摘要
目前大块充填复合树脂逐渐应用于牙科治疗中,一些研究发现其除了具有操作简单的优势外,还具有良好的临床效果。单体转化率是反映树脂固化程度的重要指标,也是决定树脂的机械性能和生物学性能的重要因素。牙尖变形、边缘微渗漏是由于复合树脂的聚合收缩产生的收缩应力造成的,对充填体的耐久度、边缘封闭性有一定的影响,可以认为是衡量树脂粘接修复后的临床效果的常见指标。该文主要通过单体转化率、牙尖变形和边缘微渗漏这三方面对大块充填复合树脂修复后的临床效果以及原因机理做一个总结描述。
Bulk-fill composite resin is gradually applied to dental treatment now. Some studies have found that it not only has the advantage of convenient operation, but also has good clinical effect. As an important index of resin curing degree, the monomer conversion is an important factor that determines the mechanical and biological properties of composite resin. Cuspal deflection and marginal microleakage are caused by the polymerization shrinkage stress resulting from the shrinkage of composite resin, and it has certain influence on the durability of filling body and marginal sealing. It can be regarded as a common indicator of the clinical effect of composite resin. This paper mainly reviews the clinical effect and mechanism of bulk-fill composite resin through the monomer conversion, cuspal deflection and marginal microleakage.
