Dental materials science is focused on developing new and improved, already-known materials for use in the clinical practice of dentistry. Traditional treatment methods, such as crowns and fixed partial dentures, effectively restore function and aesthetics to internal teeth. This study aimed to conduct a comparative assessment of the physico-mechanical and physico-chemical properties of domestic ashless acrylic plastic with foreign analogues. Together with our partners from the accredited research laboratory of dental materials of the company "Stoma" in Kharkiv, Ukraine, we conducted a detailed analysis of ashless plastics for cold polymerization. In our research, we have studied these materials' physical and mechanical characteristics, such as surface microporosity, microhardness, light reflectance, bending stress, and tensile strength, in detail. Their physicochemical properties, such as monomer content, water absorption, ash content, linear shrinkage and specific weight, were also investigated. The research results showed that the "Modeplast" material from JSC "Stoma" turned out to be superior compared to other studied materials. It differed from Bredent's "Pi-Ku-Plast" with lower monomer content and was more potent and stable, particularly regarding water absorption and microporosity. Modeplast also proved more decisive in bending stress and tensile strength, making it a promising material for dental practice.
