Abstract

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.

摘要

引言

本研究的目的是评估硅酮假体弹性体与聚甲基丙烯酸甲酯（PMMA）之间的界面粘结强度。

材料与方法

将硅酮弹性体附着于PMMA上，共制作120个样本，然后将其细分为12个亚组。接着对每个样本进行实验室测试以确定粘结强度。将粘结在不同表面丙烯酸上的硅酮弹性体样本放入万能试验机（HOUNSFIELD HT - 400）中进行“剥离试验”。记录所有获得的值并进行统计分析。

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）的粘结强度最高（平均值4.826±0.008 n/mm）。当仅使用底漆作为表面处理时，硅酮弹性体与丙烯酸树脂（DPI）的粘结强度为（4.351±0.0089）。而当硅酮粘结到用120目砂纸处理过的丙烯酸表面时，粘结强度值最低，对于DPI和TRAVELON分别为（0.076±0.00 n/mm）和（0.082±0.01 n/mm）。
