Fracture Fixation Technique and Chewing Side Impact Jaw Mechanics in Mandible Fracture Repair.

ABSTRACT: Lower jaw (mandible) fractures significantly impact patient health and well-being due to pain and difficulty eating, but the best technique for repairing the most common subtype-angle fractures-and rehabilitating mastication is unknown. Our study is the first to use realistic in silico simulation of chewing to quantify the effects of Champy and biplanar techniques of angle fracture fixation. We show that more rigid, biplanar fixation results in lower strain magnitudes in the miniplates, the bone around the screws, and in the fracture zone, and that the mandibular strain regime approximates the unfractured condition. Importantly, the strain regime in the fracture zone is affected by chewing laterality, suggesting that both fixation type and the patient's post-fixation masticatory pattern-ip
