The aim was to assess the degree of radiographic peri-implant bone loss over a follow-up period up to 15 years. In addition, another aim was to identify risk indicators for peri-implant bone loss and for moderate-severe peri-implantitis at patient- and implant level.
This is a cross-sectional clinical and radiological study of 147 patients with a total of 425 implants in combination with data collected retrospectively for baseline variables. To calculate the peri-implant bone loss (primary outcome variable), the radiographic bone level measurements from baseline were compared to the radiographic bone level measurements at the final radiographic measurement. Multilevel analyses were adopted with peri-implant bone loss and peri-implantitis as outcome variables.
The mean follow-up time was 12.5 years (range 10-15) and the mean age of the patients was 63 years (range 29-83). The mean peri-implant bone loss was 0.94 mm (S.D. 1.3). The prevalence of moderate-severe peri-implantitis at patient level was 17% and 8.9% at implant level. The peri-implant bone loss was significantly more pronounced in healthy implants if moderate-severe peri-implantitis was present in at least one implant within the same patient. The presence of moderate-severe peri-implantitis was significantly associated with general periodontitis Stages III or IV at follow-up and smoking.
The presence of moderate-severe peri-implantitis at patient level was found to be a risk indicator of peri-implant bone loss in healthy implants, while smoking and general periodontitis Stages III and IV were risk indicators of moderate-severe peri-implantitis.
评估在长达 15 年的随访期间，种植体周围骨质的放射学骨丧失程度。此外，另一个目的是确定种植体周围骨质丧失和种植体周围炎的风险指标。
这是一项回顾性收集基线变量数据的 147 名患者共 425 枚种植体的横断面临床和放射学研究。为了计算种植体周围骨丧失（主要结局变量），将基线时的放射学骨水平测量值与最终放射学测量时的放射学骨水平测量值进行比较。采用多水平分析方法，将种植体周围骨丧失和种植体周围炎作为结局变量。
平均随访时间为 12.5 年（范围 10-15 年），患者平均年龄为 63 岁（范围 29-83 岁）。平均种植体周围骨丧失为 0.94mm（S.D. 1.3）。患者水平中度至重度种植体周围炎的患病率为 17%，种植体水平为 8.9%。如果同一患者的至少一个种植体存在中度至重度种植体周围炎，则健康种植体的种植体周围骨丧失明显更为明显。中度至重度种植体周围炎的存在与随访时的一般牙周炎 III 或 IV 期和吸烟显著相关。
患者水平中度至重度种植体周围炎的存在被发现是健康种植体种植体周围骨丧失的风险指标，而吸烟和一般牙周炎 III 期和 IV 期是中度至重度种植体周围炎的风险指标。
