摘要
目的 :初步研究了全瓷修复材料Plat铸造陶瓷材料的物理性能 ,为临床应用提供理论依据。方法 :采用经典的方法对Plat铸造陶瓷的密度 ,热膨胀系数 ,热传导率进行测定。结果 :Plat铸造陶瓷的密度为2.93g/cm3 ,热膨胀系数为9.87×10-6/℃ ,热传导率为0.0035卡/秒.cm.℃。结论 :Plat铸造陶瓷的密度 ,热膨胀系数 ,热传导率均与牙釉质相似 。
Objective: To study the physical properties of plat castable ceramic as a foundation of its clinical application. Methods:To test the density, coefficient of thermal expansion thermal conductivity of Plat castable ceramic with classical method. Results:The density of Plat castable ceramic is 2.93g/cm3 ,while 9.87×10-6/℃ for coefficient of thermal expansion, 0.0035 cal/s.cm.℃ for thermal conductivity. Conclusions: All above are similar to those of enamel and the other castable ceramics. The results indicated that Plat castable ceramic is a promising restoralive material
