Background Being edentulous causes progressive bony resorption in maxillae, which can lead to altered maxillomandibular relationships. Discussion should consider Le Fort I osteotomy with inlay grafts for a better success rate. Thus, this article introduces a technical note in improving the success rate. Case Report The presented technical note permits transformation of the surgery in a conventional Le Fort I with a simple fixation not only of the grafts but also of the osteotomy. The surgical steps are explained as well as the follow-up results. Discussion Adding additional wire anchorage around bone grafts greatly improved our success rate and reduced our operative time. Bone grafting concurrently with Le Fort I osteotomy immediately improved the facial skeletal profile. Several in vitro studies have shown that galvanic corrosion does not play a significant role when combining stainless steel and titanium. Our novel technique is relatively simple and can be easily picked up by young surgeons.
背景 无牙颌会导致上颌骨进行性骨质吸收，进而可能导致上颌下颌关系改变。讨论应考虑采用嵌体移植的勒福Ⅰ型截骨术以提高成功率。因此，本文介绍一种提高成功率的技术说明。病例报告 所呈现的技术说明允许将传统勒福Ⅰ型手术转变为不仅简单固定移植骨而且固定截骨的手术。文中解释了手术步骤以及随访结果。讨论 在骨移植周围增加额外的钢丝锚固极大地提高了成功率并缩短了手术时间。与勒福Ⅰ型截骨术同时进行骨移植立即改善了面部骨骼轮廓。多项体外研究表明，不锈钢和钛联合使用时，电偶腐蚀不起重要作用。我们的新技术相对简单，年轻外科医生能够轻松掌握。
