POSTOPERATIVE FIXATION AFTER REPOSITIONING OF PREMAXILLA IN A PATIENT WITH BILATERAL CLEFT LIP AND PALATE - CASE REPORT.

ABSTRACT

This article presents orthodontic-surgical treatment in an eight-year-old patient with bilateral cleft lip and palate where premaxilla was surgically repositioned in the mixed dentition stage. By cranial and dorsal insertion of the premaxilla were created satisfactory occlusal relationship for ongoing eruption of permanent teeth, together with functional lip closure, improved pronunciation and a positive change in appearance of the centrofacial area. Reposition of premaxilla was associated with bilateral alveolar bone grafting of the cleft defect with cancellous bone from the iliac crest. Based on the model surgery were prepared rigid orthodontic wires, which ensured postoperative fixation of the segments of the upper jaw. The patient was wearing band fixed appliance for another 6 months after surgery. Healing was uncomplicated, the new position of the premaxilla was stable and more physiological. This procedure was friendly for a child patient and did not require fixation of the jaw segments by Sauer splint.
