Abstract

OBJECTIVE

Since there is no material in the market met all the ideal requirements of an impression material, thus in an attempt to find one, hybridization between the two most commonly used impression materials were done. The aim of the hybridization was to obtain a new material combining the good merits of both and eliminate their shortcomings. Thus, this study aimed to assess the impact of hybridization between polyether with addition silicone on tear strength and elastic recovery of the new material and compare such effect with regard to parent materials.

RESULTS

A polyether (PE), polyvinyl siloxanse (PVS) and vinyl polyether silicone (VPES) hybrid elastomers were used in the present study. Tear strength was measured one hour after setting time of each material according to the manufacturer and the three materials showed statistically comparable tear strength in N/mm. Elastic recovery was evaluated one minute after the setting time recommended by the manufacturer. The three materials were statistically insignificant from each other, and all met the ISO4823 requirement of having greater than 96.5% recovery.

摘要

目的

由于市场上没有一种材料能完全满足印模材料的理想要求，因此试图寻找一种材料，将两种最常用的印模材料进行杂交。杂交的目的是获得一种新材料，结合两者的优点，消除其缺点。因此，本研究旨在评估聚醚与添加硅酮杂交对新材料撕裂强度和弹性回复的影响，并比较与母体材料的关系。

结果

本研究使用了聚醚（PE）、聚硅氧烷（PVS）和乙烯基聚醚硅氧烷（VPES）杂化弹性体。根据制造商的要求，在每种材料的凝固时间后一小时测量撕裂强度，三种材料的撕裂强度在 N/mm 上具有统计学可比性。弹性回复在制造商推荐的凝固时间一分钟后进行评估。三种材料彼此之间没有统计学差异，均符合 ISO4823 要求，回复率大于 96.5%。
