目的：对190例单侧唇腭裂患者进行了唇腭裂相关恒牙萌出的研究，这些患者在牙槽骨移植时恒牙尚未萌出。在这些患者中的162例，骨缺损的宽度进行了比较谁接受了手术暴露的尖牙和那些其尖牙萌出natural.Results患者之间：150例（78.9%），需要在36例（18.9%）的手术暴露后，骨移植后自然萌出的裂相关尖牙。两名患者的裂相关犬齿尚未萌出。2例患者失访。鼻侧骨缺损显着更广泛的患者进行手术暴露的唇腭裂相关的永久犬齿比那些唇腭裂相关的永久犬齿爆发natural.Conclusions：目前的研究结果表明，鼻侧裂宽度相关的永久犬齿唇腭裂儿童手术暴露的需要。
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.
