Long-term follow-up of oral implant therapy seldom report all biological and technical complications. The objective of this study was to evaluate the long-term (9-15 years) outcome after dental implant therapy, assess survival and complication rates. In addition, to identify the risk indicators of these complications at patient and implant levels. Patients (n = 376) treated with dental implants (n = 1095) between 1999 and 2005 at a specialist clinic in Stockholm, Sweden, were included. Longitudinal data were collected retrospectively from digital dental records. A subset of the included patient underwent a clinical examination at the 9-15 years follow-up (n = 163). Chi-square tests, Kaplan-Meier analyses and the general estimating equations (GEE) procedure were adopted for multilevel analyses. The cumulative implant survival rate up to 15 years was 82.6% (SE 4.1%). The prevalences of biological and technical complications at patient level were 52% and 32%, respectively. In total, 763 complications occurred, 65% of patients experienced at least one complications. Implant loss occurred significantly more frequently in subjects with a history of treated severe periodontitis Stage III-IV (P = .008) and in cases when complications were registered during implant surgery (P = .010). Smoking was a significant risk indicator for peri-implantitis (P = .006). The long-term implant survival and complication rates at patient level were 83% and 79%, respectively. Implant loss was significantly more frequent for subjects with a history of treated severe periodontitis and if complication was registered during implant surgery. Smoking was a significant risk indicator for peri-implantitis.
长期随访的口腔种植治疗很少报告所有的生物学和技术并发症。本研究的目的是评估牙种植治疗的长期（9-15 年）结果，评估生存率和并发症发生率。此外，还确定了患者和种植体水平上这些并发症的风险指标。在瑞典斯德哥尔摩的一家专科诊所，对 1999 年至 2005 年间接受牙种植治疗的患者（n=376）和植入物（n=1095）进行了长期随访。从数字牙科记录中回顾性收集纵向数据。在 9-15 年的随访中，对包括的患者亚组进行了临床检查（n=163）。采用卡方检验、Kaplan-Meier 分析和广义估计方程（GEE）程序进行多水平分析。15 年时种植体的累积存活率为 82.6%（SE 4.1%）。患者水平上生物学和技术并发症的患病率分别为 52%和 32%。共发生 763 例并发症，65%的患者至少发生过一次并发症。有治疗过的严重牙周炎 III-IV 期病史的患者（P=.008）和在种植手术期间发生并发症的患者（P=.010），种植体丢失的发生率显著更高。吸烟是发生种植体周围炎的显著危险因素（P=.006）。患者水平上的长期种植体生存率和并发症发生率分别为 83%和 79%。有治疗过的严重牙周炎病史和种植手术期间发生并发症的患者，种植体丢失的发生率显著更高。吸烟是发生种植体周围炎的显著危险因素。
