Follow-up results of modern zirconia implants inserted in fibula free and deep circumflex iliac artery (DCIA) flaps with fixed dentures are scarce. This study aimed to evaluate crestal bone changes and the survival rate of zirconia implants for up to 1.5 years of prospective follow-up.
Ten patients with six fibula and four DCIA flaps underwent reconstruction in the lower and upper jaws using vascularized composite flaps and were treated with zirconia implants. Peri-implant bone resorption was measured using radiographic images that were taken immediately after implant surgery (T1) and after three (T2), 12 (T3), and 18 months (T4).
Between the day of operation and T3, a significant increase in distance was recorded for the fibula flaps. After occlusal loading (T2) of 41 zirconia implants for up to 1.5 years, no significant bone loss in each flap was observed overall. An overall survival rate of 96.56% was reported.
When comparing both composite flaps, no significant difference in periimplant bone levels was measured between the same timepoints.
For fixed dentures, modern zirconia implants can be used in the DCIA and fibula flaps, however further long-term data is necessary.
关于在游离腓骨瓣和旋髂深动脉（DCIA）瓣中植入现代氧化锆种植体并安装固定义齿的随访结果鲜有报道。本研究旨在通过长达1.5年的前瞻性随访，评估氧化锆种植体的嵴顶骨变化和存活率。
10例患者，其中6例采用腓骨瓣，4例采用DCIA瓣，用上颌和下颌的带血管复合组织瓣进行重建，并接受氧化锆种植体治疗。使用种植体植入术后即刻（T1）、3个月（T2）、12个月（T3）和18个月（T4）拍摄的影像学图像测量种植体周围骨吸收情况。
在手术当天至T3期间，记录到腓骨瓣的距离显著增加。41颗氧化锆种植体进行咬合加载（T2）长达1.5年后，总体上每个瓣均未观察到明显的骨丢失。报告的总存活率为96.56%。
比较两种复合组织瓣时，在相同时间点测量的种植体周围骨水平无显著差异。
对于固定义齿，现代氧化锆种植体可用于DCIA瓣和腓骨瓣，但仍需要进一步的长期数据。
