EVALUATION OF TWO DIFFERENT DISTRACTION OSTEOGENESIS TECHNIQUES IN TREATMENT OF UNILATERAL ALVEOLAR CLEFT

Purpose: This study was planned to compare the use of bone borne distractor versus hybrid distractor in repair of unilateral alveolar cleft. Materials & Methods: A 16 patients with unilateral alveolar cleft were included in this study. They were divided into two equal groups according to the type of distractor used, Group I: in which the bone- borne distractor (Liou cleft distractor) was used for alveolar cleft repair. Group II: in which the custom made hybrid distractor was used. Results: Stage I distraction: after three months, showed significant difference in the width of the cleft side in both groups as P-value was 0.007 in group I and P-value was 0.001 in group II. No significant differences in the vitality and mobility of teeth in both groups. The amount of relapse in the regenerate area at the different observation periods 3 and 6 months between both groups were statistically significant (P-value…
