Description
Technical field
The present invention relates to oral cavity canine implant, particularly relate to a kind of Dental Implant.
Background technology
The Dental Implant that current oral tooth implantation operation adopts mostly includes plants tooth body, retained abutment and artificial tooth.Plant after tooth body imbeds dental bed in advance, refill above it and establish retained abutment, this retained abutment exposes to dental surface and installs artificial tooth, realizes the implantation of artificial tooth with this.
Wherein, be usually that simple plug-in type connects between retained abutment and artificial tooth, the anti-axial-rotation of this connected mode is poor, and existence connects not firmly, easily loosens and hold caducous problem; Meanwhile, it is planted, and tooth body is standing counts cylindricality or irregularly shaped, and it is poor with steadiness when being connected between body bone tissue, and the irregularly shaped body had also is difficult to processing and manufacturing.In addition, there is certain defect in existing Dental Implant on vibrational power flow, cause its mechanical property and biocompatibility poor, after long-time use, there will be repulsion with tissue, and affect the problems such as its service life.
Summary of the invention
The object of the present invention is to provide a kind of Dental Implant, this Dental Implant in real time by retained abutment and corona compact siro spinning technology, can will plant tooth body and alveolar bone compact siro spinning technology simultaneously, simple and reasonable, and has good biocompatibility concurrently.
The object of the present invention is achieved like this:
A kind of Dental Implant, it includes plants tooth body, retained abutment and artificial tooth, it is characterized in that: be provided with through hole in described retained abutment head, be provided with spring in this through hole, both ends of the spring is respectively arranged with slide block; This slide block is provided with the groove of mounting spring; In described artificial tooth, correspondence is provided with the caulking groove installing described slide block; Described tooth body of planting adopts porous tantalum product, and its porosity is 60% ~ 70%; Described tooth body of planting is made up of cervical region, middle part and afterbody, and its center 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, to realize itself and alveolar bone reliably compact siro spinning technology.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 to make Bone Ingrowth and structure of growing in being formed, thus organically combine as a whole with body bone tissue, while substantially increasing biocompatibility, also well meet its mechanical property, improve service life and implant comfort level, adding the stability after artificial prosthesis implantation and anti-rotation performance.
Above-mentioned slide block, is excellently less than the right-angled trapezium body of lower surface area for upper surface area.It is the object on inclined-plane that this slide block also can be set to other sides such as right angle trigonometry body.
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 arrange up and down.Above-mentioned slide block corresponds to mounting spring place and is provided with about two grooves of arranging.
Further, above-mentioned tooth body of planting is shaft-like, and its cervical region is consistent with the diameter at middle part; The diameter of its afterbody compared with cervical region or middle part short.The tooth body of planting of this vibrational power flow achieves and is firmly connected with alveolar bone, and has effects such as preventing sinking further.
Above-mentioned tooth body inside of planting is provided with groove, and this side of planting tooth body interior grooves is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, and the regular screw threads that this threaded rod is arranged with the side of planting tooth body interior grooves place coordinate, and are fixedly connected with the self-locking realizing the two, and good stress performance.
In the present invention, retained abutment head is processed with through hole, and configuration can in through hole sliding slider, along with artificial tooth down slides, promote slide block to 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, enable slide block keep fitting closely with the caulking groove on artificial tooth, thus play the well anti-effect moved axially, and anti-loosening and effect that is that come off; Meanwhile, the outer surface of planting in the middle part of tooth body is also provided with regular screw threads, further enhancing and is connected with the firm of alveolar bone; And tooth body employing porous tantalum product itself will be planted further, well meet its mechanical property, also greatly increases the biocompatibility that this plants dental structure simultaneously, improve service life and implant comfort level, add the stability after the implantation of this artificial prosthesis and anti-rotation performance.

Detailed description of the invention
Be below preferred embodiment of the present invention, and be not intended to limit protection scope of the present invention.
As shown in figures 1-4: a kind of Dental Implant, it include plant tooth body 1, retained abutment 2 that head is cuboid and artificial tooth 3; Rectangular through holes 4 is provided with in its retained abutment 2 head, in this through hole 4, middle part is provided with two springs 5 of arranging up and down, spring about 5 two ends 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 being provided with mounting spring 5 on this slide block 6; In artificial tooth 3, correspondence is provided with the caulking groove 7 installing slide block 6; It is planted tooth body 1 and adopts porous tantalum product, and its porosity is 60% ~ 70%; This is planted, and tooth body 1 is shaft-like for what be made up of cervical region 11, middle part 12 and afterbody 13, and in the middle part of it, 12 outer surfaces are set to regular screw threads 14, and its cervical region 11 is consistent with the diameter at middle part 12, the diameter of its afterbody 13 compared with cervical region 11 or middle part 12 short; 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 bottom is threaded rod 9, this threaded rod 9 with plant the regular screw threads that tooth body 1 interior grooves 8 side arranges and coordinate, be fixedly connected with the self-locking realizing the two; This head is the retained abutment 2 of cuboid, adopt medical titanium alloy make, and with artificial tooth 3 corresponding matching, namely achieve the implantation of artificial tooth.
By retained abutment 2 head is processed with through hole 4, and configure the slide block 6 that can slide in through hole 4, along with artificial tooth 3 down slides, promote slide block 6 to move in 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 fitting closely with the caulking groove 7 on artificial tooth 3, thus play the well anti-effect moved axially, and anti-loosening and effect that is that come off; And its outer surface of planting in the middle part of tooth body 1 12 is also provided with regular screw threads 14, further enhancing and is connected with the firm of alveolar bone.
