Abstract

The degree of polymerization of an acrylic resin repair material, as established by residual monomer estimation, was compared using three different polymerization methods, i.e. bench-cure, hydroflask-cure and microwave irradiation cure. The repair strength of a conventional heat-polymerized resin was then assessed following repairs using each of these three methods. The lowest level of residual monomer was achieved with the microwave irradiation cure. It was also demonstrated that of the three methods, polymerization using microwave energy resulted in the strongest repair.

摘要

通过残留单体估算确定了丙烯酸树脂修复材料的聚合度,使用三种不同的聚合方法进行比较,即台式固化、水浴烧瓶固化和微波辐射固化。然后评估了使用这三种方法中的每一种进行修复后传统热聚合树脂的修复强度。微波辐射固化实现了最低水平的残留单体。还证明了在这三种方法中,使用微波能量进行聚合产生的修复效果最强。
