Objective: Eruption of cleft-associated permanent canines was studied in 190 patients with unilateral cleft lip/palate and whose permanent canines had not erupted at the time of alveolar bone grafting. In 162 of these patients, width of bone defect was compared between patients who underwent surgical exposure of canines and those whose canines erupted naturally. Results: Cleft-associated canines naturally erupted after bone grafting in 150 patients (78.9%) and required surgical exposure in 36 patients (18.9%). Cleft-associated canines had not yet erupted in two patients. Two patients were lost to follow-up. Nasal-side bone defects were significantly wider in patients who underwent surgical exposure of cleft-associated permanent canines than in those whose cleft-associated permanent canines erupted naturally. Conclusions: The present results suggest that nasal-side cleft width is related to the need for surgical exposure of permanent canines in children with cleft lip/palate.
