This study examined the effect of interchanging mixing tips on void formation for impressions of an automixed addition silicone material. The impressions were made of a series of stainless-steel cylinders by two dentists. The voids were counted at a predetermined site with a binocular microscope. The results showed that there were no significant variations in the number of voids in impressions of the automixed addition silicone using the three different mixing tips. However, one dentist made impressions that had substantially less voids for all three mixing tips.
本研究考察了更换混合头对自混合加成型硅橡胶材料印模中气泡形成的影响。两位牙医使用一系列不锈钢圆柱体制作印模。用双目显微镜在预定部位对气泡进行计数。结果显示，使用三种不同混合头制作的自混合加成型硅橡胶印模中的气泡数量没有显著差异。然而，一位牙医制作的印模在使用所有三种混合头时气泡都明显更少。
