Abstract
An improved dental impression tray provides an improved retentive force for the dental impression material contained therein by incorporating a plurality of projections and panels on its tray walls. Upon taking a dental impression, the dental impression material flows into the grooves defined by the plurality of projections, panels and the tray walls to form retentive components. These retentive components may prevent the impression material in the tray from distorting or being lifted out of the trays when the tray is disengaged from the oral anatomy of the patient.
