Medial Trap Door Technique to Harvest a Cancellous Bone Graft From the Anterior Iliac Crest.

Abstract

Alveolar bone grafting (ABG) in cleft lip and palate patients allows for the facilitation of eruption of the canine and sometimes eruption of the lateral incisor. It provides bony support to the cleft raising the alar base of the nose and also facilitates the closure of an oro-nasal fistula. Many report at a time when late alveolar bone grafting is the only option to overcome the bony defect mainly due to their socioeconomic concern. Autologous bone graft for alveolar bone grafting harvested from the anterior iliac crest using the medial trap door technique has many advantages over other techniques of harvesting bone graft from the anterior iliac crest. In this case report we have discusseda case of bone graft harvesting from the anterior iliac crest using the medial trap door technique for late secondary alveolar bone grafting.
