ABSTRACT:
The dental impression tray for optional partially toothless jaw and toothless jaw with implants consists of a basic impression tray (1) and of a paired impression tray (2) freely arrangeable and positioned upon it, whereat the tray (1) is executed basically as a grooved horseshoe-shaped profile (3), whose side edges (4) are thickened with the purpose of strengthening, and the paired impression tray (2) is executed as a stiff horseshoe-shaped U-profile, which rests exactly on the outer thick edge (4) of the tray (1) so that between the trays (1) and (2) a space (6) is formed, which can accept a tooth with the impression material, and the thin-walled profile (3) of the tray (1) is foreseen for making holes (7) by handy dental tools at optional places in accordance with the state of the treated jaw.
