Abstract
A rack for holding dental impression trays includes a rectangular block having apertures therein to receive the handles or tubes extending from the trays and to cantilever the trays from the rack. A paired arrangement of apertures can accommodate a tray having both a handle and tubes. A base supporting the rack upright has wells therein for holding water which, together with a dome enclosing the rack, provide a moist atmosphere for the impression material, where needed. The rack can be free-standing or wall-mounted. One embodiment of the rack adapted for wall-mounting can be inexpensively manufactured of plastic by extrusion.
