Abstract

Objectives

To assess the long-term clinical outcomes and patient satisfaction with narrow-diameter implants (NDIs) in the posterior jaws and to identify the risk indicators for NDI failure.

Materials and Methods

This retrospective study reviewed 479 patients with 666 NDIs (diameter ≤ 3.5 mm) -supported fixed prostheses in posterior jaws, with a minimum 10-year follow-up. Implant survival, success, complications, demographics, and implantation characteristics were collected. Risk indicators for posterior NDI failure were analyzed using multilevel Cox regression analyses with mixed effects. Patient satisfaction and oral health impact profile (OHIP) were surveyed in a random 10% sample.

Results

Over a mean follow-up of 14.0 ± 3.6 years, implant survival was 95.9% at the implant level and 94.6% at the patient level. Success rates were 93.5% at the implant level and 91.6% at the patient level. Multilevel Cox regression analysis identified an implant length of 10 mm or less (p = 0.001) and the use of single crowns (p = 0.005) as significant risk indicators for posterior NDI failure. Patients showed high satisfaction (4.54/5) with posterior NDIs, and the mean OHIP score of 1.15 reflected an acceptable level of oral health.

Conclusion

NDIs in the posterior jaws demonstrated robust long-term success and high patient satisfaction. An implant length of 10 mm or less and the use of single crowns are potential risk indicators for posterior NDI failure.

颚后部窄直径假体的长期临床效果和风险指标分析：10 至 27 年的回顾性队列研究

目的评估后颌窄径种植体（NDI）的长期临床效果和患者满意度，并确定NDI失败的危险指标。材料和方法本回顾性研究回顾了479例使用666个ndi（直径≤3.5 mm）后颌固定假体的患者，并进行了至少10年的随访。收集种植体存活、成功、并发症、人口统计学和种植体特征。采用混合效应的多水平Cox回归分析后验NDI失败的风险指标。随机抽取10%的样本，调查患者满意度和口腔健康影响概况（OHIP）。结果在14.0±3.6年的平均随访中，种植体水平的种植成活率为95.9%，患者水平的种植成活率为94.6%。种植体水平的成功率为93.5%，患者水平的成功率为91.6%。多水平Cox回归分析发现种植体长度小于等于10mm （p = 0.001）和使用单冠（p = 0.005）是后路NDI失败的重要危险指标。患者对后路ndi的满意度较高（4.54/5），平均OHIP评分为1.15，反映口腔健康水平可接受。结论后颌骨ndi治疗长期成功，患者满意度高。种植体长度小于等于10mm和使用单冠是后路NDI失败的潜在风险指标。中国临床试验注册：ChiCTR2200062337，注册日期：2022/08/02
