Drill point set for autologous tooth transplantation

Abstract

The invention relates to the technical field of dental medical instruments, in particular to a drill point set for autologous tooth transplantation, which comprises a pioneer drill, a ball drill and a split drill; the pioneer drill comprises a drill bit, a neck rod and a drill tail; the number of the pioneer drills is several; furthermore, the drill bit on each pioneer drill is of a circular truncated cone structure; the total length of each pioneer drill is 28 mm; the length of the drill bit is 16 mm; the diameter of the end, away from the neck rod, of the drill bit is 2 mm; the tapers of the drill bits are respectively 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8; a cutting knife is arranged at the end, away from the neck rod, of the drill bit; the number of the cutting knives is several; the cutting knives are evenly distributed at the end of the drill bit; and a part of the cutting knife is positioned on the circumference of the end part of the drill bit. The drill point set can be used for rapidly preparing a tooth socket matched with a supplied tooth, so that the operation time of autogenous tooth transplantation is shortened, the trial implantation times of the supplied tooth are reduced, and the success rate of autogenous tooth transplantation is improved.

Description

technical field [0001] The invention relates to the technical field of dental medical instruments, in particular to a drill set for autologous tooth implantation. Background technique [0002] Autologous tooth transplantation is currently an alternative clinical restoration method, and its advantage is that it not only extracts impacted teeth but also repairs dentition defects. The implanted teeth have good biocompatibility, can form periodontal ligament healing, preserve the height of the alveolar ridge, and the treatment period is short and economical. The success rate of autologous tooth transplantation is affected by many factors, including donor tooth condition, condition of implanted area, preparation of alveolar socket and external time of donor tooth. At present, high-speed turbines are used for the preparation of alveolar sockets. Due to their high speed, poor controllability, high cutting force and high heat generation, and repeated trial implantation and multiple...

AI Technical Summary

Problems solved by technology

At present, high-speed turbines are used for the preparation of alveolar sockets. Due to their high speed, poor controllability, high cutting force and high heat generation, and repeated trial implantation and multiple adjustments of implanted teeth are required to complete the preparation of alveolar sockets, which not only aggravates the Bone tissue damage increases the amount of bone removal, and also increases the operation time and the time for the donor tooth to be removed from the body, and the mismatch between the alveolar socket and the donor tooth reduces the initial stability, often leading to the failure of autologous tooth transplantation
