Secondary alveolar bone grafting: Radiographic and clinical evaluation.

Abstract

Introduction:Secondary bone grafting of maxilla and residual alveolar clefts at the stage of transitional dentition was first introduced by Boyne and Sands. The aim of this prospective case control study was to clinically and radiologically evaluate the success rate of anterior iliac crest graft in primary alveolar cleft.Methods and Material:In this study we evaluated 10 patients who underwent secondary alveolar bone grafting for various types of cleft palate with autologous iliac crest graft. Type of septum measured radiologically was taken as the outcome measure.Results:Postoperative radiographic evaluation revealed Type I inter alveolar septum in 7 cases (87.5%), with complete unilateral cleft lip, palate and alveolus. Non-eruption of canine occurred in 5 patients (50%). Periodontal Examination revealed presence of pocket formation (less than 4 mm) and Grade II mobility in 2 cases (20%).Conclusions:In conclusion, secondary alveolar bone grafting done during the time of transitional dentition, before the eruption of permanent canine is an excellent treatment modality.
