大块充填树脂的研究进展

Research progress of bulk-fill resin-based composites

目前大块充填树脂已经越来越广泛应用于临床。一次4～6 mm的固化深度是大块充填树脂最突出的优点,便于临床操作。树脂的聚合收缩和边缘微渗漏及性能的长期稳定性与材料的临床应用效果密切相关。如何保证树脂具有较高的固化深度、较低的聚合收缩和边缘微渗漏以及临床效果评价是大块充填树脂的研究热点,该文将对上述几方面的研究进展进行综述。

Bulk-fill resin-based composite(bulk-fill RBCs)materials are increasingly being used for the clinical restoration nowadays. The outstanding advantage of bulk-fill RBCs is the capability to be placed and cured in 4-6mm increments one time,which is easy to operate. Resin polymerization shrinkage,marginal microleakage and long-term stability of properties are highly correlated with clinical effects. It is a hotspot in bulk-fill RBCs study to insure higher depth of cure,lower polymerization shrinkage and marginal microleakage,and clinical evaluation. This paper will review the advances on the above-mentioned aspects.
