Int J Oral Max Surg:下颌骨后部短种植体与长种植体的比较

2017-11-19 MedSci MedSci原创

这项回顾性研究比较了支持下颌骨后部局部固定义齿的短种植体(6 mm)(短组)和植入在自体骨块垂直植骨后的5 mm标准长度种植体(≥9 mm)(植骨组)后5年的临床和影像学结果

这项回顾性研究比较了支持下颌骨后部局部固定义齿的短种植体(6 mm)(短组)和植入在自体骨块垂直植骨后的5 mm标准长度种植体(≥9 mm)(植骨组)后5年的临床和影像学结果。 45名牙列缺损患者入选本研究,5年后进行评估:植骨组22例(51个种植体),短组23例(短种植体46例)。植骨组有8例发生了手术并发症,而短组无(P = 0.003)。4年后由于种植体周围炎,1例短种植体和1例标准长度的种植体在受力前失败(P = 1.0)。植骨组出现8例生物学和2例义齿并发症,短组3例生物学和3例义齿并发症(发生率分别为P = 0.09和P = 1.0)。植骨组平均边缘骨吸收为1.61±1.12mm,短组为0.68±0.68mm(P = 0.002)。在本研究的局限,这两种技术在5年后的临床结果都取得了成功,但短种植体与植骨组的标准长度种植体相比,手术并发症和边缘性骨吸收较少。
