摘要:目的 分析探讨锥度固位种植体即刻种植失败原因及可能的影响因素,提高对种植术后的预测性,为减少临床种植失败提供指导意义。方法:收集2016年1月至2020年12月在南昌大学第四附属医院口腔科行即刻种植的患者372例,锥度固位种植体372颗,进行回顾性研究并分析其失败原因。结果:失败8例,共8枚种植体,性别、年龄、种植牙位等基本信息差异无统计学意义(P>0.05),种植体的长度和种植体植入深度的差异具有统计学意义。结论: 锥度固位种植体在即刻种植术后的失败与众多因素有关,其中种植体长度的选择,种植体植入的深度,口腔卫生情况是引起即刻种植失败的主要原因。

[Abstract] Objective To analyze the causes and possible influencing factors of immediate implant failure of taper retensible implants, improve the prediction of postoperative implant failure, and provide guidance for reducing clinical implant failure. METHODS: A total of 372 patients who received immediate implantation in the Department of Stomatology of the Fourth Affiliated Hospital of Nanchang University from January 2016 to December 2020 were collected, with 372 taper retensioned implants. The reasons for the failure were retrospectively analyzed. Results :8 cases with 8 implants failed, and there were no statistically significant differences in gender, age, implant position and other basic information (P > 0.05), but there were statistically significant differences in implant length and implant depth. Conclusion: The failure of taper retainable implants after immediate implantation is related to many factors, among which the choice of implant length, implant depth and oral hygiene are the main reasons for immediate implant failure.

随着医疗水平的逐年提高,牙列缺损后,种植修复成为临床上常用的修复手段之一。1978年 Schulte等首次提出了即刻種植的概念:即在牙齿拔除后的新鲜拔牙窝内即刻植入种植体。即刻种植是目前临床上被广泛接受的一种种植治疗方案,其临床效果也得到肯定。即刻种植的优点在于减少手术次数,减轻患者痛苦,减少患者的就诊次数缩短治疗时间。但其种植过程较为复杂,影响因素较多,种植失败依然存在,因此本研究通过现有的失败病例为研究对象,分析即刻种植失败的相关因素,总结经验,为以后的临床提供一定的理论依据。
