Tooth-borne Interdental Distraction Osteogenesis Along Arch Curvature for Wide Alveolar Clefts Reduction
Sponsor: Ain Shams University
Summary
This clinical study provided a modified simple and small appliance for reduction of wide alveolar clefts in cleft lip and palate patients, making the grafting procedure of better prognosis and increase its success rate.

Interventions
Tooth borne Interdental distraction appliance with mini hyrax screw
This study aimed to provide a new design of a tooth-borne, custom-made distractor that could be easily constructed and rigid enough for controlled segment transport. After cases' selection, arch expansion was done first. Following expansion, preparation of the osteotomy site was done, through inducing root divergence at site of interdental osteotomy. Osteotomies were performed under general anesthesia using piezo-surgery, there were 2 osteotomies in a L-shape; interdental vertical osteotomy mesial to 1st molar and a horizontal one above apices of teeth in the transport segment. The distraction protocol was a latency period of 7 days, after which appliance activation started with a distraction rate of 0.4 mm/day with a rhythm of twice daily. Activation proceeded till teeth at the edge of the cleft came into contact. Then the appliance was fixed in place for a 3 months consolidation period.
