Is “Bite force” a reliable parameter to compare masticatory efficiency restoration following ORIF of anterior mandibular fractures?
Objectives: Mandible is an integral part of masticatory system, and it is expected that it’s fracture will have a significant impact on occlusal forces, range of motion, muscle activity levels, and occlusion.

| Summary: | Objectives: Mandible is an integral part of masticatory system, and it is expected that it’s fracture will have a significant impact on occlusal forces, range of motion, muscle activity levels, and occlusion. The main objective of this study was to compare the efficacy of 3-dimensional (3D) miniplate and conventional miniplates for fixation of anterior mandibular fractures on the basis of bite force as a main parameter. Methods: 66 patients having isolated anterior mandibular fractures were randomized into two groups equally: Conventional miniplates and 3D miniplates. The bite force at incisor, canine, and molar regions was measured preoperatively and postoperatively at weekly intervals until the sixth week, and the mean bite force as well as changes in mean bite force were compared between two groups. Results: An increase in bite force was noted at each subsequent follow up in both the groups across all sites. Statistically significant difference was found in mean bite force values between both the groups during mid-follow up period. The difference in changes in the mean bite force too was observed to be statistically significant during the mid to late follow up period. Interpretation & conclusion: Bite force is a reliable parameter to assess restoration of masticatory efficiency following open reduction and internal fixation (ORIF). 3D miniplates when used in anterior mandibular fractures management are efficient enough to withstand masticatory forces throughout the healing process, providing better stability of fractured segments against torsional forces during immediate post-operative period. |
