Maxillary sinus grafting is generally a safe procedure. However, intraoperative complications, as well as early and late postoperative complications, may occur. Included in the latter group are graft infections that can be triggered by peri-implantitis. The aim of the present study was to report three cases of late maxillary sinus graft infections and to histologically evaluate the effects of peri-implantitis in the grafted area. In peri-implantitis cases in grafted sinuses, the sole removal of the implant along with accompanying debridement of the infected area may not be sufficient to resolve the infection, and a more-aggressive treatment may be necessary.
上颌窦植骨术通常是一种安全的手术。然而，术中并发症以及早期和晚期术后并发症都可能发生。后者包括可由种植体周围炎引发的移植物感染。本研究的目的是报告三例晚期上颌窦移植物感染，并对移植区种植体周围炎的影响进行组织学评估。在移植窦中的种植体周围炎病例中，仅仅去除种植体并伴随感染区域的清创可能不足以解决感染，可能需要更积极的治疗。
