This study aims to investigate the underlying causes of dental implant failure, focusing on implant-related complications and associated risk factors. Understanding these factors will help improve treatment planning and enhance implant success rates. A retrospective case-control study was conducted using clinical, medical, surgical, and radiographic records of patients who underwent dental implant removal due to complications. Key factors analyzed included patient-related variables (age, gender, medical conditions, periodontal disease), implant-related factors (implant site, implant system, restoration status), and procedural aspects (previous surgical interventions and reasons for implant removal). The findings revealed that implant type ( = 0.004) and type of restoration ( = 0.001) significantly influenced implant survival. Gender ( = 0.001), medical conditions, smoking status ( = 0.004), and restoration status ( = 0.005) were significantly associated with specific failure mechanisms. Lack of osseointegration (36.4%) and absence of primary stability (22.4%) were the predominant causes of implant failure. Prior surgical interventions ( = 0.001) and decisions for re-implantation ( = 0.005) significantly affected implant removal frequency. Implant survival is influenced by multiple factors, with implant type, restoration type, and gender playing key roles in failure outcomes. Patient-specific risk assessment, particularly regarding medical conditions and smoking, meticulous surgical technique, and appropriate prosthetic planning, is vital for improving implant longevity and minimizing failure rates.
本研究旨在调查牙种植体失败的潜在原因，重点关注种植体相关并发症及相关风险因素。了解这些因素将有助于改进治疗方案规划并提高种植成功率。我们进行了一项回顾性病例对照研究，使用因并发症而接受牙种植体取出的患者的临床、医学、外科和影像学记录。分析的关键因素包括患者相关变量（年龄、性别、健康状况、牙周疾病）、种植体相关因素（种植部位、种植系统、修复状态）以及手术操作方面（既往手术干预及种植体取出原因）。研究结果显示，种植体类型（=0.004）和修复类型（=0.001）对种植体存留率有显著影响。性别（=0.001）、健康状况、吸烟状况（=0.004）以及修复状态（=0.005）与特定的失败机制显著相关。骨结合缺失（36.4%）和初始稳定性缺乏（22.4%）是种植体失败的主要原因。既往手术干预（=0.001）和再次种植的决策（=0.005）对种植体取出频率有显著影响。种植体存留率受多种因素影响，其中种植体类型、修复类型和性别在失败结果中起关键作用。针对患者的风险评估，尤其是关于健康状况和吸烟情况的评估、细致的手术技术以及恰当的修复计划，对于提高种植体使用寿命和降低失败率至关重要。
