Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, particularly to orthopaedic dentistry, maxillofacial prosthesis; can be used for making a hollow basis as a complete removable post-examination prosthesis, and a partial removable prosthesis of the upper jaw. Imprint is removed, the border of the imprint borders is waxed. Plastic base of the prosthesis repeating the defect contours is made. After fitting and verifying the fixation of the plastic basis in the oral cavity at the basal portion in the projection of the defect, a wax pattern is made, which restores the alveolar process and the palate configuration; a wax composition of the hard palate and the alveolar process of the prosthesis is formed on the wax pattern, then wax composition is changed to plastic by polymerisation. Prosthesis is made in several stages, where at first stage flat base is made, which repeats defect outlines, at the second stage, a frame is made - a volumetric part from wax to form a missing alveolar part and sky from wax, on the surface of the frame a wax plate is pressed, repeating contours of the volumetric framework, at the third stage the frame is removed, and wax plate is replaced by plastic method of hot polymerisation, and then produced plastic plate and flat base are connected into common hollow structure by means of cold polymerisation, with subsequent closing of points of connection of parts with wax at clinical stage and replacement of wax by plastic hot polymerisation at laboratory stage. 
     EFFECT: method allows improving adaptation to a prosthesis due to reduced weight of the prosthesis.

The shaft with the circular brushes installed thereon is rotated forming a liquid film on the bristles of each brush located above the level of the cleaning liquid. A polluted gas medium is fed into the intake branch pipe, passing above the cleaning liquid oil level through the bristles with the liquid film of each brush. The purified gaseous medium is discharged through the outtake branch pipe after passing through the bristles with the liquid film of all circular brushes.
