Int J Implant Dent:磨牙区即刻修复的一年结局

2020-02-16 不详 网络

越来越多的人选择牙缺失后行即刻种植修复。这项前瞻性病例系列试验研究旨在评估在1年的随访期内缺失后牙行即刻种植修复的结果。研究纳入了15例患者,这些患者的上颌或下颌有单个磨牙缺失,并有足够的骨量满足植体稳定性和避免感染的发生。按照两阶段的手术程序,将具有大螺纹深度和锋利螺纹边缘的植入物放置在每个患者颌骨内。三个月后,提供了一个全轮廓的,螺丝固定的氧化锆修复体,带有倾斜的螺丝通道基台。放置修复体后1个

越来越多的人选择牙缺失后行即刻种植修复。这项前瞻性病例系列试验研究旨在评估在1年的随访期内缺失后牙行即刻种植修复的结果。

研究纳入了15例患者,这些患者的上颌或下颌有单个磨牙缺失,并有足够的骨量满足植体稳定性和避免感染的发生。按照两阶段的手术程序,将具有大螺纹深度和锋利螺纹边缘的植入物放置在每个患者颌骨内。三个月后,提供了一个全轮廓的,螺丝固定的氧化锆修复体,带有倾斜的螺丝通道基台。放置修复体后1个月和12个月,进行了临床和射线照相检查。此外,患者对修复的满意度在12个月后评分。

结果显示,在进行1年评估之前,必须移除15颗植体中松动的4颗。在一年的评估中,植入和修复的存活率为73.3%(n = 15)。从负荷到随访12个月的平均边缘骨丢失量为0.17mm(n = 11)。平均菌斑,牙结石,种植体周围粘膜,出血和口袋探查深度得分较低,表明健康的种植体周围状况。患者满意度非常高。

综上所述,在本研究的限制范围内,我们发现将常规直径的植体即刻植入颌骨磨牙区部位在一年的随访期内出现较高的植入失败率。
