Abstract

Objectives: This retrospective study aimed to evaluate the clinical outcomes associated with zygomatic implant (ZI) rehabilitation in partially atrophic edentulous maxillae over a mean follow-up period of more than 10.3 years.

Methods: All consecutive patients underwent ZI rehabilitation between 1999 and 2020, with a minimum follow-up period of 3 years. The primary outcome was the implant survaival rate. Secondary outcomes included the prosthesis success rate, complications, and Oral Health-Related Quality of Life.

Results: Of the 21 patients, treated with 27 ZIs and 48 conventional implants (CIs), 9 (42.9%) were females. The mean follow-up was 10.3 ± 5.7 years (range 3.2-23.4). ZI and CI survival rates were 100% and 97.9%, respectively, with one CI that failed. Eleven patients received 12 CIs placed in the pterygoid and tuberosity region. Most of the implants (81.33%) were immediately loaded, with 17 patients (80.9%) receiving 21 acrylic bridges. Of the total of 26 definitive prosthesis, the success rate was 96.1%. Local inflammation (n = 2) and soft tissue recession (n = 1) were reported as complications, occurring at a mean follow-up of 4.5 and 3.2 years, respectively. The mean score of the OHIP-14 questionnaire was 1.19 ± 1.99.

Conclusions: Unilateral ZI rehabilitation was a predictable option for patients with partially atrophic edentulous maxilla who have experienced previous graft or implant failures, or who require immediate loading. Splinting the ZI with CI for restoration appeared to be essential in unilateral ZI treatment. Complications were infrequent and could be managed effectively, with patient-reported outcomes indicating normalization in quality of life.

用单侧颧骨假体修复部分无牙上颌骨：一项长达 23 年随访的回顾性研究。

研究目的这项回顾性研究旨在评估平均随访时间超过10.3年的部分萎缩性无牙颌上颌骨颧骨种植体（ZI）康复治疗的临床效果：1999年至2020年期间，所有连续患者均接受了颧骨种植体（ZI）康复治疗，随访期至少3年。主要结果是种植体存活率。次要结果包括修复成功率、并发症和与口腔健康相关的生活质量：在接受 27 个 ZI 和 48 个传统种植体 (CI) 治疗的 21 名患者中，有 9 名女性（42.9%）。平均随访时间为 10.3 ± 5.7 年（3.2-23.4 年不等）。ZI和CI的存活率分别为100%和97.9%，其中一个CI失败。有 11 名患者接受了 12 个 CI，植入部位为翼突和结节区。大多数种植体（81.33%）都是即刻植入的，17 名患者（80.9%）接受了 21 个丙烯酸桥。在总共 26 个最终修复体中，成功率为 96.1%。据报告，局部炎症（2 例）和软组织衰退（1 例）为并发症，分别发生在平均 4.5 年和 3.2 年的随访期间。OHIP-14调查问卷的平均得分为1.19 ± 1.99：对于曾经历过移植或种植失败，或需要立即加载的上颌骨部分萎缩无牙颌患者来说，单侧ZI修复是一种可预测的选择。在单侧ZI治疗中，用CI夹板夹住ZI进行修复似乎至关重要。并发症并不常见，而且可以得到有效控制，患者报告的结果显示生活质量趋于正常。
