Description
Technical field
This utility model relates to manual tooth planting, particularly relates to a kind of artificial artificial tooth.
Background technology
It is similar to natural teeth in function, sensation, form and result of use that dentistry plants artificial artificial tooth, is thus described as " the good teeth of the 3rd width of the mankind ".But existing artificial artificial tooth, mostly deposit be connected built on the sand with alveolar bone after the implantation, easy loose or dislocation; Biocompatibility is poor, implantation is rear and tissue easily produces repulsion, and service life is shorter; Be connected firm not with between artificial tooth; Implant most advanced and sophisticated unbalance stress, affect the problems such as postoperative impression, thus improvement urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of artificial artificial tooth, and this artificial artificial tooth and alveolar bone stable connection, better, the postoperative comfort of biocompatibility are better.
The purpose of this utility model is achieved in that
A kind of artificial artificial tooth, is characterized in that: it is made up of implantation body, spring, jacking block, slide block, artificial tooth and ring-type porous tantalum product; Described implantation body is provided with through perforation, and arrange spring in the middle of perforation, both ends of the spring arranges jacking block respectively; The lateral ends of described jacking block is pointed bur; The body appearance of described implantation body is provided with annular recess, and is attached with one deck ring-type porous tantalum product in annular recess; Be provided with through hole in the head of described implantation body, have spring in through hole, both ends of the spring is arranged with slide block; In described artificial tooth, correspondence is provided with the caulking groove installing slide block; The afterbody of described implantation body is smooth hemisphere face.
As further optimization, the cervical region appearance of above-mentioned implantation body is set to concaved circular cambered surface in annular.
Above-mentioned ring-type porous tantalum product, its porosity is 50% ~ 60%.This ring-type porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
Above-mentioned jacking block is specially convex shape, and lateral ends is pointed bur.This jacking block, also can be set to the object that other conventional one end such as cone are pointed bur.
Above-mentioned slide block may be selected to be the right-angled trapezium body that upper surface area is less than lower 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, or the object of other shapes.
This utility model has following beneficial effect:
1, the agent structure of its implantation body is that a simplification is overall, is convenient to processing;
2, by arranging spring and slide block in the through hole of implantation body's head, in conjunction with correspondence, caulking groove is set in artificial tooth, achieve in the caulking groove by the effect of elastic force slide block is mounted in after artificial tooth is installed in artificial tooth, and then the stable connection achieved between implantation body and artificial tooth, and the rotation of artificial tooth can be prevented further, its connection is more reliable and more stable;
3, by unique structural design, concaved circular cambered surface in annular is defined in the cervical region appearance of implantation body, after implanting in this annular concaved circular cambered surface healing district in order to circumferentially distribute, be convenient to implant rear osseous tissue enter to this healing district indent director, substantially reduce the restore cycle, add the compact siro spinning technology of this artificial structure and alveolar bone, and the displacement that not easily gets loose;
4, by adhering to ring-type porous tantalum product in the annular recess of implantation body's body appearance, define porous adhesive layer, while meeting mechanical property requirements, achieve body bone tissue after implanting to grow into this loose structure, and structure of growing in inwardly filling and then being formed, it is one overall for achieving that artificial prosthesis and osseous tissue organically combine, considerably increase the biocompatibility of structure entirety, implant after stability and anti-rotation performance, improve service life and implant comfort level;
5, the afterbody of its implantation body is designed to smooth hemisphere face, increases and implants bottom lifting surface area, be beneficial to the uniform stressed bottom implantation body, improve postoperative comfort;
6, by arranging the jacking block that spring and one end are pointed bur in perforation through in implantation body, gone out by pointed bur one end thruster outward of the effect of elastic force by jacking block after achieving implantation, and be tightly fixed in alveolar bone, namely achieve the compact siro spinning technology of this artificial artificial tooth and human body alveolar bone, combine firmly.

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.
Embodiment 1
As shown in figures 1-4: a kind of artificial artificial tooth, it is made up of implantation body 1, spring 2, jacking block 3, slide block 4, artificial tooth 5 and ring-type porous tantalum product 6; Its implantation body 1 is provided with the perforation 7 of lateral direction penetrating, and arrange spring 2 in the middle of perforation 7, spring 2 two ends arrange jacking block 3 respectively; This jacking block 3 is specially convex shape, and lateral ends is pointed bur; The body appearance of its implantation body 1 is provided with ring-type rectangular recess 8, and in ring-type rectangular recess 8, being attached with the ring-type porous tantalum product 6 that a layer porosity is 50% ~ 55%, this ring-type porous tantalum product 6 specifically can with reference to employing method preparation as described in patent 201110296515.7; Cervical region 12 appearance of its implantation body 1 is concaved circular cambered surface in annular, and afterbody 13 is smooth hemisphere face; Be provided with through hole 10 in the head 9 of its implantation body 1, have spring 2 in through hole 10, spring 2 two ends each one are provided with slide block 4 respectively, and this slide block 4 is less than the right-angled trapezium body of lower surface area for upper surface area; In its artificial tooth 5, correspondence is provided with the caulking groove 11 installing slide block 4.
First on alveolar bone, an installing hole is got out with instrument during implantation, insert in the hole implantation body 1 appropriate depth again, namely jacking block 3 outside spring 2 stretches out under spring force, the pointed bur of its lateral ends, namely to penetrate in osseous tissue and tightly build-in wherein, namely achieves the compact siro spinning technology of it and human body alveolar bone.
When artificial tooth 5 is installed, in the through hole 10 of implantation body 1 head 9, place the slide block 4 at spring 2 and its two ends in advance, and then artificial tooth 5 is installed to also pressing downwards on implantation body 1 head 9; When being installed to suitable position, namely slide block 4 is mounted in the caulking groove 11 in artificial tooth 5 under the effect of elastic force, also namely achieves the stable connection between implantation body 1 and artificial tooth 5, and prevents the rotation of artificial tooth 5, and its connection is more reliable and more stable.
In its structure, can regulate in conjunction with firmness according to spring rate, convenient and reliable.
