Abstract: Objective: The aim of the present study was to compare four methods of fixation in mandibular body fractures. Study design: Mechanical and photoelastic tests were performed using polyurethane and photoelastic resin mandibles, respectively. The study groups contained the following: (I), two miniplates of 2.0mm; (II) one 2.0mm plate and an Erich arch bar; (III) one 2.4mm plate and an Erich arch bar, and (IV) one 2.0mm plate and one 2.4mm plate. The differences between the mean values were analyzed using Tukey's test, the Mann-Whitney test and the Bonferroni correction. Results: Group II recorded the lowest resistance, followed by groups I, IV and III. The photoelastic test confirmed the increase of tension in group II. Conclusion: The 2.4mm system board in linear mandibular body fractures provided more resistance and the use of only one 2.0mm plate in the central area of the mandible created higher tension.
