饰面瓷表面粗糙度对全瓷修复体颜色及透射率的影响
Effect of the veneer porcelain surface roughness on the transmittance and color of the two all-ceramic restorations
摘要
Abstract
Objective:To study the effect of different veneer porcelain surface roughness to the color and transmittance of the two all-ceramic restorations. Method: Make Cercon zirconia and IPS e.max into 20 discal specimens with 15 mm in diameter and 2.0 mm thick, each material is divided into four groups, each group specimens are burnished respectively to 400 #, 600 #, 800 #, 1000# with waterproof abrasive paper, measure the surface roughness Ra values and L*a*b*color parameters and transmittance. Result:The more waterproof abrasive paper mesh size is, the smaller the Ra value is. With veneer porce-lain surface roughnesses increasing, the L*values of Cercon zirconia increase and the b*values reduce, while the L*a*b*values of IPS e.max have no obvious change trend;translucency has up trend. Conclusion:Different veneer porcelain surface rough-nesses have some effect on the color and transmittance of Cercon zirconia and IPS e.max restorations.关键词
