Grid-shaped anterior tooth preparation observation plate and digital preparation method thereof

Abstract

The invention discloses a grating-shaped anterior tooth preparation observation plate and a digital preparation method thereof, and belongs to the technical field of digital preparation. According to the method, the inner side face of the tooth preparation indicating plate serves as a reference face, the space formed by the reference face and the prepared preparation face is in uniform transition from the gingival margin to the incisal margin, the grating facilitates multi-point observation, the personalized thickness of the indicating plate can help doctors to better evaluate the tooth preparation amount, and the requirements of tooth preparation and restoration manufacturing can be met. According to the tooth preparation observation plate, the problem that the tooth grinding amount is not easy to judge in clinic can be solved to a certain extent, visual observation is carried out through the grating with the thickness being 1 mm or personalized thickness, and the tooth preparation amount can be accurately evaluated under the direct vision condition.

Description

technical field [0001] The invention belongs to the technical field of digital preparation, and particularly relates to a grid-shaped front tooth preparation observation board and a digital preparation method thereof. Background technique [0002] Porcelain veneers are a common method of aesthetic restoration of anterior teeth. After the diagnostic restoration is carried out using a wax-up, after the doctor and the patient confirm the restoration effect, the next step is tooth preparation. During the clinical operation, on the basis of meeting the space requirements for veneer preparation, we hope to retain the autologous tooth tissue as much as possible. How to use digital methods to quantify tooth preparation, preserve healthy tooth tissue as much as possible and reduce the incidence of pulp irritation is the goal of restorative doctors. [0003] The traditional method uses silicone rubber impressions to observe the amount of tooth preparation. In this way, only one obse...

Problems solved by technology

Therefore, using this type of preparation guide plate can only prepare the cylindrical surface, not the spherical surface, and the prepared surface after the preparation of the anterior teeth is not a cylindrical surface, but a uniformly transitioned curved surface

[0006] Therefore, the current digital preparation technology is still unable to meet the requirements of tooth preparation and restoration production, especially the ability to accurately observe and evaluate the amount of tooth preparation at any time
