Tooth positioning template, manufacturing method for same and components of tooth positioning template

Abstract

Disclosed are a tooth positioning template, a manufacturing method for the same and components of the tooth positioning template. The method includes that a tooth mold and a false tooth model are cut along a preset slice surface, and two marks are respectively fixed on two sides of the false tooth model on the preset slice surface; the marks, the false tooth model and the tooth mold surrounding the false tooth model are covered by shaping agent so as to form a positioning template; the positioning template is placed on teeth of the oral cavity of a user to realize computer tomography, and slice images of the preset slice surface are obtained; the slice images are proportionally attached on a cut surface of the tooth mold; an implanting body, implanting depth and implanting angle are selected according to the slice images attached on the tooth mold; and a positioning sleeve is mounted in the positioning template, and a drill is guided and started to drill a groove for the implanting body. By the aid of the tooth positioning template, the manufacturing method and the components of the tooth positioning template, a dentist can accurately estimate a tooth implanting surgery via the tomography images and the tooth model.

Description

technical field [0001] The invention relates to a tooth positioning template and its manufacturing method and components, in particular to a tooth positioning template for assisting positioning of implants and assisting in shooting tooth tomographic slice images, its manufacturing method and components. Background technique [0002] Generally, before dental implant surgery, a dentist will make a dental model based on the patient's teeth, and then determine the position of the implant, the angle and depth of the implant based on experience on the dental model. However, each patient's tooth structure is different, and the direction of tooth growth is also slightly different. If you only rely on personal experience without more reliable auxiliary tools, it may cause deviation of the implant position and damage the surrounding teeth or nerves. [0003] Therefore, dental implant surgery needs to be assisted by tomographic scanning in order to understand the patient's tooth struct...

AI Technical Summary

Problems solved by technology

[0005] However, the analysis of the implant position is in the computer environment, and it is difficult for the dentist to convert the implant position into the physical tooth model, and the implant position converted into the guide seat a2 may be biased

Furthermore, the cost threshold of 3D image analysis software and guide seat construction machines is too high, making it difficult to implement

More importantly, it cannot combine the appearance of the expected dentures and the images of the gums to evaluate the implants at the same time. It can only rely on the images of the gums to analyze the position and angle of the implants, which may cause inconsistencies between the implants and the adjacent teeth
