摘要：
The titanium opaque porcelain was synthesized through normal melting-derived route. The porcelain was characterized by thermal expansion, X-ray diffraction (XRD), and cytotoxicity tests. The results of XRD showed that the main phase of the opaque porcelain was SnO2. The Vickers hardness and flexure strength increased with increasing concentration of SnO2. The thermal expansion coefficient of opaque porcelains decreased with increasing concentration of SnO2 (or decreased with decreasing concentration of SiO2). The one-way ANOVA test indicated that there was no significant difference between the bonding strength of self-made titanium porcelain systems and super porcelain Ti-22. In this research, all measured bonding strengths were higher than 25MPa (ISO 9693 standard). The methyl thiazolyl tetrazolium assay results demonstrated that the cytotoxicity of the titanium opaque porcelain was ranked as zero.
