Description
Technical field
This utility model relates to oral cavity canine implant, relates in particular to a kind of Dental 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 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 exist connect not firmly, easily loosening and hold caducous problem; Meanwhile, it plants the standing cylindricality or irregularly shaped of counting of tooth body, it with body bone tissue between while being connected steadiness poor, the irregularly shaped body having is also difficult to processing and manufacturing.In addition, there is certain defect in existing Dental Implant on structure arranges, and causes its mechanical property and biocompatibility poor, 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 a kind of Dental Implant, and this Dental Implant can closely be connected retained abutment with corona in real time, will plant tooth body simultaneously and closely be connected with alveolar bone, simple and reasonable, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
A kind of Dental 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 made up of cervical region, middle part and afterbody, and its middle part outer surface is set to regular screw threads.
The porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of tooth body in Dental Implant 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 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.
The above-mentioned tooth body inside of planting is provided with groove, and this side of planting tooth body internal recess is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, and this threaded rod coordinates with the regular screw threads that the side of planting tooth body internal recess place arranges, be fixedly connected with the self-locking that realizes the two, and good stress performance.
In 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 and move in through hole, after artificial tooth moves into place, slide block embeds in 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; Meanwhile, 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; 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.

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 Fig. 1～4: a kind of Dental 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 made up 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; Plant tooth body 1 inside and be provided with groove 8, the side of this groove 8 is provided with regular screw threads; Its retained abutment 2 bottoms are threaded rod 9, and this threaded rod 9 coordinates with the regular screw threads of planting the 1 internal recess 8 sides settings of tooth body, 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; And its outer surface of planting tooth body 1 middle part 12 is also provided with regular screw threads 14, has further strengthened with the firm of alveolar bone and has been connected.
