A computer-aided manufacturing system for dental restoration

In order to economize the labor time and increase the accuracy of dental restoration, an automated CAM system for NC tool path planning and generation is developed in this work. Compared with traditional methods, the proposed automated CAM system brings in a novel algorithm for model machining boundary extraction, an algorithm for multi-model path planning and an algorithm for tool path generation to economize labor time and increase the accuracy of denture. Based on the system, several different dental restorations, including single denture and multi-denture, from simple to complex, are planned and machined in experiments. Experimental results show that the system can highly improve the efficiency and the quality of denture during dental restorations. The work of this paper can bring the technology of automated denture repairing a big step forward. Its low price, high efficiency and simple operation will reduce the fee of dental restoration and enhance the quality and comfort at the same time.
