Wider alveolar clefts/fistulae and maxillary dentoalveolar defects pose problems in achieving complete closure because of the requirement of a greater volume of bone as a graft. Segmented osteotomies have been used successfully for the repositioning of minor segments; however, in major segmented movements, the closing of the flap and the blood supply of the osteotomized segment may be compromised. Interdental distraction osteogenesis has overcome this problem by creating a segment of new alveolar bone and complete approximation of wider alveolar defects. This case report shows an effective and efficient way of distraction using a modified Hyrax appliance.
