The aim of this work was to examine the possibility of modification of commercial denture base materials with itaconic acid esters, in order to obtain materials with lower toxicity and higher biocompatibility. Despite their relatively higher price compared to methacrylates, itaconic acid and itaconates are materials of choice for environmentally friendly applications, because they are not produced from petrochemical sources, but from plant products. A commercial system based on poly(methyl methacrylate) was modified using ditetrahydrofurfuryl itaconate (DTHFI), whereby the ratio of DTHFI was varied from 2.5 to 10 % by weight. Copolymerization was confirmed using FTIR spectroscopy, while SEM analysis showed the absence of micro defects and pores in the structure. The effects of the itaconate content on the absorption of fluids, the residual monomer content, thermal, dynamic-mechanical and mechanical properties (hardness, toughness, stress and elongation at break) were investigated. It w...as found that the addition of DTHFI significantly reduced the amount of residual methyl methacrylate, which made these materials less toxic. It was shown that increasing the DTHFI content resulted in materials with decreased glass transition temperatures, as well as with decreased storage modulus, ultimate tensile strength and impact fracture resistance; however the mechanical properties were in the rang prescribed by ADA standards, and the materials could be used in practice. The deterioration in mechanical properties was therefore worthwhile in order to gain lower toxicity of the leached monomer.
