Description
Technical field
This utility model relates to canine implant, particularly relates to a kind of combined type and plants tooth nail.
Background technology
For the patient of anodontia, Dental Implant preferably selects.Compared with traditional mode of having a denture made, Dental Implant has need not damage the advantages such as healthy adjacent teeth, and functionally, sensation, form is similar to natural teeth especially with in result of use, be even described as " the good teeth of the 3rd width of the mankind ".But because existing canine implant is mostly realize and its build-in by being encircled by the bone growth around installing hole after installation, such connected mode reliability is poor, constant species plants odontoseisis or the phenomenon such as to come off occurs, and is easy to cause the secondary injury to patient.In addition, the Dental Implant of existing design, mostly exist biocompatibility poor, implant after produces repel with tissue, the problem that service life is shorter, need further optimization.
Utility model content
The purpose of this utility model is to provide a kind of combined type to plant tooth nail, this combined type plant tooth nail can with human body alveolar bone compact siro spinning technology, have better biocompatibility concurrently.
The purpose of this utility model is achieved in that
Combined type plants a tooth nail, it is characterized in that: it is made up of implantation body, spring, slide block and ring-type porous tantalum product; Described implantation body is provided with the perforation of lateral direction penetrating; In the middle of described perforation, described spring is set; Described both ends of the spring is respectively arranged with described slide block; One end of described slide block is pointed bur; The body appearance of described implantation body is provided with ring-type rectangular recess, and is attached with one deck ring-type porous tantalum product in ring-type rectangular recess.
As further optimization, the afterbody of above-mentioned implantation body is bullet-headed.By this setting, its afterbody appearance gradient is larger and round and smooth, and the resistance be subject to during implantation is less, facilitates implant procedure; And its planform be approximately nail shape, implant after and body bone tissue embed closely, be connected firmly.
As further optimization, the head of above-mentioned implantation body is set to regular prism.Above-mentioned regular prism specifically can be set to regular triangular prism, four-prism or positive six prisms etc., is preferably set to positive six prisms.Install artificial tooth by corresponding on implantation body's head of regular prism shape, not only realize the implantation of artificial tooth, and prevent the rotation of artificial tooth, its connection is more reliable and more stable.
Above-mentioned slide block, concrete employing convex shape slide block, and slide block lateral ends is pointed bur.This slide block, also can be set to the object that other conventional one end such as cone are pointed bur.
Above-mentioned ring-type porous tantalum product, its porosity is 50% ~ 60%.Through adopting the ring-type porous tantalum product of this porosity, be attached in the ring-type rectangular recess of the body appearance of implantation body, to form composite structure, while meeting mechanical property requirements, osseous tissue also can be made to grow into this loose structure, and structure of growing in inwardly filling and then being formed, thus to achieve that artificial prosthesis and osseous tissue organically combine be one overall, substantially increase biocompatibility, also improve service life and implant comfort level, adding the stability after artificial prosthesis implantation and anti-rotation performance.This ring-type porous tantalum product can specifically adopt the preparations such as foam dipping method, die pressing.
This utility model has following beneficial effect:
1, its agent structure designs for integral type, and structure simplifies excellent;
2, by arranging the slide block that spring and one end are pointed bur in perforation, gone out by pointed bur one end thruster outward of the effect of elastic force by slide block after achieving implantation, and be tightly fixed in alveolar bone, and then achieve with the compact siro spinning technology of human body alveolar bone, combine firm;
3, the afterbody of its implantation body is designed to bullet-headed, and its appearance gradient is larger and round and smooth, and the resistance be subject to during implantation is less, facilitates implant procedure; And its planform be approximately nail shape, implant after and body bone tissue embed closely, be connected firmly;
4, install artificial tooth by corresponding on implantation body's head of regular prism shape, not only realize the implantation of artificial tooth, and prevent the rotation of artificial tooth, its connection is more reliable and more stable;
5, pass through at implantation body's body appearance ring-type rectangular recess, and in groove, adhere to ring-type porous tantalum product, achieve body bone tissue after implanting grow into be formed in this loose structure in grow into structure, considerably increase the stability after the biocompatibility of structure entirety, implantation and anti-rotation performance, improve service life and implant comfort level.

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 combined type plants tooth nail, and it is made up of implantation body 1, spring 2, slide block 3 and ring-type porous tantalum product 8; Its implantation body 1 is provided with the perforation 4 of lateral direction penetrating, arranges spring 2 in the middle of this perforation 4; These spring 2 two ends are respectively arranged with slide block 3, and this slide block 3 specifically adopts convex shape, and slide block lateral ends is pointed bur; The body appearance of its implantation body 1 is provided with ring-type rectangular recess 5, and in ring-type rectangular recess 5, being attached with the ring-type porous tantalum product 8 that a layer porosity is 50% ~ 55%, this ring-type porous tantalum product 8 specifically can with reference to employing method preparation as described in patent 201110296515.7; The afterbody 6 of its implantation body 1 is bullet-headed, and the head 7 of implantation body 1 is set to positive six prisms, installs artificial tooth, and then realize the implantation of artificial tooth in order to correspondence.
When clinical practice is implanted, first can get out an installing hole on alveolar bone, then this combined type be planted the implantation of tooth nail; Implant the slide block 3 at rear spring 2 two ends and stretch out perforation 4 under elastic force effect, the pointed bur of its lateral ends tightly penetrates in alveolar bone, and then achieves the compact siro spinning technology of it and human body alveolar bone; This structure can regulate in conjunction with firmness according to spring rate, convenient and reliable.In addition, be attached in the ring-type rectangular recess 5 of the body appearance of implantation body 1 by adopting ring-type porous tantalum product 8, define composite structure, while meeting mechanical property requirements, osseous tissue also can be made to grow into this loose structure, and structure of growing in inwardly filling and then being formed, thus to achieve that artificial prosthesis and osseous tissue organically combine be one overall, substantially increase biocompatibility, also improve service life and implant comfort level, adding the stability after artificial prosthesis implantation and anti-rotation performance.
