Oral and maxillofacial surgeons are the specialists par excellence for the treatment of injuries of the face, the jaws, the mouth, and the teeth, because on one hand of the specific dental knowledge they have, and on the other hand of their extensive training during their specialization, in the wider head and neck surgery. Knowledge and familiarity of the surgeon with dental occlusion, that is the way maxillary teeth articulate with the correspondent mandibular teeth, constitutes the decisive factor of the puzzle which the oral and maxillofacial surgeon is asked to solve, when he faces complicated fractures of the viscerocranium. Fractures of the mandible, the maxilla, the orbits, the cheekbones (zygomatic bones), and the nasal bones, and of the middle third of the viscerocranium in general, as well as extensive lacerations of the soft tissues of the face and the neck, are just some of the traumatology emergencies of the viscerocranium faced by oral and maxillofacial surgeons. Childhood injuries occurring during sports, game in general at school, road traffic accidents with bicycle etc., usually include also dental or maxillofacial trauma. Younger children are often subject to injuries to the teeth or the underlying hard and soft tissues as well, after referred falls. Such traumatic injuries can usually be treated effectively in an oral and maxillofacial surgery practice, by avoiding the psychologically charged for the child setting of a Hospital’s Emergency Department.
