A dental prosthesis comprising a metal alloy pre-form and a dental porcelain veneer coating the metal alloy, wherein the metal alloy has a composition comprising, in % by weight, about 30-40% Co, 25-40% Ru, 20-40% Cr, and 0-0.1 % Ni and wherein a coefficient of thermal expansion of the metal alloy is compatible with that of the dental porcelain to prevent cracking of the porcelain. The dental prosthesis can be manufactured through processes such as selective laser melting. |
