摘要
目的观察聚合瓷嵌体和金属嵌体间接修复后牙邻面洞的疗效,为该技术的推广应用提供临床依据。方法采用随机双盲实验,实验组和对照组分别使用聚合瓷嵌体和金属嵌体,分别在修复后2年复诊,评价治疗效果。结果在年的追踪观察中,两组在修复体脱落、边缘折裂和继发龋发生情况上两组均表现出显著性差异。结论聚合瓷嵌体修复术用于邻面洞修复,既提高了充填后牙齿的整体强度,又降低了邻面洞对洞形预备的要求,可更大程度地保存牙体硬组织。
Objective To observe the effect of two kinds of inlay to the type U cavity of posterior teeth. Methods Two groups were divided randomly, one group with Ceramage inlay, the other with metal inlay. The restorations was examined after two years to evaluate clinical effects. Results At two years, statistical analysis showed significant differences between the two techniques in the retention of restorations. Restorations in Ceramage inlay were successful during this period in preventing marginal fracture and secondary caries ( P 〈 0. 05 ). Conclusion Ceramage inlay restorations were clinically successful in metal inlay over two years. It is concluded that Ceramage inlay indirect repair with tooth structure can partly restore the strength and rigidity lost by the cavity preparation. This may lead to a reduction in the incidence of tooth fracture due to fatigue.
