Abstract

A hydrophobic restorative composite based on a fluorocarbon analog of an alkyl methacrylate and a bisphenol adduct was formulated into a one-paste system, which polymerized in the presence of blue light. Physical, mechanical and water-related properties were determined. High contact angles and low water sorption were shown by the experimental composite. Capillary penetration of oral fluids around restorations, therefore, could be prevented in the presence of this highly hydrophobic surface. The physical and mechanical properties of the experimental composite were either comparable to or somewhat less favorable than commercial Bis-GMA composites.

摘要

一种基于甲基丙烯酸烷基酯的氟碳类似物和双酚加合物的疏水修复性复合材料被配制成单糊剂体系，该体系在蓝光存在下聚合。测定了其物理、机械和与水相关的性能。实验性复合材料表现出高接触角和低吸水率。因此，在这种高度疏水表面存在的情况下，可以防止修复体周围口腔液体的毛细管渗透。实验性复合材料的物理和机械性能与市售双酚A缩水甘油醚（Bis-GMA）复合材料相当，或略逊一筹。
