Method for generating tooth preparation track of robot-assisted tooth preparation function sharp slope

Abstract

The invention discloses a method for generating a tooth preparation track of a robot-assisted tooth preparation function sharp inclined plane, and relates to the technical field of robot-assisted tooth preparation. According to the invention, the method comprises the steps: planning a functional sharp inclined plane tooth preparation stage into three-dimensional curved surface track planning of the robot; based on a doctor standardized posterior tooth manual preparation body model, acquiring the curved surface data of the functional sharp inclined surface after preprocessing; dividing the functional sharp inclined surface into three curved surfaces according to the adjacent relationship and functions among teeth, and respectively obtaining the interpolation result of each curved surface; completing the tooth preparation trajectory planning of the three curved surfaces according to the molded value points of the curved surfaces and the characteristics of the curved surface patches, andestablishing the sharp bevel tooth preparation trajectory generation method for the robot-assisted tooth preparation function. According to the method, the curvature of the processed preparation bodymodel is smoother, the operation rate of the tooth preparation track is optimized, and the preparation precision of the tooth preparation curve is effectively improved.

Description

technical field

[0001] The patent of the present invention relates to a method for generating a tooth preparation track on a sharp inclined plane for robot-assisted tooth preparation, and belongs to the technical field of robot-assisted tooth preparation. Background technique

[0002] Dental caries is an important cause of tooth defects, seriously affecting people's oral health. Oral restoration is an important means of treating tooth defects. Tooth preparation is a necessary treatment link in the restoration process. It refers to the operation process in which the doctor quantitatively removes the teeth with caries and forms the expected three-dimensional shape. In the traditional tooth preparation process, it is necessary to rely on the manual operation of doctors combined with rich clinical experience to make a large number of repeated fine adjustments to carious teeth. However, the current situation of imbalanced doctor-patient ratio in my country cannot meet the curren...
