本研究探讨了骨水泥膜厚度对口腔修复粘结剂拉伸粘结强度的影响。用Panavia Opaque粘合剂将Rexillium III合金圆柱体端对端粘合，并评价20、50、80、110、140和200 μm的膜厚度。将试样在5° C和60° C之间热循环24小时（1080次循环），在37° C下储存30天，并记录拉伸强度的平均粘合，包括失效模式。统计分析显示存在显著差异，但骨水泥膜厚度为80 μm时记录的粘结强度最强。
This study investigated the effect of cement film thickness on the tensile bond strength of a prosthodontic adhesive. Rexillium III alloy cylinders were bonded end-to-end with Panavia Opaque adhesive cement and film thicknesses of 20, 50, 80, 110, 140, and 200 μm were evaluated. The specimens were thermocycled for 24 hours (1080 cycles) between 5° and 60° C, stored for 30 days at 37° C, and the mean bonds for tensile strength, including the mode of failures, were recorded. Statistical analysis revealed significant differences, but the strongest bond strengths were recorded for the 80 μm cement film thickness.
