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

The invention relates to the technical field of medicine, and proposes a dental pile removal guide plate, a system and a design and manufacture method of the dental pile removal guide plate. The dental pile removal guide plate includes a support and fixation part and a constraint guide part, the support and fixation part is used to be arranged on the affected tooth and its adjacent teeth, and the support and fixation part is provided with an exposure space for exposing the affected tooth; the constraint guide part is arranged on the support and fixation part On the inner side of the constraining guide part, there is a channel for the head of the dental handpiece to move, and the channel communicates with the exposed space. A first opening for the neck of the dental handpiece to move is formed on the constraining guide part, and the first opening is connected to the channel. connected. The constraining guiding part arranged on the supporting and fixing part can be used as a guiding structure of the dental handpiece, so that the handpiece of the dental handpiece can move stably in the channel of the constraining guiding part, thereby grinding away the post and core.
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...
