Background. A significant disadvantage of dental acrylic base materials is the presence of residual methyl methacrylate monomer. In this regard, it is important to develop alternative acrylic-free base materials with increased biocompatibility and improved performance properties.
Aim. To conduct a comparative analysis of the properties of a new self-curing acrylic-free base plastic (BAP) and its analogues based on a generalised quality indicator.
Materials and Methods. Laboratory tests of base plastic samples were conducted in accordance with international standard ISO 20795–1:2013. Physical, chemical, clinical and technological indicators were determined. A comparative analysis in the qualimetric assessment system involved determining qualimetric indicators: relative standardised and qualimetric coefficients and a generalised quality indicator. The results were processed and analysed using methods of variational statistics, including the calculation of the mean value, mean square deviation and standard error of the mean. The comparison of mean values was performed using Student's t-test. The study was conducted as a private initiative of the authors, without additional funding or state registration of the research topic.
Research Ethics. All materials are approved for medical use in Ukraine in accordance with the Technical Regulations for Medical Devices, approved by Resolution of the Cabinet of Ministers of Ukraine No.753 of October 02, 2013, and comply with the requirements of Medical Device Regulation (European Union) 2017/745 and International Organization for Standardization (ISO) 10993 standards. The study was performed in vitro without the involvement of humans or laboratory animals.
Results. All materials studied met the requirements of ISO 20795–1:2013. The proposed acrylic-free plastic was characterised by the absence of residual monomer, low water absorption and solubility, and optimal clinical and technological properties. The generalised quality index was 14.164 and 4.477 bits, respectively.
Conclusions. The developed acrylic-free plastic demonstrates a high level of biocompatibility and can be recommended for the manufacture of bases for removable dentures.
