Despite continuing improvements in resin-based composites,polymerization shrinkage remains a major drawback of polymerizable resins. Polymerization shrinkage generates stress within the composite that may lead to marginal gap formation,microleakage,postoperative sensitivity and secondary caries.
尽管树脂材料不断改进,仍然具有聚合收缩的缺陷,树脂聚合收缩常导致边缘微渗漏和裂隙的形成,这样就易于产生术后敏感和继发龋。
