The aim of this study was to evaluate clinical and radiological outcomes of the unsplinted implants supporting mandibular overdenture when applying conventional or early loading protocols.
Twenty-six edentulous patients were treated with two unsplinted Brånemark System implants supporting mandibular overdenture. There was a test group, in which the overdenture was connected 1 week after surgery, and a control group, in which the overdenture was connected 3 months after surgery. Peri-implant parameters were recorded 1, 6, and 12 months after surgery. Clinical stability measurements were performed at surgery, and after 3, 6, and 12 months. Marginal bone levels were evaluated at implant surgery, after 6, and after 12 months.
No implant from either group was lost. Clinical peri-implant parameters, clinical stability measurements, and marginal bone resorptions showed no statistically significant differences between two groups during 12 months.
The results of this study suggest that one-week of early loading protocol of two Brånemark implants supporting mandibular overdenture does not compromise implant stability, marginal bone loss, and peri-implant soft-tissue health.
本研究旨在评估采用传统或早期加载方案时,无夹板种植体支持下颌覆盖义齿的临床和放射学结果。
26例无牙颌患者接受了两枚无夹板的Brånemark系统种植体支持下颌覆盖义齿的治疗。有一个试验组,其中覆盖义齿在术后1周连接,还有一个对照组,其中覆盖义齿在术后3个月连接。在术后1、6和12个月记录种植体周围参数。在手术时以及术后3、6和12个月进行临床稳定性测量。在种植手术时、术后6个月和12个月评估边缘骨水平。
两组均无种植体丢失。在12个月期间,两组的种植体周围临床参数、临床稳定性测量和边缘骨吸收均无统计学显著差异。
本研究结果表明,两枚Brånemark种植体支持下颌覆盖义齿的一周早期加载方案不会损害种植体稳定性、边缘骨丢失和种植体周围软组织健康。
