title: Using copy milling technology in restorative dentistry.
abstract: A technique for the fabrication of copy milled ceramic restorations has been presented. Both direct and indirect fabrication techniques of inlays, onlays, veneers, and crowns are possible. A copy milling machine can mill accurately fitting restorations with a marginal gap of 50 microns. The machine uses premanufactured porcelain blanks, which have improved physical properties over conventional porcelains used in standard techniques. Recently, the ability to mill In-Ceram crowns from presintered alumina blocks and Spinell crowns from alumina/magnesia blocks has been added to the system. The copings are veneered with aluminous porcelain as in the conventional In-Ceram technique.
