Abstract:
1. A method for evaluating prosthetic dental item data representing a prosthetic dental item, the method comprising: acquiring prosthetic dental item data including surface data representing a three-dimensional surface of the prosthetic dental item; acquiring milling block data including volume data representing a three-dimensional volume of a corresponding milling block; determining whether one or more predetermined characteristics associated with the prosthetic dental item satisfy one or more predetermined acceptability criteria based on the prosthetic dental item data and the milling block data, wherein the one or more predetermined characteristics associated with the prosthetic dental item include a stress distribution of at least one tooth surrounding the prosthetic dental item, wherein the determining includes comparing the stress distribution to a nominal stress distribution, and the determining is performed at least in part by a computer processor; and based on a result of the comparing, generating positioning data representing a three-dimensional volume of the prosthetic dental item within the three-dimensional volume of the corresponding milling block.
