Annotation:  According to new requirements of the legislation the domestic manufacturer of JSC SEZ VLAD-Miva developed the new basic material "Belakril-E GO". Having passed the first clinical tests, specialists noted a specific smell of monomer, and as a result, long adaptation of patients to removable designs of dentures. This fact motivated on search of new ways of obtaining the best quality of an artificial limb, and need of improvement of manufacturing techniques. The purpose of this work was to improve manufacturing techniques of removable designs of dentures from besprekursorny basic polymer "Belakril-E GO" and to carry out comparison with the manufacturing techniques recommended by the producer. Samples were for this purpose made of new domestic besprekursorny basic polymer "Belakril-E GO" by different technologies: compression pressing, according to the instruction of the producer; molding formation; free casting; and the developed method. The received samples were studied regarding the content of residual monomer of methylmethacrylate in comparative aspect. The received results showed, the advanced manufacturing techniques of removable designs of dentures allow to improve their quality significantly.

Keywords:  basic plastic, methylmethacrylate, ethylmethacrylate, removable artificial limbs, precursors, drug addiction, technology.
