Introduction. Plastics of cold polymerization are using in dentistry to repair (rebase) dentures, repair of prostheses, the manufacture of temporary prostheses, tires on parodontal diseases, models, and other.

Manufacturer of removable prosthesis consists of many stages. The first is impression, after that there will be some technological stages in the dental laboratory. These includes obtaining the model, setting the teeth, making a wax model, making gypsum model in the dental ditch and removing, decoction of wax, and then filling the resulting space with forming material for the manufacture of bases of the dental prosthesis or with the basic material.

The purpose of the study. The aim of the study was to conduct a comparative assessment of the physical and mechanical properties of acrylic plastics Cold polymerization to ensure the quality of orthopedic treatment of dental patients, given the clinically-oriented technology manufacturing dentures.

Results. Physico-mechanical investigations of plastics polymerized by cold temperature was researched by the following parameters: deformation with compression, bending voltage, impact viscosity, abrasion resistance, amount of residual monomer, water absorption at 360 test samples. Generalized analysis of the studied properties indicates the presence of specific qualimetrics profile for each of the plastics cold polymerization.

Conclusions. It is obvious that cold-curing acrylic plastics are widely used in the practice of a dentist as an orthopedic material for relocation and repair of dental prostheses for temporary prostheses, tires with periodontitis, models, etc. of individual spoons. Therefore the study and analysis of their physical and mechanical properties makes it possible to understand and apply the necessary material in a particular clinical situation in order to best meet the needs of orthopedic treatment. However, when using such material in any case can not be neglected modes of polymerization. Therefore, the prospects for further research are obvious and work in this aspect can be considered not only necessary but essential.
