A case of mandibular fracture surgically consolidated in a wrong position resulting in craniomandibular disorders is reported. The inadequate surgical alignment of the healed bony segments caused a malocclusion. This changed the original neuromuscular system such that compensatory mechanisms began to change the whole balance of the organism. The patient presented a mandibular crossbite, an asymmetry of the face, and extensive alteration of muscular, articular, and postural function. The bony malunion and malocclusion were treated using an interdisciplinary surgical-orthodontic treatment for correcting functional disorders and aesthetic deformity. Electromyography and computerized mandibular scanning were used to evaluate improvement of the muscular activity, during rest and function, and of the mandibular kinesiology. Timing of surgical treatment and adequate fixation and immobilization of fracture segments are very important to avoid complications such as infection, delayed union, nonunion, malunion, skeletal discrepancies, nerve injury, and (rarely) ankylosis. The surgical approach should be based on the general criteria of traumatologic therapy, restoring the original bone shape and the right occlusal relations as soon as possible.
