Although the management of the alveolar cleft remains controversial secondary alveolar bone grafting is the most widely accepted approach. The results of a series of 71 secondary alveolar bone grafts performed between 1990 and 2001 on 58 patients with complete cleft lip and palate 13 of which were bilateral are presented. Bone grafts were assessed when the canine tooth had fully erupted using periapical dental radiographs.The occlusal level of the newly obtained interdental bone of each grafted cleft was recorded and categorised in accordance with the Oslo grading system as described by Bergland. In addition the basal level of each bone graft was recorded. In this way total bone graft height was measured and each graft was categorised with respect to the desired normal height of noncleft interdental alveolar bone. This modified analysis grades more precisely the efficacy of secondary alveolar bone grafting and helps to identify and categorise those patients with insufficient bone for dental, orthodontic and orthognathic rehabilitation and those who may require further investigation and regrafting.
尽管牙槽嵴裂的治疗仍存在争议，但二期牙槽骨植骨是目前最广泛接受的治疗方法。本文报告了1990年至2001年间对58例完全性唇腭裂患者进行的71例二期牙槽骨植骨手术结果，其中13例为双侧牙槽嵴裂。当尖牙完全萌出时，使用根尖片对植骨情况进行评估。记录每个植骨裂隙新获得的牙间骨的咬合水平，并根据Bergland描述的奥斯陆分级系统进行分类。此外，记录每个骨移植的基底部水平。通过这种方式测量了骨移植的总高度，并根据非裂隙牙间牙槽骨的理想正常高度对每个移植进行分类。这种改良分析更精确地评估了二期牙槽骨植骨的疗效，并有助于识别和分类那些骨量不足、无法进行牙齿、正畸和正颌康复的患者，以及那些可能需要进一步检查和再次植骨的患者。
