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.
