Description

Easy-to-install and anti-retreating implant

Technical Field

The utility model belongs to the field of tooth restoration, and particularly relates to an easy-to-install anti-back implant.

Background

At present, the implant has the advantages of better chewing function, good retention, beautiful appearance, comfort and convenience and the like compared with other false teeth, and is increasingly the first choice of a plurality of patients. However, a few kinds of implant still have some problems in the use process, such as loosening of the implant, and how to make the service life of the implant longer and keep the stability for long-term use is a always pursued direction of people. In addition, with the improvement of living standard, the comfort requirement of people on the tooth implantation process is also higher and higher. As shown in fig. 1, the fixed implant is divided into three parts: implant 1 (artificial root), abutment 2 (connector) and prosthetic crown 3. The implant 1 corresponds to a root, the abutment 2 corresponds to a trunk, and the repairing crown 3 is the branch and the leaf on the whole trunk. The implantation process of the implant is as follows: cutting gum of a patient, finding out alveolar bone and drilling holes, then placing an implant, fixing a temporary base on the implant, taking down the temporary base after the bone grows well after a few months, loading the temporary base into a permanent base, and loading a repairing crown to complete the whole planting process.

The existing implant of the implant and the permanent abutment are straight and cylindrical at the joint end part between the implant and the permanent abutment, in the growth of the previous months, the gum can fully or partially cover the temporary abutment, in the process of removing the temporary abutment and replacing the permanent abutment, as shown in figure 2, the gum needs to be broken aside or cut open, but because the gum still can be buckled inwards towards the middle in the process of planting, the problem that the flesh of the gum beside the fixed abutment is touched by threads or clamped between the threads to cause strong pain of patients often occurs in the process of fixing the permanent abutment, doctors often need to adjust to reduce the injury, thereby greatly reducing the efficiency of the screwing operation of the abutment and increasing the pain feeling of patients.

Disclosure of Invention

The utility model aims to provide the easy-to-mount and anti-back implant with high mounting efficiency, less pain and outstanding anti-back effect.

The utility model is realized by the following technical scheme:

the implant is easy to install and is prevented from retreating, and comprises an implant body 1, a base station 2 and a restoration crown 3, wherein the implant body 1 and the base station 2 are connected through a bolt arranged in the middle, the upper end 9 of the implant body 1 is of a frustum structure with a big top and a big bottom, the lower end of the base station 2 is of a frustum structure with a big top and a small bottom, and the frustum end face of the implant body 1 is matched with the frustum end face of the base station 2 in size; the outside of the implant 1 is provided with a fastening thread 4, a plurality of retaining grooves 5 are longitudinally dug on part of the fastening thread 4, a section of protruding part 6 is arranged on the bottom of the implant 1 corresponding to a lower hole part 10 with a large upper and a small lower taper left at the bottom of a hole when an alveolar bone is drilled, and a plurality of retaining rings 7 are longitudinally arranged on the protruding part 6.

Preferably, the retaining ring 7 is provided with a plurality of small holes 8 for enhancing the retaining effect.

Preferably, 2 rings 7 are provided on the extension portion 6 along the longitudinal direction.

The beneficial effects of the utility model are as follows:

the anti-back implant is ingenious in structure, the upper end part of the implant is of the frustum structure with the upper part being small and the lower part being large, the accommodating space of the gingiva positioned beside the implant can be increased as much as possible, the influence of the gingiva on the operation of the permanently fixed abutment is reduced, the pain of a patient is reduced, the operation speed is accelerated, meanwhile, bone can be better clamped into the groove by the arrangement of the anti-back groove, a better anti-back effect is brought, in addition, the anti-back effect can be further enhanced by arranging the extra anti-back ring which cannot be spirally twisted at the tapered bottom position of the drill hole of the alveolar bone, the stability of the implant is improved, the practicability is strong, and the anti-back implant is worth popularizing.
