【摘要】：目的比较临床常用的几种玻璃陶瓷抛光工具对CEREC Blocs陶瓷的抛光效果,为临床抛光工具的选择提供依据。方法制作60个陶瓷试件,随机分为6组(n=10),进行不同的表面处理。G组:釉膏上釉;SF组:使用松风Porcelain Adjustment Kit+Cera Master组合抛光;3M组:使用3M Sof-LexTM Discs套装抛光;Tob组:使用道邦玻璃陶瓷套装抛光;EVE组:使用EVE DIAPRO套装抛光;Ivo组:使用义获嘉伟瓦登特Optra Fine?套装抛光。测量各组试件表面粗糙度值Ra、Rz并作统计分析,通过扫描电子显微镜(SEM)观测试件并对其表面形态作定性分析。结果 G、3M、SF、Ivo、EVE、Tob组的抛光后Ra值分别为(0.069±0.008)、(0.073±0.009)、(0.223±0.025)、(0.229±0.022)、(0.491±0.093)、(0.763±0.067)μm,经统计学分析,Ra值从小到大依次为G和3M组SF和Ivo组EVE组Tob组,其中G组与3M组、SF组与Ivo组的差异无统计学意义(P0.05),其余各组间差异均有统计学意义(P0.05)。Rz值统计结果与Ra值一致。SEM观察结果与粗糙度值的统计结果一致。结论不同抛光工具对CEREC Blocs陶瓷的抛光效果不同,本实验条件下,Sof-LexTM Discs套装抛光表面最光滑,效果近似釉膏上釉。
[Abstract]:Objective to compare the clinical effect of polishing several glass ceramic polishing tools for CEREC Blocs ceramics, provide the basis for clinical choice. The polishing tool making 60 ceramic specimens were randomly divided into 6 groups (n=10), surface treatment of different.G groups: the glaze paste glazed; group SF: the use of wind Porcelain Adjustment Kit+Cera Master 3M Sof-LexTM polishing; group 3M: Discs package using polishing; group Tob: daobang glass ceramic package use polishing; group EVE: EVE DIAPRO package using polishing; group Ivo: the use of justice Huojia Valerie Vaden Te Optra Fine? Set polishing. Measured specimen surface roughness values of Ra, Rz and statistical analysis. By scanning electron microscopy (SEM) observation of the specimens and makes a qualitative analysis on the surface morphology. The results of G, 3M, SF, Ivo, EVE, Tob group after polishing Ra = (0.069 + 0.008), (0.073 + 0.009), (0.223 + 0.025), (0.229 + 0.022), (0.491 + 0. 093), (0.763 + 0.067) m, by statistical analysis, the lowest Ra value were G and SF in 3M group and Ivo group EVE group Tob group, G group and 3M group, there was no significant difference between SF group and Ivo group (P0.05), other groups there were statistically significant differences (P0.05) the value of.Rz system in line with the values of Ra.SEM observation results and statistical roughness. Conclusion different polishing tool polishing effect on CEREC Blocs ceramics, under the experimental conditions, Sof-LexTM Discs set the most polished surface is smooth, the effect of glaze paste approximate glaze.
