Once the impressions are made, the clinician will record the type of impression material used; whether tray adhesive was used; the tray material; the type of tray used; and the number of units requested. The impressions will be photographed and digitally scanned and then collectively evaluated at a later time, based on a criteria evaluation form by two calibrated evaluators. The evaluator will assess each impression for errors in the finish line; in the tray/material; and errors with gingival displacement/hemostasis as primary outcomes. The number of errors can range from 0 to 13.
