Outline of Final Research Achievements

Biocompatibility of various dental and medical materials is affected by the 　conditions of materials surface, interface and erosion of trace metallic elements from the metallic materials and their accumulation in the tissues. In this study, the accumulation of dental alloy elements in the mucosa closely contacted with the metallic restorations using the position sensitive elemental and chemical state analysis method with X-ray microbeam. In addition, the chemical state analysis of the surface layer of surface treated titanium implant and the depth dependent change of titanium oxide was suggested.
