Abstract

The utility model provides a repairable single-piece dental implant. The dental implant is provided with an implant root part and an abutment, wherein, a thick threaded part capable of being screwed into the gums is arranged at the lower part of the implant root part, and a thin threaded part is formed at the upper part of the thick threaded part; the abutment is integrally connected above the thin threaded part of the implant root part and is used for mounting a dental crown; a through-hole is formed vertically downwards from the top surface of the abutment; the bottom of the through-hole extends to be close to the bottom end of the implant root part; when the abutment is broken, a post-and-core manufacturing technology can be conducted through the space formed by the through-hole; and a post nail is buried in the through-hole to repair the broken abutment.

Description

The repair type single-piece is planted the tooth body

Technical field

This utility model is planted the innovation structure design of tooth body (one piece implant) about a kind of single-piece, refers to that especially a kind of repair type single-piece plants the tooth body.

Background technology

Traditional dental implant surgical is to plant after tooth body (implant) imbeds in patient's dental bed one, and after planting above the tooth body with a screw combination stand (abutment), treating wound healing, assembling one corona on a stand is to finish dental implant surgical again.

Now existing a kind of single-piece is planted the design of tooth body (one piece implant), and it will prop up stand and plant the tooth body by integral forming, plants the implant surgery that the tooth body reaches a stand with convenient once promptly finishing.

In addition, present hat post and coronary disease (Post and core) manufacturing technology has been applied in the dental operation, generally damaging, rotting because of tooth structure or fracture is being directed at when not having the suitable assembling corona of enough tooth structures, utilize hat post and coronary disease manufacturing technology and can repair tooth structure, assemble in order to corona.But this hat post and coronary disease (Post and core) manufacturing technology still do not have and are applied to plant in the structure of taking root of tooth.

And single-piece plant the tooth body refill put corona after, under life-time service or improper use, propping up stand sometimes can rupture, and makes corona break away from dental bed, can not re-use.Must will remain in taking root in the dental bed and extract this moment, re-assembly; Under such situation, easier causing planted the tooth failure.This problem points remains to be improved in fact.

Summary of the invention

Edge this, the purpose of this utility model is to provide a kind of repair type single-piece to plant the tooth body, it can easily be preced with post when the fracture of stand and stand is propped up in the reparation of coronary disease manufacturing technology, plants tooth efficient thereby improve.

For achieving the above object, the utility model discloses a kind of repair type single-piece and plant the tooth body, comprising:

One portion that takes root, its below has a coarse-pitch thread portion that can shoot in the dental bed, and forms a fine thread portion above this coarse-pitch thread portion; And

A stand, one are connected in the fine thread portion top of this portion that takes root, and install a corona above this stand;

It is characterized in that; Offering one vertically downward from this stand end face utilizes its space to be preced with post and coronary disease manufacturing technology when fracture takes place for this stand and at the interior through hole that prop up stand reparation of a post nail rupture of imbedding, this via bottoms extends to the bottom near this portion that takes root.

Wherein, have a plurality of helical cuttings outside this coarse-pitch thread portion of portion that takes root, this helical cutting edge is formed with the cut edge of when implanting dental bed the bone tissue in this dental bed being cut and the bone tissue under the cutting is pushed in dental bed.

By said structure, this utility model is planted the through hole that tooth body inside is offered by monolithic, and utilizes hat post and coronary disease manufacturing technology, and can be with a stand reparation of fracture, and it is good planting tooth body result of use far beyond known single-piece.

Below, construction features of the present utility model will be described in detail according to the embodiment shown in the drawing and use effect.

The specific embodiment

See also Fig. 1 to shown in Figure 3, this utility model provides a kind of repair type single-piece to plant tooth body 10, it mainly has the portion of taking root 11, these portion 11 belows of taking root have a coarse-pitch thread portion 111 that can shoot in the dental bed 20, and above this coarse-pitch thread portion 111, form a fine thread portion 112, have a plurality of helical cuttings 113 outside the coarse-pitch thread portion 111, these helical cutting 113 edges form cut edge 113a.

Stand 12 one are connected in fine thread portion 112 tops of the portion of taking root 11, and its surface is provided with multiple tracks fin 121, and can be above it in order to install a corona 30, as shown in Figure 4.

Referring to Fig. 2 A, this utility model is main offers a through hole 13 vertically downward from stand 12 end face, and these through hole 13 bottoms extend to the bottom near the portion 11 that takes root.

In use, as shown in Figure 3, portion's 11 rotations of can will taking root are at a high speed shot in the dental bed 20, because helical cutting 113 edges form cut edge 113a can be with the cutting of the bone tissue in the dental bed 20, and the bone tissue under the cutting is pushed in dental bed 20, shown in arrow among the figure, raise operation as cooperating the nasal sinuses film, the bone tissue under the cutting is pushed in the nasal sinuses film space that is raised.Utilize the design of helical cutting 113, can simultaneously the bone meal that replenishes be filled in when implanting, the propelling movement of mat helical cutting 113 and filling are around the portion of taking root 11, to form stable structure.

After implanting wound healing, can be as shown in Figure 4, device one corona 30 is finished dental implant surgical outside a stand 12.

Referring to Fig. 5, life-time service or improper use corona 30 times, propping up stand 11 sometimes can rupture, and makes corona 30 disengaging dental beds 20.At this moment, as shown in Figure 6, can be preced with post and coronary disease (Post and core) manufacturing technology, in through hole 13, imbed a post nail 14 and repair with a stand 12 that will rupture in through hole 13 formed spaces.Again as shown in Figure 7, corona 30 is installed back on the stand 12, to finish reparation.

This utility model is planted the through hole 13 that tooth body 10 inside are offered by monolithic, and utilizes hat post and coronary disease (Post and core) manufacturing technology, and a stand 12 of fracture can be repaired, and it is good planting tooth body result of use far beyond known single-piece.

To sum up institute is old, and this utility model meets patent novelty and progressive important document fully, files an application in the whence in accordance with the law.
