摘要
目的研究氧化铝-氧化锆纳米复合渗透陶瓷底层冠的适合性。方法在1个标准代型基础上分别制备8个氧化铝-氧化锆纳米复合渗透陶瓷底层冠,黏结后测定底层冠适合性。结果氧化铝-氧化锆纳米复合渗透陶瓷底层冠表现出良好的适合性,平均绝对边缘间隙量65.84μm,在120μm的临床可接受范围内。结论氧化铝-氧化锆纳米复合渗透陶瓷底层冠具有良好的适合性。
Objective To evaluate the accuracy of adaptation on alumina-zirconia nano-composite infiltrated ceramic copings. Methods Alumina-zireonia nano-composite infiltrated ceramic copings were fabricated and their accuracy of adaptation were measured respectively. Results Alumina-zirconia nano-composite infiltrated ceramic copings exhibit high accuracy of adaptation： The mean absolute margin of the base copings is 65.84 tan, and in the receiving range of 120 tan in the clinic. Conclusion Copings fabricated with alumina-zirconia nano-composite infiltrated ceramic can obtain high accuracy of adaptation.
