Dental stake removal guide plate, system and design and manufacturing method of dental stake removal guide plate

Abstract

The invention relates to the technical field of medicine, and provides a dental stake removal guide plate, a system and a design and a manufacturing method of the dental stake removal guide plate. The dental stake removal guide plate comprises a supporting and fixing part and a restraining and guiding part, the supporting and fixing part is used for being arranged on a diseased tooth and an adjacent tooth, and the supporting and fixing part is provided with an exposure space for exposing the diseased tooth; the restraining and guiding part is arranged on the supporting and fixing part, a channel allowing the head of the dental handpiece to move is formed in the inner side of the restraining and guiding part, the channel is communicated with the exposure space, and a first opening allowing the neck of the dental handpiece to move is formed in the restraining and guiding part and is communicated with the channel. The restraining and guiding part arranged on the supporting and fixing part can serve as a guiding structure of the dental handpiece, so that a handpiece head of the dental handpiece stably moves in a channel of the restraining and guiding part, and a post core is ground to be removed.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a dental pile removal guide plate, a system and a design and manufacture method of the dental pile removal guide plate. Background technique [0002] In dental treatment, for teeth with large defects after root canal treatment, it is necessary to perform post-core restoration first, that is, the post-core is cemented in the root canal of the tooth to obtain retention and restore the shape of the defective part of the tooth; Perform full crown restoration. If pulp or periapical infection occurs in a tooth that has undergone post-core restoration, the post-core in the affected tooth needs to be removed before retreatment of the tooth can be performed. Since the post and core are cemented in the root canal of the tooth, the operation of removing the post and core is difficult and risky, and serious complications such as side penetration of the tooth are prone to irreparable seriou...

AI Technical Summary

Problems solved by technology

Since the post core is cemented in the root canal of the tooth, the operation of removing the post core is difficult and risky, and serious complications such as side penetration of the tooth are prone to irreparable serious complications, resulting in the extraction of the affected tooth

[0003] In related technologies, burs are also used to remove piles and cores, but the operation is more difficult, and problems such as deviation are prone to occur, which is not conducive to accurate grinding of piles and cores
