Abstract：
This report of cases aims to share our treatment experiences in 4 sinus graft infection cases after sinus floor elevation and simultaneous implant placement. The preoperative and postoperative intraoral and radiographic photographs were collected and used to assess the treatment outcomes. The sinus cavity status, bone augmentation results, and implant stability were used as measurements to determine the treatment effectiveness. Four patients received partial graft removal as their surgical treatment for sinus graft infection combined with antibiotic therapy, with or without immediate secondary grafting. After early intervention, antibiotic therapy, and partial debridement of the infected sinus grafts, radiographic and clinical outcomes indicate successful resolution of the graft infection and stable bone graft levels around the implants. The keys to the successful management of the sinus graft infection were: early detection of the infection; early intervention, including partial debridement of the infected graft particles; and antibiotic therapy.
摘要：
本病例报告旨在分享我们在窦底抬高和同时放置植入物后的四例鼻窦移植物感染病例中的治疗经验。收集术前和术后的口腔内和影像学照片，并用于评估治疗结果。窦腔状态,骨增强结果，和植入物稳定性被用作确定治疗有效性的测量。4例患者接受了部分移植物切除手术治疗，以治疗鼻窦移植物感染并结合抗生素治疗。有或没有立即二次嫁接。早期干预后,抗生素治疗,以及感染的鼻窦移植物的部分清创术，影像学和临床结果表明移植物感染成功解决，植入物周围的植骨水平稳定。成功治疗鼻窦移植物感染的关键是：早期发现感染；早期干预，包括感染的移植物颗粒的部分清创术；和抗生素治疗。
