Background. The effectiveness of orthopedic treatment of edentulous patients depends on the properties of the basic materials. The main group of materials for manufacturing of such structures is acrylic plastics of thermal polymerization. However, many years of experience in the use of plastics have revealed a number of shortcomings. One of the main shortcomings is insufficient functional durability of prostheses, and as a consequence the fragility of acrylic constructions. At present, more and more dentists use nonacrylic thermoplastics, which can improve the functional quality of full removable dentures, as well as, avoid the above disadvantages of acrylic basic plastic.

Aim. The work is devoted to the study of comparative clinical effectiveness of dental prosthetic in edentulous patients using a variety of basic materials for the production of removable dentures.

Material and methods. In this work we used the following materials – «Deflex Acrylate» and «Vertex Ther- mosense» - nonacrylic thermoplastic plastic.

The main characteristics of these materials are the absence of free monomer, high density and lightness, opportunity to repair it by any technology. During making dentures of «Vertex Thermosense» and «Deflex Acry- late» all clinical and laboratory stages were carried out by conventional methods.

Ready dentures were polished and had been put in the mouth. All the patients noted significant improvement of fixation and stabilization of dentures, lack of irritation of prosthetic bed and high aesthetic quality.

The subjective test «BOFSAT» (A.G. Zaitsev, 1992; A.B. Belikov, 2003) and electromyographic studies of chewing muscles (m. masseter) (taking into account the period of adaptation of patients to the prostheses) were used for evaluating the effectiveness of dental prosthetics of patients with complete absence of teeth with these basic thermoplastic materials.

Results. As a result of the performed work it can be concluded that the use of the basic thermoplastic materials, namely «Vertex Thermosense» and «Deflex Acrylate», allows getting more rapid adaptation of the patient to full removable dentures due to better fixation and stabilization.

These materials are biocompatible, non-toxic, they practically do not cause allergic responses and can be used in patients with hypersensitivity to acrylates. Prostheses from thermoplastic material are very well processed and polished, which significantly improves the quality of dentures, as attachment of microorganisms to denture base is hampered and it reduces the risk of inflammation of the mucous membrane of prosthetic bed. Prostheses made of «Vertex Thermosense» and «Deflex Acrylate» are easily exposed for repairing.

Conclusion. Based on the results of our comparative clinical study using of base material «Vertex Thermosense» and «Deflex Acrylate» in the clinic of prosthetic dentistry in treatment of edentulous patients can be recommended.
