An anterior segmental osteotomy may be complicated by malpositioning, bleeding, perfusion deficiencies, periodontal defects(dehiscence), devitalized teeth, oronasal fistula, and nonunion(delayed union). If periodontal defects occur after surgery, thorough hygiene and good nutrition are all that can be recommended until primary healing has occurred. However, a soft tissue graft might be needed at the defect site when the periodontal defects do not heal properly. We reported a patient who showed an excellent prognosis after undergoing a palatal mucosa graft accompanied by laterally positioned flap as a result of a dehiscence that occurred after an anterior segmental osteotomy.
