APPARATUS AND METHOD FOR PRODUCING A DENTAL PROSTHETIC

摘要

The present invention is directed to enhancing the accuracy with which tooth restorations (504) are machined, using a device (100) which can accurately copy mill a dental prosthetic blank from a previously formed dental prosthetic model, and which can closely replicate the feel of a dental tool to which dentists are accoustomed. The device includes a rotatable holding fixture (104) for holding the model to be copied and a second rotatable holding fixture (304) for holding the blank to be milled. The device further includes an upper beam assembly (204) for linear, rotary motion on a linear rotary axis for holding tracing stylus (118) and parallel tool cutting member in mount (202). A mill blank having an outer ceramic and inner resin of a lesser hardness so as to be milled is disclosed.
