ABSTRACT:
A dental impression tray particularly for the lower jaw which is designed with arcuate outer walls for the buccal side of the dental arch to locate the arch and has inner lingual walls angled to encircle and avoid contact with any tori growths within the dental arch, thus allowing the tray filled with soft and hardenable material to seat well within the dental arch to obtain a full tooth impression down to and below the gum line.
