Paper Title:
Effect of Surface Roughness on Matching Properties between Ceramic Framework and Coating-Glass for Dental Applications
  Abstract

This study was conducted to evaluate the influence of surface roughness on anchoring strength between ceramic and coating glass. Commercial Vita alpha glass-ceramic was selected as the coating glass, while the zirconia/alumina (Z/A) composite as the substrate. Anchoring strength between substrate and coating-glass was tested, and microstructure of the junction was also observed. From the experiments we can find the following results. There was significant difference in the mean strength of different surface roughness groups and HF acid-etching also had a favorable effect on matching properties. The highest amount of anchoring strength was occurred at the high scope of roughness after HF acid-etching and surface roughness will also affect the microstructure of the junction. Therefore, we can draw the conclusions that with the limit of this research, roughness will influence matching properties between ceramic substrate and coating-glass, while hydrofluoric acid etching was also suggested in the matching procedure. Testing matching properties between ceramic substrate and coating-glass should consider the influence of surface roughness.
