Description
Technical field
This utility model relates to manual tooth planting, particularly relates to a kind of plantation artificial tooth.
Background technology
Artificial growth artificial tooth is similar to natural teeth in function, sensation, form and result of use, is thus described as " the good teeth of the 3rd width of the mankind ".But existing artificial growth artificial tooth, implantation is connected built on the sand with alveolar bone afterwards, 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 postoperative impression etc.
Utility model content
The purpose of this utility model is to provide a kind of plantation artificial tooth, and this plantation artificial tooth and human body alveolar bone stable connection, better, the postoperative impression of biocompatibility are better.
The purpose of this utility model is achieved in that
A kind of plantation 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 made up of head, body and afterbody; The body of described implantation body is provided with groove, has spring in groove, and spring outwards has described jacking block; The lateral ends of described jacking block is pointed bur; The body appearance of described implantation body is also 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 respectively equipped 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.
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 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;
4, 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;
5, by arranging non-through groove in implantation body, and the jacking block that spring and lateral ends are pointed bur is set in groove, to achieve pointed for the outside of jacking block bur one end after implantation by the effect of elastic force toward extrapolated, and tightly penetrate and be fixed in alveolar bone, namely achieve its being closely firmly connected with human body alveolar bone.

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 plantation 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 made up of head, body and afterbody; Its implantation body 1 body is provided with the groove 7 of cross direction profiles, has spring 2 in groove 7, has jacking block 3 outside spring 2; This jacking block 3 is specially convex shape, and lateral ends is pointed bur; The body of its implantation body 1 is cylinder, and appearance is also 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; 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 are respectively provided with a 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; The afterbody of its implantation body 1 is smooth hemisphere face 12; 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 this plantation artificial tooth 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.
