Abstract

The utility model discloses a reverse dental implant, which comprises an implant body, wherein reverse threads are arranged on the implant body, and the reverse threads reversely rotate from the middle position of the implant body to the bottom position of the implant body; the utility model has the advantages of reasonable design, simple structure, through reverse threaded design, can twist produced bone meal with the planting body and bring into the bone lower floor and fill when the planting body twists in the bone, need not to use artifical bone meal to fill, consequently there is not rejection, also can reduce the probability that the planting body installation back lower floor's sinus membrane infects simultaneously, is favorable to the installation of planting body.

Description

Reverse dental implant

Technical Field

The utility model belongs to the technical field of medical science and technology of oral cavity and specifically relates to a reverse dental implant.

Background

Traditional planting body, its surface adopts clockwise screw usually to make the planting body produce bone meal along with clockwise screw outwards discharge when twisting in the bone, twist the back at the planting body, need use artificial bone meal to fill the planting body lower extreme, and artificial bone meal is as the filler, can appear repelling the phenomenon occasionally, and the use of artificial bone meal also very easily causes the infection of bone lower floor's sinus membrane, is unfavorable for the installation of planting body.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of proposing, provide a reverse dental implant for this, including the implant body, be provided with reverse screw on the implant body, reverse screw extends to the bottom position department of implant body from the reverse rotation of the intermediate position department of implant body, the structure of grow gradually is set to reverse screw thread interval from top to bottom.

The utility model has the advantages that: the utility model has the advantages of reasonable design, simple structure, through reverse threaded design, can twist produced bone meal with the planting body and bring into the bone lower floor and fill when the planting body twists in the bone, need not to use artifical bone meal to fill, consequently there is not rejection, also can reduce the probability that the planting body installation back lower floor's sinus membrane infects simultaneously, is favorable to the installation of planting body.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the structure of the implant of the present invention;

in the figure: 1. an implant body; 2. reverse threads; 3. a dental bone; 4. the sinus membrane.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The reverse dental implant comprises an implant body 1, wherein a reverse thread 2 is arranged on the implant body 1, the reverse thread 2 reversely rotates from the middle position of the implant body 1 to the bottom position of the implant body 1, and the thread space between the reverse thread 2 from top to bottom is set to be a gradually enlarged structure.

In the use process, the reverse thread 2 is arranged to enable bone powder generated when the implant body 1 is screwed in the dental bone 3 to be screwed in the bottom of the dental bone 3 along the reverse thread 2 when the implant body 1 is screwed in the dental bone 3, so that a gap between the dental bone 3 and the sinus membrane 4 is filled; reverse screw thread 2 from top to bottom sets up the structure that gradually the grow to can be convenient for the bone meal more smoothly enter into the clearance between tooth bone 3 and sinus membrane 4 along reverse screw thread 2.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.

Claims

1.
