Risk indicators of peri-implantitis is still contradictory and somehow unclear in present literature therefore efforts should be done for better understanding of the exact etiology of peri-implant disease progression. The present study aimed to assess risk indicators associated with peri-implantitis by observing the changes in several periodontal parameters after implant placement. This cross-sectional study included 213 female and 271 male patients aged 26-87 years, who received 484 titanium implants (Straumann, Switzerland) at King Saud University's Dental College, Saudi Arabia. Patients were called for dental visits. During these visits; full clinical and radiographic assessment of implants were done. The periodontal pocket depth (PPD) was greater around implants placed at grafted sites than non-grafted sites and around bone-level implants than tissue-level implants. The plaque index (PI) was associated with poor oral hygiene. There was a strong association between graft (yes/no) and bleeding on probing (BOP). Patients with good oral hygiene showed high radiographic bone stability. Keratinized tissue width < 2 mm was associated with a higher PPD, higher PI, higher BOP, more edematous gingiva, and more exposed implant threads on radiography. In patients receiving implants, poor oral hygiene status and inadequate keratinized tissue level can be proposed as risk indicators for developing periimplantitis due to strong association found between them and developments of peri-implantitis.
种植体周围炎的风险指标在现有文献中仍然存在矛盾和不明确之处，因此应该努力更好地了解种植体周围疾病进展的确切病因。本研究旨在通过观察种植体放置后几个牙周参数的变化来评估与种植体周围炎相关的风险指标。这项横断面研究包括来自沙特阿拉伯沙特国王大学牙科学院的 213 名女性和 271 名男性患者，年龄在 26-87 岁之间，共植入 484 枚钛种植体（Straumann，瑞士）。患者被召集进行牙科就诊。在这些就诊期间，对种植体进行了全面的临床和放射学评估。与非移植部位相比，移植部位周围的种植体牙周袋深度（PPD）更大，与骨水平种植体相比，软组织水平种植体的 PPD 更大。菌斑指数（PI）与口腔卫生不良有关。种植体（是/否）与探诊出血（BOP）之间存在很强的关联。口腔卫生良好的患者显示出较高的放射学骨稳定性。角化组织宽度 < 2mm 与较高的 PPD、较高的 PI、较高的 BOP、水肿的牙龈和放射学上更多暴露的种植体螺纹有关。在接受种植体治疗的患者中，由于发现口腔卫生不良状况和角化组织水平不足与种植体周围炎的发展之间存在很强的关联，因此可以将其作为发生种植体周围炎的风险指标。
