Bulk-fill composite resin are simple to operate, and they reduce polymerization shrinkage and microleakage compare to traditional resin-based composites. However, their clinical application could be affected by numerous factors, such as the material itself, light curing, placement techniques, storage condition, and preheating. This review aimed to summarize the definitions, classifications, indications, clinical properties, and influencing factors of the clinical application of bulk-fill resin-based composites and discuss the ways to improve their clinical effectiveness.
大块充填树脂与传统复合树脂相比有操作简单，低聚合收缩，微渗漏减少等优势。但在临床应用中受很多因素影响，如材料本身性能、光照因素、充填方法、储存条件、热处理等。本文将就大块充填树脂的定义及分类、临床应用适应证、性能、临床应用影响因素等方面进行阐述和讨论，为大块充填树脂的临床应用提供参考。.
