本研究检查了通过六个光固化单元聚合的八种假体复合材料的固化深度，以评估材料-固化单元组合的固化性能。每种复合材料均使用制造商推荐的光固化装置进行曝光。这些装置的光源为卤素灯/荧光灯、氙气灯、金属卤化物灯、荧光灯和卤素灯，曝光时间为20、30、60和90秒。材料的固化深度根据国际标准化组织（ISO 4049）描述的方法测定。通过方差分析（ANOVA）和多重比较区间对结果进行分析。双因素方差分析显示，固化深度同时受到材料单元组合和暴露时间的影响 (P = 0.0001)。在八种组合中，与金属卤化物固化单元（Hyper LII）聚合的混合复合材料（Prywood 颜色）在暴露 90 秒后表现出最大的固化深度。对于所有组合，较长时间的暴露会增加固化深度。
This study examined curing depth of eight prosthetic composite materials polymerized by means of six photo-curing units for the purpose of evaluating the curing performance of material-curing unit combinations. Each composite material was exposed with a photo-curing unit recommended by the manufacturer. The light sources of the units were halogen/fluorescent, xenon, metal halide, fluorescent, and halogen lamps, and exposure periods were 20, 30, 60, and 90 s. Curing depth of the materials was determined according to the method described by the International Organization for Standardization (ISO 4049). The results were analysed by factorial analysis of variance (ANOVA) and multiple comparison intervals. Two-factor ANOVA revealed that the depth of cure was influenced both by the material-unit combination and by the exposure period (P = 0.0001). Among the eight combinations, a hybrid composite material (Prywood color) polymerized with a metal halide curing unit (Hyper LII) exhibited the greatest depth of cure after 90-s exposure. For all combinations, longer exposure increased the depth of cure.
