Description

A kind of Dental Implant

Technical field

This utility model relates to oral cavity canine implant, relates in particular to a kind of Dental Implant.

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, plant the standing cylindricality or irregularly shaped of counting of tooth body, it with body bone tissue between while being connected steadiness poor, and can not be again at sclerotin weakness such as bottoms after implantation, then add as biotic factor etc. other to increase the material of planting tooth steadiness; Between its retained abutment and artificial tooth, often for card edge type connects, the anti-axial-rotation of this connected mode is poor, and has the problem that connects not firmly, easily becomes flexible, comes off.

In addition, existing Dental Implant 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 a kind of Dental Implant, 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, is also convenient to import the material that tooth steadiness is planted in increase, rational in infrastructure, and have good biocompatibility concurrently.

The purpose of this utility model is achieved in that

A 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; This is planted tooth body and is comprised of cervical region, middle part and afterbody, and its cervical region and afterbody all adopt porous tantalum product, and its porosity is 60% ~ 70%, and its middle part outer surface is regular screw threads; This is planted tooth body inside and is provided with the perforation running through up and down.

Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.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.

Above-mentioned side of planting tooth body inner perforated middle and upper part 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 inner perforated middle and upper part arranges, and then the self-locking that realizes the two is fixedly connected with, and good stress performance.

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.

Further, above-mentioned cervical region and afterbody of planting tooth body, realizes and being fixedly connected with of above-mentioned middle part of planting tooth body through bonding or welding respectively.Its connected mode is solid and reliable.

Retained abutment in this utility model and artificial tooth laminating closely, have been 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; Cervical region and the afterbody of planting tooth body are adopted to porous tantalum product, well met its mechanical property, also greatly increase this simultaneously and planted the biocompatibility of dental structure, improved service life and implanted comfort level, increased stability and anti-verticity after this artificial prosthesis is implanted.In addition, also realized the material that the increases such as biotic factor are planted to tooth steadiness and introduced and to be distributed in sclerotin weakness such as planting tooth body bottom, and increased the stability being connected with sclerotin, make it and be set to porous tantalum product to plant tooth body better compatible.

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 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, 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, 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; This plants the rhabodoid of tooth body 1 for being comprised of cervical region 11, middle part 12 and afterbody 13, its middle part 12 adopts medical titanium alloy product, cervical region 11 and afterbody 13 all adopt porous tantalum product, its porosity is 60% ~ 70%, and cervical region 11 and afterbody 13 are specifically realized and to be fixedly connected with this middle part 12 of planting tooth body 1 through laser weld respectively; It is the regular screw threads 14 of 60 ° that its middle part 12 outer surfaces are provided with tooth form angle, 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; 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 the porous tantalum product of above-mentioned porosity, can meet this and plant the mechanical property requirements of tooth body structure in Dental Implant, 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 cervical region of planting tooth body 1 11 and the afterbody 13 of porous tantalum product can make bone grow 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.
