DENTAL CUVETTE Russian patent published in 2013 - IPC A61C13/16 

FIELD: medicine.

SUBSTANCE: invention relates to orthopedic dentistry and is intended for manufacturing plastic basis of removable prosthesis by methods of compression or injection moulding of basis plastic and its further polymerisation in forming dental cuvette. Dental cuvette consists of upper and lower halves of hollow case, in whose parting plane there are inlet and outlet holes for plastic and air and holes in bottoms of cuvette halves, connector-fixers for accurate connection of case halves and fastening elements for their assembly. Cuvette includes detachable O-shaped compression box with two walls-partitions in box cavity, dividing box cavity into three compartments with bottom holes, and two projections-guides on external surface of box wall for fixation of box position in lower half of cuvette case. One central and three peripheral conic holes are located in the bottom of upper cuvette half. Bottoms or walls of cuvette case halves have embedded irradiators of ultrasonic fluctuations and/or metal inserts for transmission of ultrasonic fluctuations from embedded or laid on irradiators of ultrasound into cuvette cavity.

EFFECT: reduced probability of formation of cavities in massive of basic plastic and simplification of its polymerisation procedure due to application of ultrasonic polymerisation.
