Abstract

A dental impression tray used in cooperation with at least one impression material for obtaining an impression of a jaw, teeth and gingiva area in an oral cavity of a dentate or dental prosthesis patient and a method of use thereof. The dental impression tray comprises a body, a plurality of body openings, and a means of insertion and removal of the dental impression tray. The body is formed by an outer support section, a channel section and a central support section. The means for insertion and removal of the dental impression tray generally comprises a shelf section, a border and a handle section. The shelf section is attached to the body of the dental impression tray and serves to displace the pressure exerted upon the shelf section uniformly along the shelf section and onto the body. The border provides more surface area to improve retention of the impression material on the dental impression tray and to reduce the pressure against the jaw, teeth and gingiva areas. The plurality of body openings are positioned throughout the body to allow the impression material to vent through the body openings to obtain the impression and to retain the impression material onto the body.
