牙科陶瓷调磨后不同的抛光上釉方法对其表面性状的影响

目的牙科陶瓷调磨后比较不同的抛光上釉方式其表面的光泽度。方法 用V intage瓷粉制作盘状试件24个,均匀调磨后按不同的处理方式随机分成四组,以粗糙度测试仪测量各组的粗糙度值并进行统计学分析,体视显微镜和电子显微镜观察试件表面形貌。结果抛光和上釉表面粗糙度值无显著性差异（P〉0.05）;镜下观察四组试件表面结构及光滑度无明显差别。结论牙科陶瓷调磨后抛光可以达到与自身上釉相近似的效果。

Effects of different polishing and glazing methods on the ceramic rough surface

Objective To compare the effects of different polishing and glazing methods on the ceramic rough surface.Methods Twenty-four ceramic samples were divided into four groups according to different polishing and glazing methods.Roughness of ceramic samples were measured and the data were analyzed.the surfaces microstructures were observed by the Stereoscopic Microscope and Scanning Electron Microscope(SEM).Results There were no significant differences in surface roughness values in polishing and glazing(P>0.05)...
