The goals of this research were to determine the influence of several factors on implants' biological and technical complications in posterior fixed implant prosthetic therapy.
The study group consisted of 67 edentulous patients (mean age: 63.88 ± 11.709 yrs; 20 males, 47 females) with implant prosthetic therapy for posterior edentulism. A total of 76 implant-supported fixed partial dentures (IP-FPDs) and 178 implants were assessed using clinical and paraclinical assessments. Risk factors for biological complications (peri-implantitis) and technical complications were determined by using the Pearson Chi-squared test and multivariate analysis.
The implant success (the absence of biological and mechanical/technical complications) was 66.30%. The prevalence of biological complications was 13.5%. The prevalence of technical complications was 28.70%. Variables that were associated with a higher risk of peri-implantitis were poor oral hygiene and bruxism. In univariate analysis, poor oral hygiene increased the risk of peri-implantitis 5.778 times and bruxism 5.875 times. Variables that were associated with a higher risk of mechanical/technical complications were age group > 60 yrs, smoking, history of periodontal disease, and bruxism. In univariate analysis, the risk of technical complications increased 4.14 times for patients in the age group > 60 years (vs. age group 40-60 years) and 20.5 times for patients with bruxism. Bruxism and smoking were significant predictors of mechanical/technical complications in the multivariate model.
In univariate models, patients with poor oral hygiene and bruxism have an increased risk of peri-implantitis. In multivariate models, we did not identify significant predictors of peri-implantitis. Age group > 60 yrs, smoking, history of periodontal disease, bone grafting, and bruxism are risk factors for the increase in the mechanical/technical complication rate. In the multivariate model, smoking and bruxism are significant predictors of the mechanical/technical complications.
本研究的目的是确定多种因素对后牙固定种植修复治疗中种植体生物及技术并发症的影响。
研究组由67例无牙患者（平均年龄：63.88±11.709岁；男性20例，女性47例）组成，均接受了后牙无牙颌的种植修复治疗。通过临床和辅助临床评估对总共76例种植支持的固定局部义齿（IP-FPD）和178颗种植体进行了评估。使用Pearson卡方检验和多变量分析确定生物并发症（种植体周围炎）和技术并发症的危险因素。
种植体成功率（无生物及机械/技术并发症）为66.30%。生物并发症的发生率为13.5%。技术并发症的发生率为28.70%。与种植体周围炎风险较高相关的变量是口腔卫生差和磨牙症。在单变量分析中，口腔卫生差使种植体周围炎风险增加5.778倍，磨牙症使风险增加5.875倍。与机械/技术并发症风险较高相关的变量是年龄>60岁、吸烟、牙周病史和磨牙症。在单变量分析中，年龄>60岁的患者（与40-60岁年龄组相比）技术并发症风险增加4.14倍，磨牙症患者增加20.5倍。在多变量模型中，磨牙症和吸烟是机械/技术并发症的显著预测因素。
在单变量模型中，口腔卫生差和磨牙症患者发生种植体周围炎的风险增加。在多变量模型中，我们未确定种植体周围炎的显著预测因素。年龄>60岁、吸烟、牙周病史、骨移植和磨牙症是机械/技术并发症发生率增加的危险因素。在多变量模型中，吸烟和磨牙症是机械/技术并发症的显著预测因素。
