[Abstract]:Tooth preparation is a key link in the treatment of dental hard tissue diseases. In order to develop a new model of tooth preparation and to automate the preparation of tooth preparation, the computer generation and parameterized modification of complex shape, multi-constrained tooth preparation model were studied. First, according to the size constraint characteristics of triangular mesh model, by analyzing the relationship between the model size chain, a parameterized operation for the generation of the preparatory body model is proposed, by which the preparatory body model within the standard range of all-ceramic restoration can be generated. At the same time, the parameterized dynamic modification of the preparatory volume model is realized by using the historical method. The parameterization experiments of 20 cases of premolar and 20 cases of premolar show that the algorithm can complete the model generation and parametric modification of the premolar model well. The third party software Geomagic Studio proves that the model design deviation is less than 48 渭 m and less than 100 渭 m. It has laid a solid foundation for reforming clinical operation mode and developing automatic dental preparation equipment.
