A total of 178 (30%) had cleft lip and alveolus only, and 412 (70%) had cleft lip and alveolus with cleft palate. Secondary alveolar bone grafting was performed in 219 clefts among 191 children. The mean age at first SABG was 9.8\u2009\u00b1\u20091.1 years. Fourteen children (7%) underwent regrafting. The cumulative probability of regrafting was 10% (95% confidence interval, 6%-16%) up to 6 years of follow-up.
