To evaluate early implant failure rate of implants placed by maxillofacial-oral surgeons and periodontists.
A nested case-case study was performed to analyze treatment outcome of 27 oral surgeons and 30 periodontists who performed at least 100 dental implants between 2017 and 2019 in 54 clinics of "Maccabi-Dent," a nation-wide dental chain. A total of 26,865 implants were evaluated.
The early failure rate of 1.3% achieved by the periodontists was lower than the 1.7% early failure rate achieved by oral surgeons. Differences were not statistically different. Oral surgeons in the study cohort were insignificantly older in age, with more years of experience as dentists and as specialists. However, the only parameter found to be a predictor to early implant failure in a linear regression model was related to postgraduate training. Explicitly, the mean number of implants placed during specialty program. This number was higher for the periodontists and found to be significantly contributing predictor to early implant failure. Clinicians' age and years of experience as dentists or as specialist were not found to be predictors to early implant failure rate.
No statistically significant differences were found in early implant failure rate between oral surgeons and periodontists. The number of implants placed during specialty program has a statistical predictive value to early implant failure rate.
Care and attention should be taken to re-evaluate clinical training in the field of implantology during specialty program. To optimize surgeons' control on treatment outcome.
评估颌面口腔外科医生和牙周病医生植入物的早期失败率。
进行了一项嵌套病例对照研究，以分析 2017 年至 2019 年间在“Maccabi-Dent”全国性牙科连锁的 54 家诊所中至少进行了 100 例种植牙的 27 名口腔外科医生和 30 名牙周病医生的治疗结果。共评估了 26865 例种植体。
牙周病医生 1.3%的早期失败率低于口腔外科医生 1.7%的早期失败率。差异无统计学意义。研究队列中的口腔外科医生年龄稍大，作为牙医和专家的经验也更多。然而，线性回归模型中唯一被发现是早期种植体失败的预测因素与研究生培训有关。具体来说，就是在专业课程中放置的种植体数量。牙周病医生的这一数字更高，并且被发现是早期种植体失败的显著预测因素。临床医生的年龄和作为牙医或专家的经验年限都不是早期种植体失败率的预测因素。
口腔外科医生和牙周病医生之间的早期种植体失败率没有统计学上的显著差异。专业课程中放置的种植体数量对早期种植体失败率具有统计学预测价值。
在专业课程中，应注意重新评估种植牙领域的临床培训。以优化外科医生对治疗结果的控制。
