To report the prevalence of peri-implant diseases in a North African patient population, and to assess the concurrent associations of patient- and implant-level characteristics with probing depth and bone loss around dental implants METHODS: A total of 642 implants in 145 subjects were followed up for a mean 6.4 years. At the last follow-up visit the subjects were examined clinically and radiographically to assess the status of peri-implant tissues and teeth. Data analysis used the generalized linear mixed models RESULTS: The prevalence of peri-implant mucositis and peri-implantitis were 82.1% and 41.4% at the subject level, and 68.4% and 22.7% at the implant level, respectively. Inadequate plaque control, peri-implant inflammation, history of previous implant failures, and pain/discomfort at the implant site were significantly associated with both outcomes (increased probing depth and bone loss). Diabetes mellitus, inadequate implant restoration, single restorations (versus multi-unit), cement-retained restorations, and presence of occlusal wear facets on teeth were significantly associated with one of the two outcomes. Implants placed in the lower anterior jaw region had the most favorable outcome. Smoking, history of periodontitis, and type of implant surface did not show significant associations with higher frequency of peri-implant diseases in the multivariable analysis.
Peri-implant diseases are prevalent in this North African patient population. Multiple subject- and implant-level variables were associated with peri-implant diseases. Risk assessment of these effects should consist of a concurrent inclusion of these factors in multivariable analyses that also adjust for the complex variance structure of the oral environment.
报告北非患者人群中种植体周围疾病的流行情况，并评估患者和种植体水平特征与种植体周围组织的探诊深度和骨丧失之间的并发关联。
对 145 名受试者的 642 个种植体进行了平均 6.4 年的随访。在最后一次随访时，对受试者进行了临床和影像学检查，以评估种植体周围组织和牙齿的状况。数据分析采用广义线性混合模型。
种植体周围黏膜炎和种植体周围炎在受试者水平的患病率分别为 82.1%和 41.4%，在种植体水平的患病率分别为 68.4%和 22.7%。菌斑控制不当、种植体周围炎症、既往种植体失败史以及种植体部位的疼痛/不适与两种结果（探诊深度增加和骨丧失）显著相关。糖尿病、种植体修复不当、单牙修复（与多单位修复相比）、黏结固位修复体以及牙齿存在咬合面磨损面与其中一种结果显著相关。在下颌前牙区植入的种植体具有最佳的预后。在多变量分析中，吸烟史、牙周病史和种植体表面类型与种植体周围疾病的高发生率无显著相关性。
种植体周围疾病在北非患者人群中很常见。多个患者和种植体水平的变量与种植体周围疾病相关。这些影响的风险评估应包括将这些因素同时纳入多变量分析中，同时调整口腔环境的复杂方差结构。
