Abstract

Introduction

Dental implant treatment can still fail due to various factors. The aim of this retrospective cohort study was to assess the influence of operator experience in a postgraduate educational setting, as well as patient, implant, and surgical risk factors on the incidence of the dental implant failure.

Methods

The dental records of 1049 implants with a mean follow-up of 794.70 days were analysed. Variables included operator experience (year of specialty study) and clinic-pathological patients’ related variables. Clinic-pathological associations were explored and a Cox regression model accounted for implant survival factors.

Results

Multivariate analysis revealed that a history of periodontitis and smoking were the only factors with independent prognostic value, with hazard ratios of 2.0 (95 % CI: 1.0–4.0, p = 0.048) and 1.9 (95 % CI: 1.0–3.6, p = 0.039) respectively. Conversely, despite implant treatment delivered by early career students had a higher failure rate (5.6 %) compared to advanced career students (3.7 %), this difference was statistically significant only in the univariate analysis.

Conclusion

Periodontitis and smoking are independent prognostic variables, with career level potentially biasing complex case allocation to advanced students. Targeted educational interventions, including virtual reality and artificial intelligence, should be emphasized in student training. University-based implant trials must consider operator career stage.

Clinical significance

The study underscores the importance of operator experience in dental implant success. It highlights that while clinical experience influences outcomes, factors like a history of periodontitis and smoking are independent predictors of implant failure. These findings emphasize the need for targeted educational interventions to improve clinical training and patient outcomes.

在研究生教育环境中植入牙科植入体的存活率：一项回顾性队列研究。

引言种植牙治疗仍有可能因各种因素而失败。这项回顾性队列研究旨在评估研究生教育环境中操作者的经验以及患者、种植体和手术风险因素对种植牙失败发生率的影响：分析了 1049 个种植体的牙科记录，平均随访时间为 794.70 天。变量包括操作者的经验（专业学习年份）和临床病理患者的相关变量。结果显示，多变量分析表明，有种植体植入史的患者在种植体植入后存活率较高，而无种植体植入史的患者存活率较低：多变量分析显示，牙周炎病史和吸烟是唯一具有独立预后价值的因素，危险比分别为 2.0（95% CI：1.0-4.0，p=0.048）和 1.9（95% CI：1.0-3.6，p=0.039）。相反，尽管早期职业学生的种植治疗失败率（5.6%）高于晚期职业学生（3.7%），但这一差异仅在单变量分析中具有统计学意义：结论：牙周炎和吸烟是独立的预后变量，职业水平可能导致复杂病例分配偏向于高年级学生。在学生培训中应强调有针对性的教育干预，包括虚拟现实和人工智能。大学种植试验必须考虑操作者的职业阶段：这项研究强调了操作者的经验对种植牙成功的重要性。临床意义：该研究强调了操作者经验对种植牙成功的重要性，并着重指出，虽然临床经验会影响种植结果，但牙周炎病史和吸烟等因素是种植失败的独立预测因素。这些发现强调了有必要采取有针对性的教育干预措施，以改善临床培训和患者预后。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
