To investigate and compare the various restorative and prosthetic parameters affecting peri-implant tissues' health following dental implant placement and functional loading.
A total of 484 dental implants (length>6mm, non-turned, 2-3 piece, titanium - Straumann) were evaluated for patients (male=271; female=213). Study variables such as patient's age, gender, implant restoration/crown type, crown retention, and implant crown status were assessed against various periodontal parameters (periodontal pocket depth (PPD), plaque index (PI), bleeding on probing (BOP), gingival color, and crestal bone level). All the data were analyzed using the SPSS software.
Out of all the investigated dental implants, 201 (42%) of the implants investigated presented with BOP > one-site of the peri-implant mucosa (peri-implant mucositis), 115 (23.76%) presented with peri-implant marginal bone loss. PPD value was significantly lower in good crown status (p<0.0001). Majority of the patients with good crown status had no plaque accumulation based on the PI scores (52.7%). Only 35% of the patients whose crown status was good were having BOP when compared with 65% who did not have any BOP recorded. Gingival color (pale pink and red) showed statistically significant association with crown type (porcelain fused to metal v/s all ceramic) (p=0.005). Most of patients with crown status good had no change in their radiographic findings (94%) compared to only 6% who had implant threads exposed (p<0.0001).
Optimal design of Implant prosthetic factors are vital for avoiding the development of peri-implant mucositis/peri-implantitis and must be considered during treatment planning while restoring dental implants.
研究并比较牙种植体植入及功能加载后影响种植体周围组织健康的各种修复和修复参数。
对484颗牙种植体（长度>6mm，非车削，2 - 3件式，钛材质 - 士卓曼）进行评估，患者中男性271例，女性213例。针对各种牙周参数（牙周袋深度（PPD）、菌斑指数（PI）、探诊出血（BOP）、牙龈颜色和牙槽嵴骨水平）评估患者年龄、性别、种植体修复/冠类型、冠固位及种植体冠状态等研究变量。所有数据均使用SPSS软件进行分析。
在所有研究的牙种植体中，201颗（42%）种植体的种植体周围黏膜一处以上出现探诊出血（种植体周围黏膜炎），115颗（23.76%）出现种植体周围边缘骨吸收。冠状态良好时PPD值显著更低（p<0.0001）。根据PI评分，大多数冠状态良好的患者无菌斑积聚（52.7%）。与65%未记录到探诊出血的患者相比，冠状态良好的患者中只有35%出现探诊出血。牙龈颜色（淡粉色和红色）与冠类型（烤瓷熔附金属冠与全瓷冠）显示出统计学上的显著关联（p = 0.005）。与仅6%的种植体螺纹暴露患者相比，大多数冠状态良好的患者影像学检查结果无变化（94%）（p<0.0001）。
种植修复因素的优化设计对于避免种植体周围黏膜炎/种植体周围炎的发生至关重要，在种植体修复治疗计划制定过程中必须予以考虑。
