Alveolar width deficiencies have generally been corrected by guided tissue regeneration or bone augmentation with and without membranes. The use of distraction osteogenesis is proposed for the correction of horizontal alveolar width defects. In this case report, horizontal bone generation by distraction osteogenesis was achieved prior to implant placement. Following implant restoration, favorable bone response was observed after two years of function. Distraction osteogenesis to widen the alveolus may prove to be a clinically useful treatment option in selected cases.
牙槽嵴宽度不足通常通过引导组织再生或使用或不使用膜的骨增量术来矫正。有人提出采用牵张成骨术来矫正水平牙槽嵴宽度缺损。在本病例报告中，在植入种植体之前通过牵张成骨术实现了水平骨生成。种植体修复后，经过两年的功能使用观察到了良好的骨反应。在某些特定病例中，牵张成骨术扩宽牙槽嵴可能被证明是一种临床上有用的治疗选择。
