompatibility of dental structure, improve service life and implanted comfort level, stability and anti-verticity after this artificial prosthesis is implanted have been increased.

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 Fig. 1～4: 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 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 groove 8, and these groove 8 sides are provided with regular screw threads; Its retained abutment 2 bottoms are threaded rod 9, this threaded rod 9 with plant the regular screw threads that tooth body 1 interior grooves 8 sides arrange and coordinate, with the self-locking that realizes the two, be 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 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.
