Secondary bone grafting of a residual alveolar cleft has become a well established procedure. However, little attention has been paid to the benefits of these bone grafts in patients with clefts of the lip and alveolus only. This retrospective and comparative study includes 21 patients who had received a secondary or a late secondary bone grafting procedure from tibia and whose mean clinical and radiographic follow-up after the bone graft was 5.5 years. Eighteen patients treated without bone grafting served as controls. Length and width of cleft, presence or absence of permanent lateral incisor, size of nasal floor bony defect, and interdental alveolar bony height in the cleft area were investigated. The results showed that bone grafting was indicated particularly in wide clefts with missing lateral incisors. Eruption of a tooth close to the cleft was facilitated and the bony support for teeth neighboring the cleft was improved. In some cases, additional support of the alar base of the nose was achieved and closure of an oronasal fistula facilitated. A further advantage of bone grafting of clefts of the primary palate was that it might make it possible to insert a titanium implant carrying an artificial tooth in the cleft area.
残余牙槽嵴裂的二期骨移植已成为一种成熟的手术方法。然而，对于仅唇裂和牙槽嵴裂患者进行这些骨移植的益处却鲜有关注。这项回顾性对比研究纳入了21例接受了来自胫骨的二期或晚期二期骨移植手术的患者，骨移植术后的平均临床和影像学随访时间为5.5年。18例未接受骨移植治疗的患者作为对照。对裂隙的长度和宽度、恒侧切牙的有无、鼻底骨缺损的大小以及裂隙区域的牙槽骨间高度进行了研究。结果表明，骨移植尤其适用于伴有侧切牙缺失的宽裂隙。靠近裂隙的牙齿萌出得到促进，裂隙邻近牙齿的骨支持得到改善。在某些情况下，还实现了对鼻翼基部的额外支持，并促进了口鼻瘘的闭合。原发性腭裂骨移植的另一个优点是，有可能在裂隙区域植入带有假牙的钛种植体。
