Abstract

The utility model relates to a dental implant. The dental implant comprises a top part, a body part and a root part, wherein the top part, the body part and the root part are connected along the longitudinal axial line direction, a first thread is formed on the surface of the outer wall of the body part, and a second thread is formed on the surface of the outer wall of the root part; at least one self-tapping slot is formed on the surface of the outer wall of the root part; each of the first thread and the second thread is formed by sheathing and connecting a large-pitch thread and a small-pitch thread; and the pitch of the first thread is smaller than that of the second thread, and the thread depth of the first thread is shallower than that of the second thread. The dental implant solves the problems of small combination area between the implant and the alveolar bone and damage to surrounding tissues are solved, and has the advantages of large combination area with the alveolar bone and good joint effect.

Description

A kind of tooth implant

Technical field

This utility model relates to the tooth-planting field, is specifically related to a kind of tooth implant.

Background technology

Penetrate the high compact bone of bone density with implantation body in the dentistry, heeling-in is in the lower spongy bone of bone density, but the bonded area of implantation body and alveolar bone is little usually, and a little less than the adhesion between the alveolar bone, cause the initial stage stationarity of implantation body to reduce, compact bone is not stimulated, can damage problems such as skeleton.

When firmware operation failure needs to give the big emergent implantation body of the urgent implanted diameter of patient, can produce usually and implant looseningly, destroy the problem of surrounding tissue, and can there be to the Compact bone injury problems such as big and primary stability is relatively poor in implantation body in implantation process.

The utility model content

The purpose of this utility model provides a kind of tooth implant that improves the conjugation of initial planting stability and implantation body and osseous tissue.

The technical scheme that realizes this utility model purpose is: a kind of tooth implant has top, body, root; Described top, body, root link to each other along longitudinal axis, and the outer wall surface of described body has first screw thread, and the outer wall surface of described root has second screw thread; The outer wall surface of described root also is provided with at least one self tapping groove.

Preferred described first screw thread and second screw thread all are socketed to form by steep-pitch thread and fine pitch screw thread; The pitch of described second screw thread of the pitch ratio of described first screw thread is little, and the depth of thread of described first screw thread is more shallow than the depth of thread of described second screw thread.

The diameter of section at preferred described top is greater than the diameter of section of described root, and described tooth implant is inverted cone; The end edge at described top is along the internal diameter contraction that slopes inwardly.

The utlity model has positive effect: second screw thread of (1) described root is darker, and pitch is bigger, can push spongy bone fully, and it is stable to help the increase initial stage; First screw thread of described body is more shallow, and pitch is less, can reduce the injury to Compact bone as far as possible, and it is stable to help the increase initial stage.

(2) closing in type ground in top designs, and helps the closure of gingiva; Described tooth implant is the design of inverted cone and self tapping groove can finish stable implantation by less rotation, avoids producing large torque and destroys perienchyma, improves the applying degree between firmware and the Compact bone, increases adhesion.

(2) described first screw thread and second screw thread all are socketed to form by steep-pitch thread and fine pitch screw thread, can increase contact area, improve associativity and fastness between tooth implant and the alveolar bone.

Description of drawings

Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, this utility model is described in further detail, wherein below

Fig. 1 is the structural representation of tooth implant;

The 1st, the top, the 2nd, body, the 3rd, root, 21 is first screw threads, 31 is second screw threads, the 4th, the self tapping groove

The specific embodiment

See Fig. 1, the utlity model has a kind of tooth implant, have top 1, body 2, root 3; Described top 1, body 2, root 3 link to each other along longitudinal axis, and the outer wall surface of described body 2 has first screw thread 21, and the outer wall surface of described root 3 has second screw thread 31; The outer wall surface of described root 3 also is provided with at least one self tapping groove 4.

Further described first screw thread 21 and second screw thread 31 all are socketed to form by steep-pitch thread and fine pitch screw thread; Contact area be can increase, associativity and fastness between tooth implant and the alveolar bone improved.

The pitch of described second screw thread 31 of the pitch ratio of described first screw thread 21 is little, and the depth of thread of described first screw thread 21 is more shallow than the depth of thread of described second screw thread 31; Second screw thread 31 of root is darker like this, and pitch is bigger, can push spongy bone fully, and it is stable to help the increase initial stage; First screw thread 21 of body is more shallow, and pitch is less, can reduce the injury to Compact bone as far as possible, and it is stable to help the increase initial stage.

The diameter of section at further described top 1 is greater than the diameter of section of described root 3, and described tooth implant is inverted cone; The end edge at described top 1 is along the internal diameter contraction that slopes inwardly; Closing in type ground, top designs, and helps the closure of gingiva.

Described tooth implant is the design of inverted cone and self tapping groove 4 can finish stable implantation by less rotation, avoids producing large torque and destroys perienchyma, improves the applying degree between firmware and the Compact bone, increases adhesion.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
