A 55-year-old woman developed chronic infections of the maxillary sinuses with osteomyelitis resulting in extensive bone destruction and atrophy from a failed subperiosteal implant. After surgical removal of the subperiosteal implant, extensive debridement of the maxilla, and long-term antibiotic therapy, maxillary reconstruction was initiated. A Le Fort I osteotomy and downgraft was performed, and a posterior iliac bone graft was harvested and grafted to reconstruct the severely atrophic maxilla. In a later surgical procedure, maxillary and mandibular implants were placed. Implant-retained overdentures were fabricated to restore function and esthetics.
一名55岁女性因骨膜下种植失败，出现上颌窦慢性感染并伴有骨髓炎，导致广泛的骨质破坏和萎缩。在手术取出骨膜下种植体、对上颌进行广泛清创以及长期抗生素治疗后，开始进行上颌重建。实施了勒福Ⅰ型截骨术并向下植骨，取自体髂骨进行移植以重建严重萎缩的上颌骨。在随后的手术中，植入了上颌和下颌种植体。制作了种植体支持的覆盖义齿以恢复功能和美观。
