Impact of fabrication procedures on residual monomer elution of conventional polymethyl methacrylate (PMMA) —a measurement approach by UV/Vis spectrophotometry

ConclusionsThe fabrication procedure (pouring/injection) showed the strongest correlation to the MMA elution (r = 0.500), followed by polishing (r = 0.243), the pressure during polymerization (r = 0.109) and the storage medium (r = 0.053).Clinical relevanceHigher MMA elution may increase the risk of chemical irritations, allergic reactions and hypersensitivities of the oral mucosa. Technicians and dentists should be aware about the elution differences dependent on the fabrication procedure.
