OSORIO NARANJO, Alejandro; GUERRERO IBARRA, Jorge y SANTOS ESPINOZA, Alejandro. Influence exerted by thermal changes in the transverse deflection of acrylic materials used for denture bases, with and without metallic inserts. Rev. Odont. Mex [online]. 2014, vol.18, n.3, pp.170-174. ISSN 1870-199X.
The aim of the present in vitro study was to determine whether thermal changes influence the transverse deflection of two different brands of acrylic used for denture bases, with and without metallic inserts, after having been subjected to a thermo-cycling period with temperature changes. 40 acrylic samples were processed according to ADA's specification number 12. Four groups were made up, two with Lucitone 199 and two with ProBase Hot. Results were subjected to one-way ANOVA statistical analysis and comparison of Turkey groups with a value of (p > .001). Conclusion: Both acrylic materials used for denture bases fulfill specifications of ADA's norm number 12. Metallic inserts allowed the decrease of the acrylic deflection and thermal changes considerably affected physical characteristics.
