ABSTRACT:
A dental impression tray contoured to fit over at least a portion of a patient's dentition is provided. The dental impression tray includes a wall portion and an elongate rib adapted to extend along the wall portion. The elongate rib and wall define a channel sufficiently elongate with respect to the portion of the patient's dentition to interfit with an impression material during an impression of the portion of the patient's dentition to hold the impression material more securely in the tray.
