RESUMO
Oligodontia may cause various problems during orthognathic surgery because it may be difficult to fix the surgical guide splints. The aim of this clinical report was to present an alternative technique for intermaxillary fixation of a patient with oligodontia and facial deformity. A 20-year-old male patient, whose 8 maxillary and 11 mandibular teeth were congenitally missing, was treated using bimaxillary orthognathic surgery. Before the surgical approach, fixed mandibular prosthesis containing pins on the vestibule sides of the crowns was constructed to provide anchorage for intermaxillary splint and to achieve occlusal stability and vertical dimension during the surgery. This prosthesis was also used to hang intraoral elastics during the postoperative orthodontic treatment. At the end of treatment, these pins were cut, composite restoration material was applied to camouflage the places of the pins, and the patient continued to use this prosthesis. The patient gained an appropriate facial aesthetics and oral function using multidisciplinary approach.
