In this study, 16 cases of unilateral alveolar cleft with cleft lip and palate were repaired with autografts of cancellous bone (13 cases) or hydroxyapatite (3 cases). The grafts were covered by reflected mucoperiosteal flaps and a mucosal flap from the upper lip. Twelve of the thirteen cases were followed up for 1-5 years. Nine of whom using cancellous bone had bony continuity of the maxilla and 7 cases erupted permanent maxillary canines within the area of autografts. None of the 3 cases using hydroxyapatite erupted a canine tooth. The results showed that autograft was better than hydroxyapatite in terms of maxillary canine eruption.
在本研究中，16例单侧牙槽嵴裂合并唇腭裂患者接受了松质骨自体移植修复（13例）或羟基磷灰石修复（3例）。移植物由翻转的黏骨膜瓣和上唇黏膜瓣覆盖。13例患者中的12例接受了1至5年的随访。其中使用松质骨的患者中有9例上颌骨实现了骨连续性，7例在自体移植区域内萌出了上颌恒牙尖牙。使用羟基磷灰石的3例患者均未萌出尖牙。结果表明，在促进上颌尖牙萌出方面，自体移植优于羟基磷灰石。
