Application of Three-dimensional Interactive Model in Education of Classification on Tooth Cavity

The purpose of the project is to develop the three-dimensional interactive model of G.V. Black‘s classifications of tooth cavity on the basis of 3D software and results of preliminary investigation on user requirement, and put it into the teaching of endodontic experiment class. The files of 3D-based interactive models for teaching and test have been made, and have several major functions, such as 3D browsing, annotation co mmunication. The application of 3D technique in experiment class of stomatology has the advantages of explicitness, clear-explained, strong, none-attrition, invested once for long-term use, and we can expand the breadth and depth of it in the future.
