This study retrospectively evaluated the effect of soft tissue condition on peri-implant health. Clinical variables (Plaque Index, keratinized tissue width, gingival biotype, and vestibular depth) were recorded. Probing depth, soft tissue recession, bleeding on probing, and radiographic marginal bone loss were assessed in relation to independent variables. Statistical analysis was performed using Mann-Whitney U test or Kruskal-Wallis rank test and a logistic regression model at the implant level. A total of 139 implants in 43 patients were assessed. Bleeding on probing was recorded at 54.7% sites, which was significantly related to the biofilm accumulation. Gender, history of periodontal disease, patient adherence to recall visits, and the presence of plaque were associated with higher peri-implant probing-depth values. The maximum soft tissue recession was recorded at sites with a thin biotype and shallow vestibular depth (P = .0). The logistic regression analysis revealed that plaque (P = .002) and vestibular depth (P = .043) were significantly associated with peri-implantitis. Within the study limitations, patients with high plaque accumulation and shallow vestibular depth are more prone to peri-implant disease.
本研究回顾性评估了软组织状况对种植体周围健康的影响。记录了临床变量（菌斑指数、角化组织宽度、牙龈生物型和前庭深度）。评估了探诊深度、软组织退缩、探诊出血和放射状边缘骨丧失与独立变量的关系。使用曼-惠特尼 U 检验或克鲁斯卡尔-沃利斯秩检验和逻辑回归模型在种植体水平上进行统计分析。共评估了 43 名患者的 139 个种植体。54.7%的位点记录到探诊出血，这与生物膜积聚显著相关。性别、牙周病史、患者对复诊的依从性以及菌斑的存在与较高的种植体探诊深度值相关。最大的软组织退缩发生在生物型较薄和前庭深度较浅的部位（P=.0）。逻辑回归分析显示，菌斑（P=.002）和前庭深度（P=.043）与种植体周围炎显著相关。在研究的局限性内，菌斑堆积较多和前庭深度较浅的患者更容易发生种植体周围疾病。
