摘要：
With the continuous improvement of the accuracy requirements of clinical base or base tooth and denture, the design of denture neck edge is becoming thinner and thinner, and the presintering zirconia dioxide billet for denture making evacuation and low strength material mechanical characteristics make the certain probability of denture neck edge fragmentation and peeling in the cutting process. Based on this phenomenon, the abnormal wear is the main reason, and a method of high frequency ultrasonic time cleaning to reduce the fracture of the denture neck in actual cutting is proposed.
