This study aimed to clarify how composition and water immersion of home reliners affect the attenuation of the transmitted load. To conduct a transmitted load measurement, we used three different home reliners (Tafugurippu Pink A, Liodent Pink, and Cushion Correct), which were combined acrylic resin disks. They were immersed in distilled water and then placed on a silicone quasi-mucosa (φ20×1.5 mm), which was set on a pressure sensor (φ8×0.35 mm), followed by the application of static load. Subsequently, gel permeation chromatography (GPC) and gas chromatography (GC) were used to clarify the composition of each home reliner. The attenuation of the transmitted load began 3 h after immersion. Moreover, both GPC and GC revealed a difference in composition among the three products. Further, the difference in the vinyl acetate molecular weight distribution and ethyl alcohol content affected the attenuation of the transmitted load of home reliners after water absorption.
本研究旨在阐明家庭用衬垫材料的成分和水浸情况如何影响传递负荷的衰减。为进行传递负荷测量，我们使用了三种不同的家庭用衬垫材料（Tafugurippu Pink A、Liodent Pink和Cushion Correct），它们是复合丙烯酸树脂圆盘。将它们浸入蒸馏水中，然后放置在置于压力传感器（φ8×0.35 mm）上的硅酮准黏膜（φ20×1.5 mm）上，随后施加静负荷。随后，使用凝胶渗透色谱法（GPC）和气相色谱法（GC）来阐明每种家庭用衬垫材料的成分。传递负荷的衰减在浸水3小时后开始。此外，GPC和GC均显示三种产品在成分上存在差异。此外，醋酸乙烯酯分子量分布和乙醇含量的差异影响了吸水后家庭用衬垫材料传递负荷的衰减。
