AIM or PURPOSE: This study aimed to investigate the biomechanical stability of single standard miniplates for treating unfavorable mandibular angle fractures with varying angulations under incisal and molar loading. MATERIALSandMETHOD:Threegroupsofunfavorablemandibular angle fractures at 15°,30°and 45° angles were simulated on polyurethane models and fixated with standard miniplates placed over the superior alveolar border. Models were then subjected to incremental vertical forces up to 120 N on the first molar and incisors, separately. Displacement was recorded at 10 N intervals; load magnitudes for 1 mmand3mmdisplacements were analyzed using ANOVA andTukey’s tests. RESULTS: Under incisal loading the 30° and 45° groups required significantly less force magnitude to achieve 1 mm and 3 mmdisplacements compared to the 15° group (p<0.05, for both). Starting at 20 N, the 30° and 45° groups showed greater displacement than the 15° group (p<0.05, for both). During molar loading, displacement differences were not significant between the 15° and 30° groups, but the 45° group had significantly greater displacement from 40 N onwards (p<0.05). The load required for 3 mm displacement was notably lower in the 45° group compared to the 15° and 30° groups (p<0.05). CONCLUSION(S): Considering the study’s limitations, it can be stated that polyurethane mandibles with greater angulations in unfavorable mandibular angle fractures, fixated with a standard monocortical plate, exhibited increased displacement values under molar and incisal loadings. This underscores the need for customized treatment strategies based on fracture angulation severity and expected loading conditions, enhancing the management of unfavorable mandibular fractures.
