Aim: This paper concerns orthodontic alignment of the maxillary lateral incisor on the cleft side of a lip and alveolar cleft patient after a secondary autogenous cancellous bone graft at the late stage of mixed dentition. Subject and Treatment: The patient was a Japanese girl 9 years 7 months of age who presented at the authors’ clinic with a repaired lip and alveolar cleft and an incisor crossbite. At 12 years of age, a secondary bone graft of the alveolar ridge was performed using bone harvested from the iliac crest. At 14 years 7 months of age, a conventional fixed appliance was placed. Results: The lateral incisor on the cleft side was brought to the line of occlusion by orthodontic alignment. A Class I molar relationship on both sides and a satisfactory facial profile were achieved. After a 2-year retention period, the occlusion and esthetics were maintained. Five years after grafting, however, a satisfactory bone level was not achieved due to positioning of the root of the lateral incisor, which was not completely upright in the bone graft area due to root tipping.
