Abstract: A disposable dental impression tray for making impressions of edentulous dental arches with impressionable material is made of plastic or some other inexpensive material and includes a thin contoured plate having a contour approximating a section of an oral cavity of a mouth of which an impression is to be made. The plate has a impression side for holding impressionable material and an opposite backside. A reinforced edge runs around at least a portion or border of the plate and cross-bracing extends along the backside. A handle located at a front of the plate extends generally normal to and away from the backside of the plate and has a flat surface on a front and/or a back of the handle. Holes extend through the plate between the impression side and the backside and are located along the plate between cross-ribs of the bracing. The holes are flared outwardly from the impression side to the backside.
