PURPOSE
To analyze the risk factors of biological complications after implant-fixed denture restoration.
METHODS
Seven hundred and twenty-five implants were placed between March 2012 and March 2016. Follow-up period was 5 to 9 years. The implant mucosal index (IMI) and implant marginal bone loss (MBL) were measured at 3 months-1 year, 2-3 years, 4-5 years, 6-7 years and 8-9 years after restoration. The prevalence and risk factors of peri-implantitis and mucositis were analyzed. SPSS 28.0 software package was used to analyze the date.
RESULTS
The implant survival rate of 5 years was 98.7%. The prevalence of mucositis and peri-implantitis were 37.5% and 8.3% at 8 to 9 years. Smoking, periodontitis, narrow diameter, rough neck , anterior location, bone augmentation caused higher prevalence of peri-implantitis or mucositis (P＜0.05).
CONCLUSIONS
Smoking, periodontitis, implant diameter, implant design, implant location and bone augmentation are the risk factors of implant biological complications.
目的
分析种植固定义齿修复后生物学并发症的危险因素。
方法
2012年3月至2016年3月期间共植入725颗种植体。随访期为5至9年。在修复后3个月至1年、2至3年、4至5年、6至7年和8至9年测量种植体黏膜指数（IMI）和种植体边缘骨丢失（MBL）。分析种植体周围炎和黏膜炎的患病率及危险因素。采用SPSS 28.0软件包对数据进行分析。
结果
5年种植体存活率为98.7%。在8至9年时，黏膜炎和种植体周围炎的患病率分别为37.5%和8.3%。吸烟、牙周炎、直径较窄、颈部粗糙、位于前部、骨增量导致种植体周围炎或黏膜炎的患病率较高（P＜0.05）。
结论
吸烟、牙周炎、种植体直径、种植体设计、种植体位置和骨增量是种植体生物学并发症的危险因素。
