陶瓷镶嵌体的磨损现象尚不完全清楚。本研究的目的是评估 8 年以上的陶瓷磨损、对抗牙釉质磨损和粘固水泥磨损。双重零假设是：(1) 陶瓷和搪瓷之间的磨损行为没有差异，(2) 粘合复合材料的填料含量对复合材料磨损没有影响。从 96 个修复体中，从 16 名参与者中选出了 36 个 II 级嵌体。对于具有相对牙釉质尖头的嵌体 (n = 17)，使用 3D 激光扫描仪扫描嵌体和牙釉质的复制品。使用轮廓仪分析嵌体的粘合间隙（n = 36），包括 3-D 数据分析。陶瓷和牙釉质磨损在 4 至 8 年间增加，6 年后牙釉质磨损值显着升高 (p < 0.05)。粘合间隙磨损持续增加长达 8 年 (p < 0.05)，而粘合复合材料 (p > 0.05) 和牙齿位置 (p > 0.05) 没有影响。
Wear phenomena of ceramic inlays are not fully understood. The aim of the present study was to evaluate ceramic wear, antagonist enamel wear, and luting cement wear over 8 years. The two-fold null hypothesis was that there would be ( 1) no difference in wear behavior between ceramic and enamel, and ( 2) no influence of filler content of luting composites on composite wear. From 96 restorations, 36 Class II inlays from 16 participants were selected. For inlays with opposing enamel cusps ( n = 17), replicas of inlays and enamel were scanned with a 3-D laser scanner. Luting gaps of inlays ( n = 36) were analyzed with a profilometer, including 3-D data analysis. Ceramic and enamel wear increased between 4 and 8 years, with significantly higher values for enamel after 6 years ( p < 0.05). Luting gap wear increased continuously up to 8 years ( p < 0.05), with no influence of luting composites ( p > 0.05) and location of teeth ( p > 0.05).
