Abstract:
A dental article is fabricated from an SMC material using three-dimensional data captured from natural dentition to guide a computer-controlled milling machine. The three-dimensional data may include scans of an original tooth structure and a prepared tooth surface to characterize all surfaces of a dental article, or certain features may be created within a computer-assisted design environment taking account of occlusion, proximal contacts, and the like. In addition the model applied to a computer-controlled milling machine may account for shrinkage of the SMC material during any post-milling curing steps in order to ensure an accurate fit to the prepared tooth surface.
