Abstract Introduction The ability to induce a callus in bone (by an osteotomy or sectioning) and then distracting the proximal and distal ends is known as callatosis or distraction osteogenesis. Intraoral distraction devices used in mandibular hypoplasia would avoid significant skin scars, provide cosmetic and functional advantages with better patient compliance. Material Method Five patient of mandibular hypoplasia are selected and intraoral distraction devices were placed after osteotomy. Distraction was carried out after 7 days latency period at a rate of 1mm/day (0.5 twice). Devices were removed after 8 week of consolidation period. Results and Observation All patients suffered from hypoplastic mandible. The distraction carried out varies from 1017mm. In two patient distraction devices applied bilaterally and in three patient unilaterally. Anterior open bite developed in two cases and appliance failure occur in one case. Disscussion Mandibular lengthening with distraction osteogenesis in mandibular hypoplasia is a significant alternative to traditional surgical technique.
