The Effects Of Some Methacrylate Monomers Used As Liquid Component On Tensile And Flexural Strengths Of A Poly (Methyl Methacrylate) Denture Base Resin

摘要

This study was conducted to observe the effect of different monomers on tensile and flexural strengths of poly (methyl methacrylate) (PMMA) denture base resin when they were used as a liquid component. A conventional heat-cured denture base polymer powder was mixed ethyl, isobutyl and tert-butyl methacrylate monomers, respectively. After the polymerization process was completed, the tensile and flexural strengths values of these specimens were compared with those that of PMMA resin specimens polymerized with methyl methacrylate monomer (MMA). Each group was subjected to tensile strength and flexural strength tests using a cross-head speed of 50 mm min~(-1) using a universal testing machine.
