Our results of bone grafting to the alveolar process during the mixed dentition were investigated in 55 consecutively treated patients (66 clefts). The amount of remaining bone and gingival retraction at the tooth mesial to the cleft after 3 and 12 months was measured and correlated with the following anatomical conditions present during surgery: width of the cleft, rotation of the adjacent incisor, stage of eruption of the tooth distal to the cleft. It was also considered if any deciduous lateral incisor or canine was extracted during surgery and if any flap dehiscence took place postoperatively. It was found that flap dehiscence resulted in significantly less bone at 3 months and at 1 year after surgery. Furthermore, extraction of a deciduous tooth was found to be significantly correlated to less bone 1 year after surgery, in which cases there were also persisting gingival retractions. The other factors had no significant influence on the outcome of surgery.
我们对55例连续接受治疗的患者（66处腭裂）在混合牙列期进行牙槽突植骨的结果进行了研究。测量了术后3个月和12个月时裂隙近中牙齿处的剩余骨量和牙龈退缩情况，并将其与手术过程中存在的以下解剖学状况相关联：裂隙宽度、相邻切牙的旋转情况、裂隙远中牙齿的萌出阶段。还考虑了手术过程中是否拔除了任何乳牙侧切牙或尖牙，以及术后是否发生了皮瓣裂开。结果发现，皮瓣裂开导致术后3个月和1年时的骨量明显减少。此外，发现拔除乳牙与术后1年时骨量减少显著相关，在这些病例中还存在持续的牙龈退缩。其他因素对手术结果没有显著影响。
