Abstract
Porcelain compositions suitable for layers on metal base dental restorations have fusion temperatures of about 800.degree. C. and lower. The compositions may be employed as coatings on titanium and titanium alloy bases since the compositions have thermal expansion values close to those of titanium and its alloys. A bond layer is also provided to improve bonding between the porcelain layers and the restoration base. A method is also provided for forming dental restorations with relatively inexpensive and biocompatible metal bases and low fusing dental porcelains.
