Numerous methods have been attempted to identify the best time for secondary alveolar cleft bone grafting, including chronological age, skeletal age, and dental age. However, few studies have employed objective methods of assessment that would permit statistical analysis. Fifty-nine patients with clefts of the alveolus who acquired secondary alveolar cleft grafts at the Lancaster Cleft Lip and Palate Clinic were studied. A total of 74 affected areas from 15 bilateral and 44 unilateral alveolar cleft patients were available. Timing of the graft was determined utilizing root development of the involved canine, as compared to crown length, from a high quality pre-graft radiograph taken no more than six weeks prior to surgery. A Post-graph radiograph exposed approximately 2 years post-surgery was digitized to assess the final bony architecture.
