The aim of this retrospective study was to evaluate the implant survival, clinical and radiographic outcomes, and patient satisfaction of single implant-supported two-unit cantilever fixed partial dentures in the posterior region.
Patients who received a single implant-supported fixed partial denture with a cantilever in the posterior region between January 2004 and February 2018 were included. Survival rate of the implants and the fixed partial dentures and data regarding the marginal bone level, presence of plaque, calculus, bleeding on probing, mucosa health, pocket probing depth, and patient satisfaction were collected during an evaluation visit. Complications were recorded from the medical records.
Twenty-three patients (mean age 64 ± 13 years) with 28 implants could be included in the study. The mean follow-up period was 6.5 ± 4.8 years at the time of data collection. The survival rate of the implants and fixed partial dentures was 100%. Mean marginal bone loss for the mesial and distal side of the implants was 0.41 mm (SD 1.18 mm) and 0.63 mm (SD 0.98 mm) respectively. A high prevalence of peri-implant-mucositis (89.3%) and peri-implantitis (17.9%) was observed as well as a limited number of technical complications. Patients were quite satisfied, as reflected by a mean VAS score of 94.0 ± 7.2 points (range 0-100) and a OHIP-NL49 score of 10.8 (range 0-196).
Single implant-supported fixed partial dentures with a mesial or distal cantilever can be a predictable treatment option in the posterior region, with stable peri-implant bone levels, minor technical complications, and very content patients. However, the prevalence of peri-implant mucositis and peri-implantitis was high.

本回顾性研究旨在评估在后牙区单个种植体支持的两单位悬臂式固定局部义齿的种植体存活率、临床和影像学结果以及患者满意度。
纳入 2004 年 1 月至 2018 年 2 月期间接受后牙区单个种植体支持的固定局部义齿修复的患者。在评估访问期间，收集了种植体和固定局部义齿的存活率以及边缘骨水平、菌斑、牙石、探诊出血、黏膜健康、探诊深度和患者满意度的数据。并发症记录自病历。
23 名患者（平均年龄 64 ± 13 岁），28 个种植体，可纳入研究。数据收集时的平均随访时间为 6.5 ± 4.8 年。种植体和固定局部义齿的存活率为 100%。种植体近中和远中边缘骨平均损失分别为 0.41mm（SD 1.18mm）和 0.63mm（SD 0.98mm）。观察到较高的种植体周围黏膜炎（89.3%）和种植体周围炎（17.9%）发生率，以及较少的技术并发症。患者满意度较高，平均视觉模拟评分（VAS）为 94.0 ± 7.2 分（0-100 分），口腔健康影响程度量表（OHIP-NL49）评分为 10.8 分（0-196 分）。
在后牙区，单个种植体支持的带有近中或远中悬臂的固定局部义齿是一种可预测的治疗选择，具有稳定的种植体边缘骨水平、较少的技术并发症和非常满意的患者。然而，种植体周围黏膜炎和种植体周围炎的发生率较高。
