Abstract
The present study has shown that there is no correlation between the free curing contraction of three selected addition-type silicone impression materials and the effective contraction determined as the accuracy of stone dies produced in dental impressions of these materials. Depending on specific rheologic properties, the free curing contraction of an impression material can be partly compensated for by flow.
摘要
本研究表明，三种选定的加成型硅橡胶印模材料的自由固化收缩与作为这些材料牙印模中制作的石膏模型精度所确定的有效收缩之间不存在相关性。根据特定的流变学特性，印模材料的自由固化收缩可部分通过流动得到补偿。
