Prospective data will be collected in 314 patients suffering from bilateral (double) mandibular fracture randomly treated either with non-rigid fixation on both fracture sides or a combination of rigid fixation on one side and non-rigid fixation on the other side. This is a study where patients will be treated per randomization to one of the two established treatments and followed for further clinical examination post-operatively at 6 weeks and 3 months after the intervention.
