Description

Drill Sets for Autologous Tooth Implantation

technical field

The invention relates to the technical field of dental medical instruments, in particular to a drill set for autologous tooth implantation.

Background technique

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 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, which often leads to the failure of autologous tooth transplantation. Therefore, a special drill is needed to shorten the preparation time of the alveolar socket, reduce the number of donor tooth trial implants, and prepare an alveolar socket that matches the donor tooth, thereby improving the success rate of autologous tooth transplantation. In addition, when a tooth with a fully developed root is transplanted, the pulp often becomes necrotic. The necrotic pulp will cause bacterial action, which requires postoperative root canal treatment or intraoperative root canal removal and filling. If the root cutting and filling are carried out during the operation, it is simple and easy, saving time and effort. Since the apex after root cutting and backfilling is platform-shaped, the alveolar socket that needs to be prepared is roughly truncated. However, due to the large differences in the shape of the roots, the taper, length and maximum diameter of the alveolar sockets that need to be prepared are all different. Therefore, a series of drill sets are required to be used together to complete the preparation of the alveolar sockets.

In order to solve the above problems, the present invention provides a drill set for autologous tooth implantation.

2. Take CBCT before autologous tooth transplantation, select the pioneer drill that is closest to the root shape of the donor tooth according to the root length, root diameter and taper, use the drill with the smallest taper to the selected final drill, and then combine the ball drill and The intensive repair of the split drill can prepare the most suitable alveolar socket for the donor tooth with the minimum amount of grinding, which not only preserves the alveolar bone, but also makes the implanted teeth have initial stability and improves the success rate of implanted teeth;

3. If the donor tooth has double or triple roots, you can choose appropriate drills and prepare two or three frustum-shaped cones in different directions according to the direction of the root, so as to ensure that the root of the donor tooth can just accommodate the tooth root, which is very good Root spacing is preserved;

The object of the present invention is to provide a drill needle set for autologous tooth transplantation, through which the drill needle set can prepare the alveolar socket matching the donor tooth in the shortest time with the minimum amount of grinding, and improve the alveolar socket The efficiency of the preparation shortens the operation time, reduces the damage to the periodontal ligament of the donor tooth, preserves the alveolar bone as much as possible, increases the initial stability of the transplanted tooth, and can significantly improve the success rate of the transplanted tooth.
