本研究的目的是评估树脂复合嵌体系统在人体临床试验中的应用。在I类和II类预备体以及前磨牙和磨牙中平均插入60个修复体。在牙本质上涂上玻璃离子衬垫。在口腔环境中制备光固化直接嵌体。30个镶嵌体在125摄氏度的干热烘箱中热处理7.5分钟。用37%磷酸凝胶对制备的牙釉质边缘进行蚀刻。所有嵌体都用光固化的珐琅粘接树脂粘接。采用USPHS系统和M-L间接比例尺对修复进行评价。6个月、12个月、24个月和36个月的回顾与基线进行比较。所有修复体的颜色、界面染色、继发性龋齿和磨损与基线相比没有变化。边缘完整性和表面纹理表现出与基线和恢复类型不同的差异变化。间接磨损在修复体类型间差异无统计学意义（P < 0.05）。热处理组的耐磨性没有明显改善，但在24个月和36个月的召回中，热处理组的边缘完整性和表面特性有明显改善。
The purpose of this study was to evaluate a resin composite inlay system in clinical trials involving human subjects. A total of 60 restorations were inserted equally in Class I and II preparations and in premolars and molars. A glass ionomer liner was applied to the dentin. Light-cured direct inlays were fabricated in the oral environment. Thirty inlays were heat-treated for 7.5 minutes at 125 degrees C in a dry heat oven. Enamel margins of the preparations were etched with 37% phosphoric acid gel. All inlays were cemented with a light-cured enamel bonding resin. Restorations were evaluated using the USPHS system and M-L indirect scale. Six, 12, 24 and 36-month recalls were compared to baseline. Color, interfacial staining, secondary caries, and wear were unchanged from baseline for all restorations. Marginal integrity and surface texture show a differential change from baseline and with respect to restoration type. Indirect wear was not significantly different between restoration types (P < 0.05). Wear resistance was not significantly improved with heat treatment, but marginal integrity and surface characteristics showed marked improvement in the heat-treated group at 24 and 36-month recalls.
