Biomechanical evaluation of magnesium plates for management of mandibular angle fracture

Published:November 16, 2021DOI:https://doi.org/10.1016/j.bjoms.2021.11.001

      Abstract

      The aim of this study was to evaluate the efficacy of magnesium plates for the management of fractures of the mandibular angle. Fresh sheep hemimandibles were divided into 7 groups and a biomechanical cantilever bending test was used for the groups: Group 1 included fractured hemimandibles fixed at the angle with a single 1mm magnesium miniplate; Group 2 had fixation with a 1mm double magnesium miniplate; Group 3 used a 2mm thick single magnesium miniplate; Group 4 used double 2mm magnesium plates; Group 5 each had a single 1mm thick titanium plate; Group 6 used 1mm thick double titanium plates; and Group 7 comprised intact hemimandibles. Each group was tested using universal testing machine yield loads; yield displacements and stiffness were compared using one way analysis of variance (ANOVA) Group 1 (1mm single magnesium plate) and Group 2 (1mm double magnesium plates) showed lower stability than other groups, while the 2mm magnesium plate showed stability similar to the corresponding 1mm titanium plate. Pure magnesium has good mechanical properties and when it is designed properly it can be used for the management of mandibular fracture.
