Pre-impression rinses help clean and prepare the impression site to help clinicians capture the most accurate dental impressions possible. These materials are applied or sprayed directly onto the prepared area prior to placing the impression tray in the patient's mouth. The rinses are designed to clean and decontaminate the impression site which provides a smooth impression for greater accuracy. Adding a pre-impression rinse to your impression protocol can improve the quality of the impressions captured in your operatories.
