Zygomatic implants are successful alternatives to conventional dental implants for oral rehabilitation of patients with severely atrophic maxillae; however, the use of unilateral zygomatic implants needs to be studied further to validate their efficacy. The present investigation aimed to evaluate unilateral zygomatic implant placement in the oral rehabilitation of partially edentulous patients with extremely atrophic maxillary bone and/or previous implant failures.
This retrospective clinical study included patients with partially edentulous maxillae who underwent unilateral zygomatic implant insertion. The primary outcome was implant survival. Intraoperative, postoperative and prosthetic complications were also assessed based on patients' clinical records.
A total of 32 patients (34 zygomatic implants) with a mean age of 60.45 ± 8.74 years (range 47 to 78 years) were included in the study. The mean follow-up period was 34.3 ± 25.5 months, and the overall implant survival rate was 100%. No intraoperative or postoperative complications developed in any of the patients, and no prosthesis failures or complications were recorded.
The results indicate that unilateral zygomatic implant insertion for oral rehabilitation of patients with partially edentulous posterior maxillae with severely atrophic bone and/or previous implant failures can be considered a successful alternative to use of conventional dental implants associated with advanced bone grafting procedures.
颧骨种植体是传统牙种植体在严重上颌萎缩患者口腔修复中的成功替代品；然而，单侧颧骨种植体的使用需要进一步研究，以验证其疗效。本研究旨在评估单侧颧骨种植体在严重上颌骨萎缩和/或先前种植体失败的部分无牙患者的口腔修复中的应用。
本回顾性临床研究纳入了接受单侧颧骨种植体植入的部分上颌无牙患者。主要结局为种植体存活率。根据患者的临床记录，还评估了术中、术后和修复体并发症。
共有 32 名患者（34 个颧骨种植体）纳入研究，平均年龄为 60.45±8.74 岁（47-78 岁）。平均随访时间为 34.3±25.5 个月，总体种植体存活率为 100%。所有患者均未发生术中或术后并发症，也未记录到修复体失败或并发症。
结果表明，对于严重上颌骨萎缩和/或先前种植体失败的部分上颌后牙缺失患者的口腔修复，单侧颧骨种植体植入可以替代传统牙种植体联合先进植骨术，是一种成功的选择。
