This invention deals with dental abstract restorations which are formed from glass-ceramic materials. In this invention the dental restorations may be formed by pressing. The resulting dental restorations have superior optical esthetic and strength properties. The invention includes dental restorations which are formed from particular lithium-disilicate glass-ceramics. In addition to forming dental restorations by pressing, the dental restorations may be milled. After forming the dental restorations are altered by applying one or more layers of a porcelain material to said dental restorations, and fusing said layers. |
