The aims of this study were to (1) Evaluate the elastic modulus of different EVA commercial brands used for custom\u2010fitted mouthguards, and (2) Evaluate whether the different EVA brands can influence the stress and strain generated during an impact simulated by three\u2010dimensional finite element analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The elastic modulus of five EVA commercial brands (Essence<jats:sup>\u00ae<\/jats:sup>, Bio\u2010Art<jats:sup>\u00ae<\/jats:sup>, Proform<jats:sup>\u00ae<\/jats:sup>, PolyShok<jats:sup>\u00ae<\/jats:sup>, and Erkodent<jats:sup>\u00ae<\/jats:sup>) were calculated through uniaxial tensile tests. The obtained values were evaluated statistically by Kruskal\u2013Wallis and Dunn's test. A three\u2010dimensional model of the anterior maxilla was created using the Rhinoceros 5.0. A 3\u00a0mm custom\u2010fitted mouthguard was simulated. The three\u2010dimensional volumetric mesh was generated using the Patran software (MSC.Software) with isoparametrics, 4\u2010noded tetrahedral elements, and exported to Marc\/Mentat (MSC.Software) as element number 134. A non\u2010linear dynamic impact analysis was performed in which a rigid object struck the central incisor at a speed of 5\u00a0m\/s. The stresses were evaluated by the modified von Mises criteria, and the strains were also recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Statistically significant differences were observed for elastic modulus values (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001).

Stresses and strains generated in the model with mouthguards were significantly lower than the model without a mouthguard regardless of the commercial brand. There was no significant difference in the stress and strain on the enamel and dentin with the different EVA brands. The shock absorption ability was high for all the brands (more than 80%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The custom\u2010fitted mouthguards, independently
