The aim of this study was to evaluate the success of one-stage implants placed at the time of alveolar bone augmentation using simultaneous guided bone regeneration technique with a collagen barrier membrane in patients suffering from insufficient bone width. Seventeen patients were treated with 20 one-stage OSTEOFIX (Oulu, Finland) implants using simultaneous guided bone regeneration technique. Dehiscence defects were filled by bovine bone mineral Bio-Oss and covered with collagen membrane. Clinical and radiographic parameters of the peri-implant conditions were assessed at the moment of prosthesis placement and at 1- and 5-year follow-ups. Diagnostic dehiscence defect measurements after implant placement showed that the mean vertical defect varied from 3.8 mm to 10.0 mm. At the moment of prosthesis placement and at 1- and 5-year follow-ups all implants were stable, painless and without biological complications. Clinical and radiographic parameters of the peri-implant conditions remained stable during follow-up. The cumulative implant survival rate was 100% after the 5-year observation period and the success rate for all pooled implants was 90%. The present study showed predictable treatment outcomes recorded after 5 years of function for one-stage OSTEOFIX (Oulu, Finland) oral implants placed simultaneously with guided bone regeneration using collagen membrane and deproteinized bovine bone mineral.
本研究的目的是评估在骨宽度不足的患者中，使用胶原屏障膜通过同步引导骨再生技术在牙槽骨增量时同期植入的一期种植体的成功率。17例患者采用同步引导骨再生技术植入了20枚一期OSTEOFIX（芬兰奥卢）种植体。骨裂开缺损用牛骨矿物质Bio-Oss填充，并用胶原膜覆盖。在义齿植入时以及1年和5年随访时评估种植体周围状况的临床和影像学参数。种植体植入后诊断性骨裂开缺损测量显示，平均垂直缺损在3.8毫米至10.0毫米之间。在义齿植入时以及1年和5年随访时，所有种植体均稳定、无痛且无生物学并发症。随访期间种植体周围状况的临床和影像学参数保持稳定。5年观察期后种植体累计存留率为100%，所有汇总种植体的成功率为90%。本研究显示，使用胶原膜和脱蛋白牛骨矿物质同步引导骨再生同期植入的一期OSTEOFIX（芬兰奥卢）口腔种植体在功能5年后记录的治疗结果具有可预测性。
