Auxiliary tool for intentional dental replantation

Abstract

The invention relates to an auxiliary tool for intentional dental replantation. The auxiliary tool comprises a fixing part capable of fixing teeth and a supporting part, wherein the fixing part is arranged in the supporting part in a sliding manner. The auxiliary tool is simple in structure and convenient to use; the teeth are stably fixed by adopting the fixing part, so that the auxiliary tool is prevented from being in direct contact with an area of a root of a bone boundary of enamel teeth; and meanwhile, the stability of cutting off roots of the teeth is ensured.

Description

Technical field [0001] The present invention is in the field of medical devices, particularly, to a secondary intention tooth replantation tooling. Background technique [0002] Intentionality replantation surgery is the treatment of a treatment with dental pulp periapical disease, mainly for root canal treatment failure and can not microscopic surgery apical teeth, the teeth of this kind is the ultimate means to save . The technique mainly refers to invasive teeth pulled from the tooth socket, removal of lesions in vitro root tip, the neurovascular apical root canal (root canal is a structure of internal teeth, tooth receiving, through teeth after the root canal therapy, neurovascular root canal is removed, the root canal with gutta percha filling enclosed) filling removing the original system biomaterial tight root canal filling, the final teeth then implanted back into the original alveolar nest; the technique can effectively preserve natural teeth to protect the oral health o...

AI Technical Summary

Problems solved by technology

During the actual operation, the crown of the tooth is mainly fixed by hand or pliers. However, it is still easy to touch the root area of ​​the enamel-cementum junction, and there is a risk of slippage when the tooth is fixed by hand or pliers

At the same time, when removing the original filling in the root canal (such as gutta-percha), the removed gutta-percha is easy to splash on the surface of the root because there is no cover. The time to remove these gums is time-consuming and laborious, and it also increases the risk of damaging the periodontal ligament cells on the root surface

At the same time, when cutting the root of the tooth, it is necessary to cut a certain length of the root. At present, it is mostly judged by the naked eye, and the accuracy of root cutting needs to be improved.
