Patent

CA 2326279

A dental impression tray is provided with a wall member 14 which, in the working position of the tray, is disposed on the inner surface facing the jaw, is opposite the dental arch 21, 22 which faces the palate or tongue, respectively, and forms a flow surface 26 for directing the impression material 25 into the region between the tooth or stub 21, 22 and the gingiva 23. This prevents voids in the solidified impression; in the prior art such voids are produced due to the fact that the impression material 25 flows past cavities, pockets and/or undercuts 24 that exist in said region.
