目的

用多个参数评价不同表面粗糙度及上釉方法对陶瓷上釉后表面光洁度的影响,为临床修复体的制作提供可参考的依据。

方法

制作盘状烤瓷试件100 个,随机分为5 组(A、B、C、D、E 组),每组各20 个,在注水条件下分别用碳化硅砂纸逐级打磨至220#、320#、600#、800#和1200#,各组再随机分为2 亚组,每亚组10 个,分别进行釉瓷上釉和自身上釉。 上釉前、后分别测量表面粗糙度参数轮廓算术平均偏差(Ra)、轮廓的最大高度(Rz)、轮廓单元的平均宽度(RSm)以及粗糙度的最大峰值(Rp),并用扫描电镜定性分析表面形貌。

结果

打磨至220# 的陶瓷上釉后表面Ra 最大[釉瓷上釉为(0.532 ± 0.109)μm、自身上釉(0.552 ±0.123)μm],打磨至1200#的陶瓷上釉后表面Ra最小[釉瓷上釉为(0.201 ± 0.050)μm、自身上釉(0.126 ± 0.016)μm],两种上釉方法都能获得光滑的上釉表面。

结论

上釉前的抛光处理以及不同上釉方法对上釉效果产生显著影响。

Objective

To explore the effect of different polishing and glazing techniques on the surface roughness of feldspathic ceramic via multiple evaluation parameters.

Methods

100 disc-shaped ceramic specimens (Vita VMK 95, 5.0 mm in diameter and 2.5 mm in thickness)were randomly divided into five groups (n=20), in which porcelain surfaces were ground sequentially with abrasive sandpapers to 220#, 320#, 600#, 800# and 1200# under water-cooling condition, respectively.Each group then divided into two subgroups (n=10) by means of glazing techniques, namely the overglazing group and the autoglazing group.The surface roughness parameters (including Ra, Rz, Rp and RSm) of the same specimen were measured by a profilometer both before and after glazing.And the surface characteristics of the representative specimen from each group were observed by scanning electron microscopy (SEM).

Results

The specimens ground 220# sandpapers displayed the highest Ra value after glazing,(0.532±0.109)μm in the overglazing group and (0.552±0.123)μm in the autoglazing group; while those sequentially polished to 1200# sandpapers obtained the lowest Ra value,(0.201±0.050)μm in the overglazing group and (0.126±0.016)μm in the autoglazing group.Both autoglazing and overglazing techniques could produce smooth ceramic surface.

Conclusion

Different polishing and glazing techniques have significant effects on the surface roughness of dental ceramic.
