The aim of this study was to examine the effect of various surface treatments on the bond strength of a resin luting agent and the surface roughness and surface energy of computer-aided design and computer-aided manufacturing (CAD/CAM) materials. Four types of CAD/CAM blocks (Shofu Block HC: BHC; GC Cerasmart: CER; VITA Enamic: ENA; and Lava Ultimate: LAV) were used. All blocks were randomly divided into eight groups based on the surface treatment as follows: no surface treatment (C), airborne-particle abrasion (AA), hydrofluoric acid etching (HA), silane coupling agent application (SL), AA/SL, HA/SL, AA/HA, and AA/HA/SL. The microtensile bond strength (µTBS), surface roughness and surface energy were measured. Three-way ANOVA revealed that all surface treatments significantly influenced the µTBS between the resin luting agent and all types of CAD/CAM materials; however, the effect of each surface treatment on surface roughness and energy was dependent on the CAD/CAM materials.
本研究旨在探讨不同表面处理对树脂水门汀与计算机辅助设计和计算机辅助制造（CAD/CAM）材料的粘结强度、表面粗糙度和表面能的影响。使用了四种 CAD/CAM 块（Shofu Block HC：BHC；GC Cerasmart：CER；VITA Enamic：ENA；和 Lava Ultimate：LAV）。所有块均根据表面处理随机分为以下 8 组：无表面处理（C）、喷丸处理（AA）、氢氟酸蚀刻（HA）、硅烷偶联剂处理（SL）、AA/SL、HA/SL、AA/HA 和 AA/HA/SL。测量微拉伸粘结强度（µTBS）、表面粗糙度和表面能。三因素方差分析显示，所有表面处理均显著影响树脂水门汀与所有类型 CAD/CAM 材料之间的 µTBS；然而，每种表面处理对表面粗糙度和能量的影响取决于 CAD/CAM 材料。
