ObjectivesThis 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.MethodsAll 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.ResultsOf 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.ConclusionsUnilateral 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.

使用单侧颧骨植入物修复部分无牙颌的上颌骨：长达 23 年随访的回顾性研究


目的本回顾性研究旨在评估平均随访期超过 10.3 年与部分萎缩无牙上颌上颧骨植入物 （ZI） 康复相关的临床结果。方法所有连续患者在 1999 年至 2020 年期间接受了 ZI 康复，最短随访期为 3 年。主要结局是种植体存活率。次要结局包括假体成功率、并发症和口腔健康相关生活质量.结果在 21 例接受 27 例 ZI 和 48 例常规植入物 （CIs） 治疗的患者中，9 例 （42.9%） 为女性。平均随访时间为 10.3 ± 5.7 年 （范围 3.2-23.4）。ZI 和 CI 生存率分别为 100% 和 97.9%，其中 1 例 CI 失败。11 例患者接受了 12 个 CI，放置在翼状结肠和结节区域。大多数植入物 （81.33%） 立即加载，其中 17 名患者 （80.9%） 接受了 21 个丙烯酸桥。在总共 26 个确定性修复体中，成功率为 96.1%。局部炎症 （n = 2） 和软组织萎缩 （n = 1） 被报告为并发症，平均随访时间分别为 4.5 年和 3.2 年。OHIP-14 问卷的平均分为 1.19 ± 1.99.结论对于既往经历过移植物或种植体失败或需要立即负重的部分萎缩性无牙上颌患者，单侧 ZI 康复是一种可预测的选择。在单侧 ZI 治疗中，用 CI 夹板固定 ZI 以进行恢复似乎是必不可少的。并发症很少见，可以得到有效控制，患者报告的结果表明生活质量正常。
