This study tested and compared properties of six modern indirect veneering resin composites (VRC), namely Ceramage (Shofu), dialog Vario (Schütz Dental), Gradia Plus (GC Europe), in:joy (Dentsply), Signum composite (Heraeus Kulzer), and SR Nexco (Ivoclar Vivadent). Specimens were fabricated from dentin and enamel pastes and following properties were analyzed: (1) two-body wear (TB), (2) surface roughness (SR), (3) Martens hardness parameters (HM and E), and (4) translucency (T). The highest impact on HM and E was exerted by VRC brand (HM: η=0.960/ E: η=0.968; p<0.001), followed by VRC paste material (HM: η=0.502/ E: η=0.580; p<0.001), and aging duration (HM: η=0.157/ E: η=0.112; p<0.001). Lowest and highest TB were measured for Signum composite and dialog Vario, respectively (p<0.001). Highest T was showed Signum composite and Ceramage (p<0.001). VRCs should be individually selected with respect to the indication area, due to different surface properties.
本研究测试和比较了六种现代间接贴面树脂复合材料（VRC）的性能，即 Ceramage（Shofu）、dialog Vario（Schütz Dental）、Gradia Plus（GC Europe）、in:joy（Dentsply）、Signum 复合材料（Heraeus Kulzer）和 SR Nexco（Ivoclar Vivadent）。从牙本质和牙釉质糊剂中制备试件，并分析以下性能：（1） 二体磨损（TB），（2）表面粗糙度（SR），（3）马氏硬度参数（HM 和 E）和（4）半透明度（T）。VRC 品牌对 HM 和 E 的影响最大（HM：η=0.960/ E：η=0.968；p<0.001），其次是 VRC 糊剂材料（HM：η=0.502/ E：η=0.580；p<0.001）和老化时间（HM：η=0.157/ E：η=0.112；p<0.001）。Signum 复合材料和 dialog Vario 的 TB 最低和最高（p<0.001）。Signum 复合材料和 Ceramage 的 T 值最高（p<0.001）。由于表面性能不同，VRC 应根据指示区域进行单独选择。
