The aim of this study was to evaluate the effects of post-curing by heat on the mechanical properties of visible-light (V-L) cured three inlay composites and three posterior filling composites. One group was only photo-cured according to the manufacturers' recommended methods, while the other group was heat-treated at 100 degrees C for 15 min following initial cure by V-L. Knoop hardness, diametral tensile strength and compressive strength were measured to evaluate the mechanical properties. Cure performance was checked out by the solvent immersion test. Upon secondary-curing by heat, it was confirmed that the mechanical properties of the composites were increased moderately and the cure performance of the composites was also improved.
本研究的目的是评估热后固化对三种可见光（V-L）固化嵌体复合材料和三种后牙充填复合材料力学性能的影响。一组仅按照制造商推荐的方法进行光固化，而另一组在V-L初始固化后于100℃热处理15分钟。测量努氏硬度、径向拉伸强度和抗压强度以评估力学性能。通过溶剂浸泡试验检查固化性能。经热二次固化后，证实复合材料的力学性能适度提高，且复合材料的固化性能也得到改善。
