The aim of this study was to evaluate the interfacial bond strength between different types of silicone facial elastomers and denture resins.
The facial materials studied were Cosmesil and Ideal, whereas SR 3/60, SR 3/60 Quick, and Triad were included in the denture resins group. The "overlap-joint" model was used to evaluate the bond strength, and the samples were placed in tension until failure. The bonding surfaces were treated with a primer. Ten samples for each silicone/resin group were tested. The results were subjected to two-way analysis of variance and Tukey's test for comparison.
The bond strength was affected by the type of silicone elastomer and denture resin. An interaction between them was also noted. The bond strength ranged from 0.03 to 0.23 MPa.
Cosmesil condensation-type silicone always showed higher bond strength with the three different types of denture resins compared to Ideal addition silicone, keeping other variables associated with the silicone-resin bond fixed.
本研究旨在评估不同类型的硅酮面部弹性体与义齿树脂之间的界面粘结强度。
所研究的面部材料为Cosmesil和Ideal，而义齿树脂组包括SR 3/60、SR 3/60 Quick和Triad。采用“重叠接头”模型评估粘结强度，并将样品置于拉伸状态直至破坏。粘结表面用底漆处理。对每个硅酮/树脂组的10个样品进行测试。结果进行双向方差分析和Tukey检验以进行比较。
粘结强度受硅酮弹性体和义齿树脂类型的影响。还注意到它们之间的相互作用。粘结强度范围为0.03至0.23MPa。
在保持与硅酮 - 树脂粘结相关的其他变量不变的情况下，与Ideal加成型硅酮相比，Cosmesil缩合型硅酮与三种不同类型的义齿树脂始终表现出更高的粘结强度。
