To demonstrate a method for reduction of wide alveolar clefts prior to bone grafting. This method aims to facilitate bone grafting and achieve adequate soft tissue coverage of the graft with attached gingiva.
Treatment of a patient with bilateral cleft lip and palate with a severe alveolar defect on the left side is illustrated. Distraction osteogenesis was used to mesialize the left segment so that the alveolar cleft was reduced to a minimum. After a 10-week retention period, bone grafting of the reduced alveolar defect was successfully performed. After consolidation of the bone graft, the alveolar cleft was found to have an osseous closure with adequate soft tissue coverage.
In patients with a wide alveolar cleft, soft tissue coverage with keratinized mucosa can be more readily assured by reducing the alveolar cleft by callus distraction to mesialize the lateral segment prior to bone grafting.
展示一种在骨移植前缩小宽牙槽嵴裂的方法。该方法旨在便于骨移植，并实现移植骨有附着龈的充分软组织覆盖。
举例说明了对一名双侧唇腭裂且左侧存在严重牙槽嵴缺损患者的治疗。采用牵张成骨术使左侧骨段向中线移动，从而将牙槽嵴裂缩小至最小程度。经过10周的保持期后，成功对缩小后的牙槽嵴缺损进行了骨移植。骨移植巩固后，发现牙槽嵴裂实现了骨性封闭且有充分的软组织覆盖。
对于宽牙槽嵴裂患者，在骨移植前通过骨痂牵张使外侧骨段向中线移动以缩小牙槽嵴裂，能更轻易地确保角化黏膜的软组织覆盖。
