种植体早期失败相关因素的临床回顾性分析研究

摘要/Abstract

摘要： 目的回顾性分析大样本数据下口腔种植早期失败的影响因素。方法搜集浙江大学医学院附属口腔医院2011年—2015年内8 852例患者资料，共15 204颗种植体，其中男4 413例，女4 439例，Straumann种植体11 899颗，Nobel种植体1 993颗，Ankylos种植体1 312颗，绘制表格分析资料，并用卡方检验从性别、年龄、种植区位置、种植体尺寸、系统和骨增量手术这几个方面分析口腔种植早期失败的影响因素。结果 5年内早期失败83例、97颗种植体，种植体早期失败率为0.64%。2013年以后种植体早期失败率逐年降低，种植体系统之间早期失败率无统计学差异。男性患者种植体早期失败率明显高于女性患者，≥61岁的患者比41～60岁和 ≤40岁的患者的早期失败率都高，且有统计学差异。下颌前牙区植入数最少，种植体早期失败率明显比其他区域高。细种植体(≤3.5 mm)比常规种植体和粗种植体失败率高，长种植体(＞13 mm)的早期失败率明显较低。结论老年男性患者更容易发生种植体早期失败，细种植体、短种植体和下颌前牙区的种植体失败率更高。

Abstract: Objective To retrospectively analyze risk factors which influence early implant failure under a large sample data. Methods A total of 8 852 patients with 15 204 dental implants were collected from The Affiliated Stomatology Hospital, School of Medicine, Zhejiang University during the years of 2011-2015, which included 4 413 males and 4 439 females, 11 899 Straumann group implants, 1 993 Nobel group implants and 1 312 Ankylos group implants. Age, gender, location, implant brands, implant size and bone augmentation procedures were recorded. Chi square test was used to identify risk factors associated with early implant failure. Results Ninetyseven implants in 83 patients failed before or at the provisional restorations, and the 5year early implant failure rate was 0.64%. After 2013, the early failure rate of implants decreased year by year, and there was no significant difference between the early failure rates of implant systems. The early failure rate of male patients was significantly higher than that of female patients, and the failure rate of patients over 61 was significantly higher than that of patients within 41~60 and below 40 . The number of implants in mandibular anterior area was the smallest, while the failure rate of implant was significantly higher than that in other areas. The failure rate of narrowdiameter implant (≤3.5 mm) was higher than that of regulardiameter and widediameter implant, while the early failure rate of long implant (>13 mm) was significantly lower than the other two lengths of implants. Conclusions Elderly male patients are more likely to develop early implant failure. The early failure rates of narrowdiameter implants, short implants and implants at the mandibular anterior are much higher.
