To evaluate the thickness of the sinus membrane in contact with implants inserted 10 years before using an augmentation procedure without grafting material, and to identify adverse events correlated with implant protrusion in the sinus.
Osteotome sinus floor elevations were performed without grafting material. The implants (Straumann AG, Basel, Switzerland) were placed simultaneously, all protruded into the sinus. After 10 years, implants were considered viable in the absence of mobility, pain, infection, or continued radiolucency. Sinus health was assessed using cone-beam computed tomography and by the way of a questionnaire in which patients reported symptoms of sinusitis they might have had.
Controlled implants (21 implants, 13 patients) were osseointegrated. The membrane thickness was <2 mm in 11 patients and 2 to 3 mm with flat thickening in 2 patients. No patients exhibited any clinical or radiographic signs of sinusitis.
No sinus complications were observed after 10 years. The initial protrusion of implants into the sinus did not influence long-term sinus health. The maintenance of successful integration is thus the key to avoiding sinus complication.
评估在不使用移植物的情况下，于 10 年前进行骨增量术植入的种植体，在植入后 10 年的时间里，与种植体接触的窦膜厚度，并确定与窦内种植体突出相关的不良事件。
采用骨凿窦底提升术，不使用移植物。同时植入（施特劳曼股份公司，巴塞尔，瑞士）种植体，所有种植体均突入窦内。10 年后，在没有活动度、疼痛、感染或持续放射性透光的情况下，认为种植体是存活的。通过锥形束计算机断层扫描和问卷调查来评估窦健康状况，问卷调查中患者报告了他们可能患有鼻窦炎的症状。
控制组种植体（21 个种植体，13 名患者）均为骨整合。11 名患者的窦膜厚度<2mm，2 名患者的窦膜厚度为 2-3mm 并伴有平坦增厚。没有患者出现任何鼻窦炎的临床或影像学迹象。
10 年后未观察到窦并发症。种植体最初突入窦内并未影响长期窦健康。因此，保持成功的整合是避免窦并发症的关键。
