摘　　要：采用硼硅酸盐玻璃体系制备低熔钛专用体瓷,研究了体瓷组成与热膨胀系数的关系,并采用XRD和细胞毒性实验分别研究了钛体瓷的晶相组成和生物相容性。结果表明:钛体瓷为不含晶体的均质玻璃体,其热膨胀系数随SiO2含量的增加而减小;所研制的钛体瓷细胞毒性为0级,生物相容性良好,可望进一步应用于临床修复。The titanium dentin porcelain was synthesized through normal melting - derived route using bo- rate - silicate system. The porcelain was characterized by thermal expansion, X - ray diffraction and cyto- toxicity tests. The results of X - ray diffraction showed that the dentin porcelain is homogeneous vitreous and without erystalloids. The thermal expansion coefficient of dentin porcelains decreased with the in- creasing concentration of SiO2. The methyl thiazolyl tetrazolium assay results demonstrated that the cyto- toxicity of the titanium porcelain was ranked as 0. The titanium dentin porcelain synthesized in this re- search was a biocompatible material and could be used for dental implant materials.
