复合树脂在美观、机械性能、降低聚合收缩以及热膨胀系数等方面均优于无填料的树脂,与传统的铸造桩和核相比,复合材料还具有足够的强度并能缩短修复时间。因此复合树脂也能用于固定修复,例如对缺损严重的牙在作全冠修复前先用复合树脂修复牙体 Composite resins are superior to unfilled resins in terms of aesthetics, mechanical properties, reduced polymerization shrinkage, and coefficient of thermal expansion. The composites also have sufficient strength and can reduce repair time compared to traditional cast piles and cores. Therefore, the composite resin can also be used for fixed repair, for example, the defect of the tooth before making a full crown restoration with composite resin to repair the tooth
