Abstract

Objective

To evaluate the influence of patient and implant-related factors on the changes of marginal bone levels (MBL) at implants with a follow-up ≥5 years.

Materials and Methods

At baseline (within 6 months from prosthetic insertion) and long-term (≥5 years after implant placement) visits, interproximal (mesial and distal) MBL were radiographically evaluated. To analyze factors predicting MBL change, the site (either mesial or distal) showing the highest MBL change (hChMBL site) was identified for each implant. Multilevel regression models were built to explain MBL change as well as the probability for a bone loss ≥2 mm at long-term.

Results

942 implants in 312 patients with a mean follow-up of 8.02 ± 2.5 years were analyzed. MBL change was significantly predicted by baseline MBL, oral bisphosphonate (BP) intake, history of periodontitis, diabetes, and super-hydrophilic implant surface. Higher risk for a bone loss ≥2 mm was observed in patients with history of periodontitis (OR = 9.52, 95% CI 0.72–3.79) and taking BP (OR = 6.84, 95% CI 0.21–3.63). Mandibular implants had higher odds for bone loss ≥2 mm compared to maxillary implants (OR = 3, 95% CI 0.39–1.87).

Conclusions

The findings of the present study contribute to the identification of specific clinical scenarios at higher risk for implant-supporting bone loss that need to be strictly monitored during maintenance.

影响牙科植入物至少 5 年功能的放射学边缘骨吸收的因素:一项多中心回顾性研究。
目的:评估患者和种植体相关因素对种植体边缘骨水平(MBL)变化的影响:评估患者和种植体相关因素对随访≥5年的种植体边缘骨水平(MBL)变化的影响:在基线(植入修复体后 6 个月内)和长期(植入种植体后≥5 年)随访时,对近侧(中侧和远侧)边缘骨水平进行影像学评估。为了分析预测 MBL 变化的因素,确定了每个种植体 MBL 变化最大的部位(中间或远端)(hChMBL 位点)。建立多层次回归模型来解释 MBL 变化以及长期骨量损失≥2 mm 的概率:结果:分析了 312 名患者的 942 个种植体,平均随访时间为 8.02 ± 2.5 年。基线 MBL、口服双膦酸盐 (BP)、牙周炎病史、糖尿病和超亲水性种植体表面对 MBL 的变化有明显的预测作用。有牙周炎病史(OR = 9.52,95% CI 0.72-3.79)和服用 BP(OR = 6.84,95% CI 0.21-3.63)的患者骨质流失≥2 毫米的风险更高。与上颌种植体相比,下颌种植体骨质流失≥2 mm的几率更高(OR = 3,95% CI 0.39-1.87):本研究结果有助于确定种植体支持骨质流失风险较高的特定临床情况,在维护过程中需要严格监控。
