摘要
口腔印模的质量直接影响修复体的准确性和修复质量。临床常用的口腔弹性印模材料有藻酸盐水胶体印模材料、琼脂水胶体印模材料、硅橡胶印模材料、聚醚橡胶印模材料和聚硫橡胶印模材料。各种材料组成不同,性能各异,临床使用时应根据具体病例,选择合适的印模材料和消毒方法,以获取最佳效果。本文主要介绍了各弹性印模材料性能特点及临床使用注意事项。
The quality of impression plays a very impor-tant role in the accuracy and quality of the final restoratives.The commonly used elastic impression materials in clinic are alginate hydrocolloid impression material, agar hydrocolloid impression material, silicone impression material, polyether impression material and polysulfide impression material. Their properties are varies from each other due to the differences in compositions. Thus, in order to achieve the best treatment re-suits, it is important to select appropriate impression materials and disinfection methods according to the cases in clinic.
