Abstract
Improved dental stock trays capable of taking a precise impression without an individual tray are disclosed. The improved trays are made by newly adding several features to conventional stock trays. For a dentulous maxilla, the improved maxillary tray comprises the added features: a small through hole at the front and central position in a side wall, a projecting plate at the convex and central position in a base, projections at the rear edge positions in the base, and protuberances at the rear end positions in an outer surface of the side wall. The hole, plate, projections and protuberances are in the neighborhoods facing an incisive papilla (or a median frenum), a median palatine raphe (or a palatine foveola), a hamular notch and a maxillary tuberosity, respectively, when the tray is inserted in a mouth.
