ABSTRACT:
A dental impression tray has an outwardly extending flange that is connected to posterior portions of a trough or channel for receiving a quantity of impression materials. The flange permits the tray to be firmly gripped on the sides of the channel in areas adjacent opposite posterior regions of the patient's dental arch, so that the cured impression material may be disengaged from the arch without excessive permanent distortion of the impression. Preferably, the flange extends along the entire perimeter of the channel and adjacent an occlusal portion of the channel.
