Embodiment 1

[0072] see Figure 2a , is a schematic structural diagram of an embodiment of an embedded guide plate for accurate root canal positioning according to the present invention. Specifically, the embedded guide plate in this embodiment includes a target tooth for complementing the residual crown / residual root state. The inlay 11 , and at least one guide hole 12 corresponding to at least one root canal in the target tooth, the guide hole 12 is located in the inlay 11 and penetrates the inlay 11 .

[0073] In this embodiment, the thickness of the inlay 11 is 2-4mm, and the diameter of the guide hole 12 is 0.5-0.8mm. In a specific embodiment, the diameter of the guide hole 12 is 0.6mm.

[0074] In this embodiment, since the target tooth is in the state of residual root / residual crown, when the inlay of the embedded guide plate for the precise positioning of the root canal is inserted into the target tooth, the target tooth is made complete, that is, the completed target The tooth is...

Abstract

The invention discloses a preparation method of an embedded guide plate for precise positioning of embedded root canals, which simulates the scene of precise matching of surgical instruments and target root canals in target teeth by constructing corresponding three-dimensional models, so as to obtain the preoperative Plan the path, and then obtain the relevant parameters of the embedded guide plate for precise positioning of the target root canal according to the preoperative planning path, and then prepare the embedded guide plate according to the relevant parameters, which can be used for the target of each residual root / crown state The personalized embedded guide plate for tooth preparation ensures the precise positioning of the target root canal in each target tooth, which significantly shortens the time for clinical root canal search (especially for variant root canals), and reduces the risk of side penetration and bottom canal Wear and other risks, improve the success rate of surgery, thus effectively retaining the affected teeth. Correspondingly, the present invention also provides a root canal precise positioning guide plate, its preparation system, application, and a root canal precise positioning method.

Description

technical field [0001] The invention relates to the technical field, relates to oral auxiliary medical devices, and in particular relates to an embedded guide plate for precise root canal positioning in root canal therapy and its preparation method, preparation system, application, and root canal precise positioning method. Background technique [0002] Endodontic disease and periapical disease are common and frequently-occurring diseases in oral clinical work. Currently, the most effective treatment method is root canal therapy. The principle of root canal therapy is to thoroughly clean, shape, and disinfect the complex root canal system of the tooth, and then use the filling material for strict root canal filling, thereby preventing the recurrence of infection. Successful root canal treatment requires a comprehensive understanding of the root canal system, without missing any root canal, thorough cleaning of the root canal, proper shaping, and tight three-dimensional filli...
