METHOD FOR MAKING BASEPLATE TRAY Russian patent published in 2014 - IPC A61C9/00 

FIELD: medicine.

SUBSTANCE: stock tray is used to contour a jaw anatomical pattern. That is followed by making a stone cast after the contoured pattern. Expected trays borders are marked on the stone cast. A recess is created on the contoured pattern where a handle of the baseplate tray is supposed to be. A wax plate 0.5-1 mm thick is crimped on the stone cast over the whole surface along the borders of the expected baseplate tray. That is followed by placing thermal mass vertical bars 2 mm high on an alveolar crest within canines and first molars. Quick-setting plastic paste is further prepared. The above paste is applied on the stock tray with the anatomical pattern, and the stock tray with the pattern and plastic paste are pressed against the stone cast with wax. Herewith, 10-12 minutes are left until the quick-setting plastic polymerises completely. The finished baseplate tray with the handle is removed. Its borders are processed.

EFFECT: by reducing plastic pressure on the prosthetic bed tissues, method enables providing the higher quality of the produced functional patterns with total and partial adentia, reducing the time required for the baseplate tray processing.
