Dental restorations such as crowns, are made from lithium silicate glass ceramic that is heated and pressed onto a metal substrate, the latter being shaped to an impression or scan of the area of the mouth to receive the restoration. The metal substrate is made from an alloy selected to exhibit a coefficient of thermal expansion which is slightly greater than the CTE of the lithium silicate. In a preferred embodiment, the CTE of the lithium silicate glass ceramic is in the range of 11.5 to 12.5 and the alloy is selected to have a CTE of 12 to 13.5. A palladium tin alloy provides that CTE in the preferred embodiment.
