This in vivo study assessed the clinical behaviour and early cavomarginal breakdown of a total of 42 "SR-Isosit" composite inlay restorations. Indirect examination of replica models by means of stereomicroscope and SEM-analysis indicated a stepwise loss of marginal adaptation within the six month period of clinical use. Microfractures were most frequently found in inlay margins located on functional cusp sites, while the resin luting agent still remained in place on etched enamel.
这项体内研究评估了总共42个“SR-Isosit”复合嵌体修复体的临床行为和早期洞缘破裂情况。通过体视显微镜和扫描电镜分析对复制模型进行间接检查,结果表明在临床使用的六个月期间,边缘适应性呈逐步丧失。微裂缝最常出现在位于功能尖部位的嵌体边缘,而树脂粘结剂仍保留在蚀刻牙釉质上。
