目的：检测聚甲基丙烯酸甲酯(PMMA)树脂义齿表面二氧化钛涂层的临床外观(颜色、光泽度和表面粗糙度)。结果：L国际委员会的颜色系统显示了涂覆与不涂覆的样品之间的颜色变化。涂有二氧化钛的PMMA样本显示出很高的光泽度，突出了义齿的高效自洁作用。结论：较薄的二氧化钛涂层在保持义齿基托材料颜色的同时，具有较高的光泽度。(C)2015年日本口腔修复学会。由爱尔兰爱思唯尔出版。版权所有。
Purpose: We examined the clinical appearance (color, gloss, and surface roughness) of TiO2 coating on polymethyl methacrylate (PMMA) resin dentures.Methods: A spraying method, using air brushes, was used to generate thin uniform TiO2 coating. PMMA resin, primer-coated PMMA, and TiO2-coated PMMA (with primer) specimens were compared.Results: The Commission Internationale de l'Eclairage (CIE) color system revealed color variations between the with/without coated samples. The TiO2-coated PMMA specimen displayed high levels of glossiness, highlighting the efficient self-cleansing actions of the denture. The measured surface roughness decreased upon primer coating, and increased following TiO2 coating.Conclusions: The thin TiO2 coating afforded high levels of glossiness while maintaining the color of the denture base material.
