The free fibula flap is a reliable approach used to reconstruct maxillofacial osseous defects. Virtual surgical planning facilitates the execution of such segmental bony reconstruction, usually preceding the placement of endosseous implants for dental rehabilitation. Novel advances in digital technology allow for fabrication of 3D guides for implant placement in the fibula bone segments before their fixation to the facial defect, with reduced ischemic time, reduced treatment time, faster dental rehabilitations, and unprecedented improvements in the overall treatment efficiency. This case report illustrates the use of digitally designed 3D-printed surgical plates for a single-stage surgery of free fibula flap with implant placement. The patient was successfully treated and followed over 2 years. Comparison between preoperative virtual planning and postoperative scans revealed a high accuracy of implant and bone segment positioning.
游离腓骨瓣是用于重建颌面骨缺损的一种可靠方法。虚拟手术规划有助于此类节段性骨重建的实施,通常在植入骨内种植体以进行牙齿修复之前进行。数字技术的新进展使得在将腓骨骨段固定到面部缺损之前,能够制造用于在腓骨骨段中植入种植体的3D导板,从而减少缺血时间、缩短治疗时间、加快牙齿修复,并在整体治疗效率方面取得前所未有的提高。本病例报告阐述了使用数字设计的3D打印手术钢板进行游离腓骨瓣单阶段手术并植入种植体的情况。该患者得到成功治疗并随访了2年以上。术前虚拟规划与术后扫描结果的比较显示种植体和骨段定位具有很高的准确性。
