Few studies have reported the outcomes of short implants with a follow-up time > 10 years. This retrospective study aimed to evaluate the long-term outcomes of short locking-taper implants supporting single crowns in the posterior region. Patients who received these supporting implants (≤ 8 mm) in the posterior region from 2008 to 2010 were included. The clinical and radiographic outcomes and patient satisfaction were recorded. A total of 18 patients with 34 implants were included. The cumulative survival rate was 91.4% and 83.3% at implant and patient levels, respectively. Tooth brushing habit and history of periodontitis were significantly associated with implant failure (P < .05). The median marginal bone loss (MBL) was 0.24 mm (IQR: 0.01 to 0.98 mm). Biologic and technical complications occurred in 14.7% and 17.8% of implants, respectively. The mean modified Sulcus Bleeding Index was 0.52 ± 0.63, and the mean peri-implant probing depth was 2.38 ± 0.79 mm. All patients were at least quite satisfied, with the majority of patients (88.9%) being fully satisfied with the treatment. Within the limitations of this study, the short locking-taper implants supporting single crowns in the posterior region achieved promising outcomes in the long-term follow-up.
鲜有研究报道随访时间>10 年的短种植体的结局。本回顾性研究旨在评估在后牙区应用短款锁合锥形种植体支持单冠的长期疗效。纳入 2008 年至 2010 年间在后牙区接受这些支持性种植体（≤8mm）的患者。记录临床和影像学结局及患者满意度。共纳入 18 名患者的 34 枚种植体。种植体和患者水平的累积存活率分别为 91.4%和 83.3%。刷牙习惯和牙周炎病史与种植体失败显著相关（P<.05）。中位边缘骨吸收（MBL）为 0.24mm（IQR：0.01-0.98mm）。分别有 14.7%和 17.8%的种植体发生生物学和技术并发症。改良龈沟出血指数的平均值为 0.52±0.63，种植体周围探诊深度的平均值为 2.38±0.79mm。所有患者均至少为较满意，大多数患者（88.9%）对治疗非常满意。受本研究限制，在后牙区应用短款锁合锥形种植体支持单冠可获得长期良好的结局。
