介绍
本研究旨在评价硅胶假体弹性体与聚甲基丙烯酸甲酯（PMMA）之间的界面粘合强度。
材料和方法
将硅橡胶弹性体连接到PMMA上，共制造了120个样本，然后将其细分为12个亚组。然后对每个样品进行实验室测试以确定粘结强度。将不同表面的有机硅弹性体粘合到丙烯酸酯上的试样放入万能试验机（HOUNSFIELD HT-400）中进行“剥离试验”。将获得的所有值制成表格并进行统计分析。
结果
当仅使用底漆作为表面处理时，硅酮弹性体与丙烯酸树脂（TRAVELON）的粘合强度最高（平均值为4.826 ± 0.008 n/mm）。当仅使用底漆作为表面处理时，有机硅弹性体与丙烯酸树脂（DPI）的粘结强度为（4.351 ± 0.0089）。而经120目砂纸处理的有机硅与丙烯酸树脂的粘接强度最低，DPI和TRAVELON分别为（0.076 ± 0.00）n/mm和（0.082 ± 0.01）n/mm。
结论
在丙烯酸树脂表面使用底漆时，硅橡胶与丙烯酸树脂的粘结强度较高。与DPI树脂相比，Travelon树脂的硅橡胶与丙烯酸树脂的粘结强度更高。而有机硅与丙烯酸树脂表面砂纸粘合时，粘合强度较低。
INTRODUCTION
The aim of the study is to evaluate interfacial bond strength between silicone prosthetic elastomers and polymethylmethacrylate (PMMA).
MATERIALS AND METHODS
Silicone elastomers were attached to PMMA and a total 120 specimens were fabricated which were then subdivided into 12 sub-groups. Each sample was then subjected to laboratory test to determine the bond strength. The specimen of silicone elastomer bonded to acrylic of different surfaces was placed into universal testing machine (HOUNSFIELD HT-400) for "PEEL TEST". All the values obtained were tabulated and subjected to statistical analysis.
RESULT
The bond strength of silicone elastomer to acrylic resin (TRAVELON) noticed highest (Mean 4.826 ± 0.008 n/mm) when only primer was used as a surface treatment. When silicone elastomer bonded to acrylic resin (DPI) showed the bond strength of (4.351 ± 0.0089) when only primer was used as a surface treatment. Whereas the least bond strength values were found when the silicone bonded to acrylic surface treated by 120 grit sand paper that is (0.076 ± 0.00 n/mm) and (0.082 ± 0.01 n/mm) for DPI and TRAVELON respectively.
CONCLUSION
The bond strength of silicone elastomer to acrylic resin was higher when primer was used on the acrylic surface. The bond strength of silicone elastomer to acrylic resin was more with travelon resin when compared to DPI resin. But when silicone was bonded to acrylic surface with sand papering, showed less bond strength.
