Abstract
Disclosed is a metal-metal oxide composite material for dental prosthesis, which has a white surface with good aesthetic quality and includes a titanium or titanium alloy substrate; and an oxidation layer present on a surface of the substrate. The metal-metal oxide composite material is manufactured by subjecting the substrate to a heat treatment at a temperature of around 1000° C. in an oxygen-containing atmosphere to form the oxidation layer on the surface of the substrate with good adhesion.
