Abstract:
The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.
