Abstract

Knowing the properties and clinical indications of each material ensures that the dental surgeon can use techniques that guarantee better results for dental prostheses. This study aims to evaluate the dimensional stability of an irreversible hydrocolloid modified by the addition of silicone by condensation. During this evaluated the dimensional distortion of irreversible hydrocolloids according to conditioning time, for four commercial brands, being: Avagel (Dentsply), Hydrogum 5 (Zhermack Spa) and Jeltrate Plus (Dentsply) and Avagel plus Condensation Silicone (Zetaplus [Zhermach]). They were placed in a container with 100% humidity, and the following requirements were evaluated: weight, height, and length of the three groups during the following times: immediately, 24 hours, 48 hours, 72 hours, and 120 hours. All materials evaluated showed adequate dimensional stability within the initial 72 hours. The addition of condensation silicone to the irreversible hydrocolloid mixture did not improve the dimensional stability of the material.

缩聚硅改性不可逆水胶体的尺寸稳定性评价

了解每种材料的特性和临床适应症可以确保牙科医生可以使用技术来保证修复牙的更好效果。本研究旨在评价一种不可逆水胶体的尺寸稳定性，该水胶体是由硅酮的缩合改性而成的。在此过程中，根据调节时间评估了四个商业品牌不可逆水胶体的尺寸畸变，分别是:Avagel (Dentsply)、Hydrogum 5 (Zhermack Spa)、Jeltrate Plus (Dentsply)和Avagel Plus Condensation Silicone (Zetaplus [Zhermach])。将它们放置在100%湿度的容器中，评估以下要求:三组在以下时间内的体重、身高和长度:立即、24小时、48小时、72小时和120小时。所有评估的材料在最初的72小时内都显示出足够的尺寸稳定性。在不可逆水胶体混合物中加入缩合硅酮并没有提高材料的尺寸稳定性。
