DENTAL RESTORATION MATERIAL AND BIOMATERIAL FOR MEDICAL USE

摘要

PURPOSE: A dental restorative material and a medical bio-material are provided to improve binding force between surfaces of alloy and ceramic and to ensure high strength. CONSTITUTION: A dental restorative material is able to cover the metal surface with oxidation film formed by PEO(plasma electronic oxidation). The thickness of the oxidation film is 3-30 um. The dental restorative material additionally contains sintered ceramic coating layer. The thickness of the ceramic coating layer is 1-300 um. A medical bio-material is coated with an oxidation film formed by PEO.
