Objective: To evaluate the effect of alveolar extension palatoplasty technique and Bardach two flap palatoplasty technique in a split mouth design on the eruption of primary teeth after 6 months of surgery. Materials and Methods: Eight cleft palate patients aged 9-12 months were operated with alveolar extension palatoplasty technique on one side and with Bardach technique on the other side. The patients were followed up clinically at first week, second week, first month, third month, and sixth month. Rubber base impression was taken for the maxillary arch at baseline,1 and 6 months. Both sides were compared to each other in the eruption pattern of primary first molar and canine at baseline,1 and 6 months, then data was collected and statistically analyzed. Results: Alveolar extension palatoplasty technique led to significantly faster teeth eruption than Bardach technique. Conclusion: Alveolar extension palatoplasty technique gave more favorable eruption pattern than Bardach technique.
