Abstract

A number of pour-type denture base resins were found to have low glass transition temperatures, indicating a propensity to thermal distortion. These low transition temperatures reflected high residual monomer contents. Furthermore, such materials exhibited high mechanical loss tangents, consistent with high creep rates observed previously.

摘要

一些灌注型义齿基托树脂被发现具有较低的玻璃化转变温度，这表明它们有热变形的倾向。这些低转变温度反映出高残留单体含量。此外，这类材料表现出较高的力学损耗角正切，这与之前观察到的高蠕变速率一致。
