Clin Implant Dent Relat Res:种植失败有何原因?我国大样本研究告诉你~

南京大学医学院的一项研究显示,性别、种植体长度和种植体植入位置被认为是种植失败的潜在危险因素。该论文11月19日在线发表于《临床种植牙科相关研究》(Clin Implant Dent Relat Res)杂志。


南京大学医学院的一项研究显示,性别、种植体长度和种植体植入位置被认为是种植失败的潜在危险因素。该论文11月19日在线发表于《临床种植牙科相关研究》(Clin Implant Dent Relat Res)杂志。

该研究目的是评估与种植失败相关的危险因素,尤其是上颌磨牙位置。2015年1月至2017年3 月,共4338 例患者在南京口腔医院植入了6977例种植体,研究者记录了有关患者年龄、性别、植骨手术、种植体位置、长度、直径以及丢失种植体情况的信息。使用生存曲线方法和对数秩检验进行生存函数分析。运用卡方检验和多变量Cox回归分析来确定与种植失败相关的风险因素。

结果为,所有种植体观察0~32个月后的累积留存率为97.76%,位于上颌磨牙处的种植体留存率为97%。研究显示与其他种植体相比,位于上颌磨牙处的种植体留存率更低(P <0.05)。患者性别为男性和种植体长度过短(<10 mm)被认为是种植失败的危险因素。然而,患者性别和是否进行过植骨手术被认为是引起上颌磨牙处种植失败的危险因素。
