Denture feature modeling and processing by reverse engineering technology — A case study

The denture feature modeling and processing was studied by using the standard dental resin model with reverse engineering technology. After model scanning, data processing and surface fitting, a CAD model was created. Meanwhile, the teeth surface model of the permanent teeth crowns and the standard model of the entire column jaw teeth were established. According to the denture CAD model, the rapid prototyping parts of the column jaw teeth were completed. Then, the processing parts of the single-tooth and the entire column jaw teeth were obtained by the CNC programs, compiled for the dentures processing simulation. The results show that the actual dentures feasibility of CNC processing systems and the denture model are validated. This study lays solid foundation for the development of the low-cost, lightweight and fast denture CAD/CAM system.
