The maxillary canines are amongst the most frequently impacted teeth, second only to the third molars. Several conservative orthodontic and surgical techniques are available to position the teeth properly in the dental arch, even in severe cases. However, when an extraction is necessary, it often leaves a critical alveolar defect of difficult management. The authors present the technique of partial maxillary osteotomy, in which a dento-alveolar segment is moved mesially, hence closing the remaining space, allowing for the formation of healthy periodontium and resulting in an adequate functional and aesthetic outcome. A case report is presented with a 10 year follow-up, proving the technique's stability in the long term.
上颌尖牙是最常受影响的牙齿之一，仅次于第三磨牙。有几种保守的正畸和外科技术可以将牙齿正确地定位在牙弓中，即使在严重的情况下也是如此。然而，当需要拔牙时，通常会留下难以处理的严重牙槽骨缺损。作者介绍了上颌部分骨切开术的技术，通过这种技术可以将牙牙槽骨段向近中移动，从而关闭剩余的空间，形成健康的牙周组织，并获得足够的功能和美学效果。报告了一个病例，并进行了 10 年的随访，证明了该技术在长期内的稳定性。
