Description
Technical field
The present invention relates to oral cavity canine implant, particularly relate to a kind of tooth implant.
Background technology
The tooth 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.
Often for card edge type connects between its retained abutment and artificial tooth, the anti-axial-rotation of this connected mode is poor, and there is the problem connecting and not firmly, easily loosen, come off; Meanwhile, its structure is poor with steadiness when being connected between body bone tissue; After the implantation can not again at sclerotin weakness such as bottoms, then add as biotic factor etc. other to increase the material of planting tooth steadiness.
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 tooth implant, this Dental implantion physical ability in real time by retained abutment and corona, plant tooth body and alveolar bone compact siro spinning technology, simple and reasonable, be also convenient to import the material increasing and plant tooth steadiness, and have good biocompatibility concurrently.
The object of the present invention is achieved like this:
A kind of tooth 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; This is planted tooth body inside and is provided with the perforation run through up and down; Described bottom end face of planting tooth body is also provided with and the described guiding gutter be communicated with of boring a hole.
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 side of planting the inner perforated middle and upper part of tooth body is provided with regular screw threads; Above-mentioned retained abutment bottom is threaded rod, this threaded rod and this regular screw threads corresponding matching, and then the self-locking both realizing is fixedly connected with, and good stress performance.
Retained abutment in the present invention is chimeric with artificial tooth closely, serves well anti-moving axially, and anti-loosening and effect that is that come off; 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; Also achieve the material introducing of the increases such as biotic factor being planted tooth steadiness by perforation and guiding gutter and be distributed in sclerotin weakness such as planting tooth body bottom, and add the stability be connected with sclerotin.In addition, also will plant tooth body and adopt porous tantalum product, and well meet its mechanical property, also greatly increases the biocompatibility that this plants dental structure simultaneously, improve service life and implant comfort level, adding 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 to 3: a kind of tooth 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; This is planted tooth body 1 inside and is provided with the perforation 8 run through up and down; The bottom end face of planting tooth body 1 is also provided with the guiding gutter 15 be communicated with this perforation 8; The side of this perforation 8 middle and upper part is provided with regular screw threads; Retained abutment 2 bottom is threaded rod 9, this threaded rod 9 and the regular screw threads corresponding matching of planting side, tooth body 1 inner perforated 8 middle and upper part and arranging, and then the self-locking both realization is fixedly connected with; 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 it plants the porous tantalum product that tooth body 1 adopts above-mentioned porosity, can meet the mechanical property requirements in tooth 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.
