Positioning device for apical surgery and preparation method of positioning device

Abstract

The invention relates to the field of dental equipment, in particular to a positioning device for apical surgery and a preparation method of the positioning device. In order to reduce the risk of theapical surgery, improve the treatment quality and enable the long-term prognosis to develop well, the invention provides a positioning device for the apical surgery, which is characterized in that theperipheral side surface of a supporting plate is a convex arc surface; a positioning plate is located on the top face of the supporting plate and close to the peripheral side face of the supporting plate; a positioning through groove is formed in the positioning plate and is close to or located at the positioning end, away from the supporting plate, of the positioning plate; a positioning accessory is clamped in the positioning through groove; and a positioning guide through hole penetrating through the inner wall and the outer wall of the positioning accessory is formed in the positioning accessory. During use, the supporting plate is located between upper teeth and lower teeth of a patient, the positioning accessory is abutted against affected teeth, and the positioning guide through hole is located in the excision position of the root apex of the affected teeth. By using the positioning device for the apical surgery, the surgical risk can be reduced, the treatment quality can be improved, and long-term prognosis can be well developed.

Description

technical field [0001] The invention relates to the field of dental equipment, in particular to a positioning device for root tip surgery and a preparation method thereof. Background technique [0002] Root canal therapy is the treatment of choice for chronic periodontitis, however, when root canal therapy fails and is not suitable for root canal retreatment or root canal retreatment fails, or the affected tooth has severe root canal anatomical variation, or requires exploratory When the diagnosis is confirmed by surgery, it is often necessary to use the method of root apical surgery, that is, by scraping the periapical lesion tissue and resecting the infected root tip, dealing with the root tip stump, and using the mechanism of blood clots to deposit calcified substances to promote root healing. Surgical approaches to healing of periapical disease, including apicectomy, apical curettage, and apical backfilling. [0003] When using apical surgery to treat some periapical le...

AI Technical Summary

Problems solved by technology

Therefore, when using apical surgery to treat periapical lesions, it is necessary to accurately locate the resection length and angle of the apex of the affected tooth. However, at present, preoperative Cone beam CT (CBCT for short, ie cone CT) Preliminary understanding of the structure, direction, depth and periapical lesions of the root of the affected tooth, but the precise positioning of the resection length and angle of the root apex of the affected tooth, which leads to certain risks in the operation of the root apex, affects the quality of treatment and Good long-term prognosis
