To identify the risk of complications (eg, implant loss, infection, peri-implantitis, and mucositis) in a group of patients treated with osseointegrated implants and to assess the effect of smoking on this risk.
A retrospective cohort study of patients treated in the Unit of Implantology, University of Barcelona Faculty of Dentistry was performed. All patients had already undergone prosthetic treatment, and the minimal follow-up time after implant surgery was 6 months.
A total of 295 patients fulfilled the inclusion criteria; 56.9% were women and 43.1% were men. They received a total of 1,033 implants. There were 209 complications (32 cases of implant loss, 2 cases of infection, 70 cases of peri-implantitis, and 105 cases of mucositis). The smoking habit was associated with an increased risk of complications (P = .008).
Smokers had an increased risk of complications, including infection, implant loss, mucositis, and peri-implantitis, compared with nonsmoking patients.
确定接受骨整合种植体治疗的一组患者发生并发症（如种植体丢失、感染、种植体周围炎和黏膜炎）的风险，并评估吸烟对该风险的影响。
对巴塞罗那大学牙科学院种植科治疗的患者进行回顾性队列研究。所有患者均已接受修复治疗，种植手术后的最短随访时间为6个月。
共有295例患者符合纳入标准；56.9%为女性，43.1%为男性。他们共接受了1033颗种植体。发生了209例并发症（32例种植体丢失、2例感染、70例种植体周围炎和105例黏膜炎）。吸烟习惯与并发症风险增加相关（P = 0.008）。
与不吸烟患者相比，吸烟者发生包括感染、种植体丢失、黏膜炎和种植体周围炎在内的并发症的风险增加。
