摘要
用600C、700C、800C、900C4种铸模焙烧温度铸造Plat陶瓷冠40个,每组10个,测试并比较全冠各部位,各组全冠的适合性,结果表明各组间全冠的适合性无显著性差异,其边缘浮升量均为250μm左右。实验测得同一冠的龈缘及(牙合)面粘固剂厚度较接近,且远较轴壁处厚。
In this study the author investigated and compared the adaption of Plat castable ceramic crowns Which cast by varies model burnout temperature (600℃ . 700℃. 800 ℃ . 900℃ ). And the results indicated there were no significant differences of crown fit among fourgroups (P > 0. 05). The average marginal opening were 249. μm. 261μm. 267. 3μm. 265. 5μm tespectively, the cement thickness of occlusal and marginal parts were simila.and fairly more than that of axial parts.
