3557例种植患者种植体周围炎的回顾性研究

Peri-implantitis: A retrospective study of 3 557 patients

目的:总结并分析种植体周围炎发病率及其相关性因素。方法:纳入3 557例种植修复病例,总结种植患者各项指标。结果:共使用9种种植体系统6 223枚种植体,种植体周围炎发病率患者8. 4%,种植体水平7. 6%,修复后5年以上发病率11. 3%。Straumann系统最低(3. 1%)。上前牙区(9. 3%)周围炎发生率明显大于其他区域。不同附加手术周围炎发生率不存在统计学差异。愈合时间段3～6个月(10. 2%)周围炎发生率明显大于6～9个月和9～12个月。冠边缘不密合(78. 9%)发生后的种植体周围炎发生率最高。94. 8%种植体周围炎经治疗得到控制,5. 4%失败。结论:种植体周围炎发病率同修复性因素、种植系统、愈合时间及种植牙位相关。

Objective:To analyze the incidence of peri-implantitis and its related factors.Methods:3 557 patients underwent dental implant treatment,the data were summarized and retrospectively analyzed.Results:9 implant systems including 6 223 implants were used,the incidence of peri-implantitis was 8.4%of all cases and 7.6%of all implants.The incidence of early infection was 2.5%.The lowerst incidence of peri-implantitis was 3.1%in the Straumann system.The incidence of periarthritis of upper anterior region(9.3%)was significantly higher than that of other regions.There was no statistical difference in the incidence of peri-implantitis among the different surgical procedures.The incidence of peri-implantitis was significantly longer in the healing period of 3-6 months(10.2%)than in 6-9 and 9-12 months.Uncorrected margins produced the most cases of peri-implantitis among all the complications(78.9%).5.4%of implants with periarthritis failed,94.8%were controlled after treatment.Conclusion:The incidence of peri-implantitis was associated with restorative factors,implant system,healing time and tooth position.
