J Dent Res:骨质疏松症/骨质疏松症妇女种植治疗的临床结果与健康者相似

2019-03-24 不详 网络

骨质疏松症对种植体治疗的影响仍然存在争议,因为它可能导致更高的失败率。由于缺少长期对照试验,本研究旨在验证植入全身性骨质疏松症患者的植入物的长期结果。使用双X射线吸收测量扫描,对需要植入物的绝经后妇女进行髋部和脊柱骨密度测量。根据T评分,将它们分为2组:O组(骨质疏松组),T评分≤-2或C组(对照组),T评分≥-1。植入物以2阶段方式放置并在放置基台后4至8周加载。装载后6个月,此后每年评估临床和

骨质疏松症对种植体治疗的影响仍然存在争议,因为它可能导致更高的失败率。由于缺少长期对照试验,本研究旨在验证植入全身性骨质疏松症患者的植入物的长期结果。

使用双X射线吸收测量扫描,对需要植入物的绝经后妇女进行髋部和脊柱骨密度测量。根据T评分,将它们分为2组:O组(骨质疏松组),T评分≤-2或C组(对照组),T评分≥-1。植入物以2阶段方式放置并在放置基台后4至8周加载。装载后6个月,此后每年评估临床和放射学参数。

总共有148名患者植入了148颗植体(平均年龄:67岁[范围59-83])。在20名患者(O组)中植入63颗植体,在28名患者(C组)中植入85颗植体。5年后,评估37名患者中的117颗植体(O组38个,C组79个)。种植体水平的累积存活率为96.5%(O组:91.5%; C组:100.0%[P <0.05]),病人水平为95.7%(O组:89.2%; C组:100.0%[P> 0.05])。加载5年后,在种植体水平整体边缘骨水平改变为-0.09±0.78 mm(组O:-0.15±0.50 mm;组C:-0.06±0.89 mm),患者水平为-0.09±0.54 mm(组O:-0.18±0.43mm; C组:0.06±0.58mm)(P> 0.05)。

总之,该研究结果表明,骨质疏松症患者的口腔种植治疗是一种可靠的治疗选择,骨整合率、植入物存活率和5年功能负荷后的边缘骨水平改变与健康者相当。
