This study examined voids produced in impressions of an automixed addition‐reaction silicone. Two operators took the impressions using material dispensed from either intra‐oral tips or an impression syringe. The material was also hand‐mixed for comparison. There were no differences in the number of voids in the automixed material dispensed using the intra‐oral tip or impression syringe. Automixing produced substantially fewer voids than hand‐mixing. There was a significant difference in the number of voids in the impressions made by the two operators.
