Abstract: The titanium dentin porcelain was synthesized through normal melting-derived route using borate-silicate system.The porcelain was characterized by thermal expansion,X-ray diffraction and cytotoxicity tests.The results of X-ray diffraction showed that the dentin porcelain is homogeneous vitreous and without crystalloids.The thermal expansion coefficient of dentin porcelains decreased with the increasing concentration of SiO₂.The methyl thiazolyl tetrazolium assay results demonstrated that the cytotoxicity of the titanium porcelain was ranked as 0.The titanium dentin porcelain synthesized in this research was a biocompatible material and could be used for dental implant materials.
