Dental implants have emerged as a dependable solution for replacing missing teeth, boasting high survival rates. Nonetheless, implant placement marks only the initiation of a lifelong maintenance protocol. Ensuring the long-term success of dental implants hinges on the essential preservation of peri-implant tissue health and is dependent on patient compliance, which is considered a critical determinant in supportive care.
The purpose of this study is to retrospectively analyze peri-implant mucosal aspects from the time of baseline assessment to a follow-up period of 3.5-4.5 years.
This retrospective analysis included follow-ups of 68 patients who received one or multiple dental implants between 2011 and 2016. Baseline assessment took place around 8 weeks after placement of the final restoration to assess the peri-implant condition clinically and radiographically. Peri-implant bleeding on probing (PiBOP), peri-implant probing pocket depth (PiPPD), and gingival recession were recorded during every visit.
Implant-level analysis of PiBOP showed an increase from 31% at baseline to 48% at the follow-up appointment ( < 0.001). The average PiPPD at implant level was 3.2 mm at baseline and increased to 3.5 mm ( < 0.001). Male patients presented with significantly higher PiPPD values compared to female patients (implant level: =0.017, patient level: =0.039). There was no apparent difference in PiPPD between the group with a restoration with an emergence angle <30° or ≥30° (=0.912).
Peri-implant conditions remained fairly stable after the follow-up period. More effort needs to be made to improve the adherence of patients to peri-implant maintenance care.
牙种植体已成为一种可靠的缺牙替代解决方案，具有较高的存活率。然而，种植体植入仅仅是终身维护方案的开始。确保牙种植体的长期成功取决于种植体周围组织健康的必要维护，并且依赖于患者的依从性，这被认为是支持性护理中的关键决定因素。
本研究的目的是回顾性分析从基线评估到3.5 - 4.5年随访期的种植体周围黏膜情况。
这项回顾性分析包括对2011年至2016年间接受一个或多个牙种植体的68例患者的随访。基线评估在最终修复体植入后约8周进行，以临床和影像学方式评估种植体周围情况。每次就诊时记录种植体周围探诊出血（PiBOP）、种植体周围探诊袋深度（PiPPD）和牙龈退缩情况。
对PiBOP的种植体水平分析显示，从基线时的31%增加到随访时的48%（<0.001）。种植体水平的平均PiPPD在基线时为3.2毫米，增加到3.5毫米（<0.001）。男性患者的PiPPD值显著高于女性患者（种植体水平：=0.017，患者水平：=0.039）。在修复体龈缘角度<30°或≥30°的组之间，PiPPD没有明显差异（=0.912）。
随访期后种植体周围情况保持相对稳定。需要做出更多努力来提高患者对种植体周围维护护理的依从性。
