Patients affected by severe maxillary atrophy and skeletal malocclusion have been widely treated by simultaneous orthognathic surgical procedures, interpositional bone insertion and immediate or delayed implant placement. Although several authors have described that the "quad" technique using 4 zygomatic fixtures as an effective way to fully rehabilitate the severe atrophic maxilla, there are still no experiences relative to the use of zygomatic fixtures associated to maxillary osteotomies in case of large skeletal discrepancy. The aim of this study is to report a 1-step surgical rehabilitation of severe atrophic maxilla by means of Le Fort I osteotomy for maxillary forward repositioning and simultaneous insertion of 4 zygomatic implants with immediate prosthetic loading.
患有严重上颌骨萎缩和牙颌面畸形的患者已广泛接受同期正颌外科手术、植入性骨移植以及即刻或延期种植体植入治疗。尽管有多位作者描述了使用4枚颧骨固定装置的“四边形”技术是全面修复严重萎缩性上颌骨的有效方法，但在存在严重骨骼差异的情况下，关于颧骨固定装置与上颌骨截骨术联合使用的经验仍然较少。本研究的目的是报告一种通过Le Fort I截骨术对上颌骨进行前徙复位并同时即刻植入4枚颧骨种植体并进行即刻修复加载，对严重萎缩性上颌骨进行一步法手术修复的方法。
