Abstract

Purpose: This study aimed to evaluate the clinical outcomes of a single type of narrow-diameter implant (NDI) by investigating its survival rate and peri-implant marginal bone loss (MBL). In addition, variables possibly related to implant survival and MBL were investigated to identify potential risk factors.

Methods: The study was conducted as a retrospective study involving 49 patients who had received 3.0-mm diameter TSIII implants (Osstem Implant Co.) at Seoul National University Dental Hospital. In total, 64 implants were included, and dental records and radiographic data were collected from 2017 to 2022. Kaplan-Meier survival curves and a Cox proportional hazard model were used to estimate the implant survival rate and to investigate the effects of age, sex, jaw, implant location, implant length, the stage of surgery, guided bone regeneration, type of implant placement, and the surgeon's proficiency (resident or professor) on implant survival. The MBL of the NDIs was measured, and the factors influencing MBL were evaluated.

Results: The mean observation period was 30.5 months (interquartile range, 26.75-45 months), and 6 out of 64 implants failed. The survival rate of the NDIs was 90.6%, and the multivariate Cox regression analysis showed that age was associated with implant failure (hazard ratio, 1.17; 95% confidence interval, 1.04-1.31, P=0.01). The mean MBL was 0.44±0.75 mm, and no factors showed statistically significant associations with greater MBL.

Conclusions: NDIs can be considered a primary alternative when standard-diameter implants are unsuitable. However, further studies are required to confirm their long-term stability.

3.0 毫米窄直径植入体的临床评估：一项长达 5 年观察期的回顾性研究。

目的：本研究旨在通过调查单一类型窄直径种植体（NDI）的存活率和种植体周围边缘骨质流失（MBL），评估其临床效果。此外，还调查了可能与种植体存活率和MBL相关的变量，以确定潜在的风险因素：该研究以回顾性研究的形式进行，共有 49 名患者在首尔国立大学牙科医院接受了直径为 3.0 毫米的 TSIII 种植体（Osstem Implant Co.）共纳入64颗种植体，并收集了2017年至2022年的牙科记录和影像学数据。采用卡普兰-梅耶生存曲线和 Cox 比例危险模型估算种植体存活率，并研究年龄、性别、颌骨、种植体位置、种植体长度、手术阶段、引导骨再生、种植体植入类型和外科医生水平（住院医师或教授）对种植体存活率的影响。对 NDI 的 MBL 进行了测量，并评估了影响 MBL 的因素：平均观察期为 30.5 个月（四分位间范围为 26.75-45 个月），64 个种植体中有 6 个失败。NDI 的存活率为 90.6%，多变量 Cox 回归分析显示，年龄与植入失败相关（危险比为 1.17；95% 置信区间为 1.04-1.31，P=0.01）。平均 MBL 为 0.44±0.75 mm，没有任何因素与 MBL 的增大有统计学意义：结论：当标准直径种植体不合适时，NDIs可被视为一种主要替代方案。结论：当标准直径种植体不合适时，NDIs 可被视为主要替代品，但仍需进一步研究以确认其长期稳定性。
