作者测试并比较了Empress陶瓷全冠着色上釉等热循环前后的边缘适合性.结果表明热压成形后的Empress 陶瓷冠其边缘浮升量为64.20μum(SD=9.49μm),着色上釉后的边缘浮升量为76.10μm(SD=10.85μm),两组间无显著性差异(P>O.05).提示该修复体具有良好的边缘浮升量,而成形后陶瓷冠再经历着色上釉等热过程有致使修复体轻微变形的倾向.
The authors tested and compared the edge suitability of the Empress ceramic crown before and after the thermal cycle such as glazed enamel.The results showed that the edge raised amount of the Empress ceramic crown was 64.20μum (SD = 9.49μm) The edge buoyancy was 76.10μm (SD = 10.85μm), with no significant difference between the two groups (P> 0.05), suggesting that this prosthesis had a good edge lift and the shaped ceramic crown underwent pigmentation Glaze and other thermal processes have caused the restoration of a slight tendency to deformation.
