Abstract：
A calcifying epithelial odontogenic tumor is a rare, benign odontogenic neoplasm. Surgical treatment is the option, and late recurrence is very rare. Radiologically, the lesions are commonly present scattered calcifications. This case report details a 64-year-old female patient with a recurrence of a right mandibular calcifying epithelial odontogenic tumor 2 decades after successful initial surgical removal. A segmental mandibulectomy and immediate reconstruction were performed using a planned vascularized free fibula flap with virtual surgery, custom reconstruction plate, and intraoperative computed tomography. Modifications were made to the design of the reconstruction plate to improve the cervicofacial profile and subsequent rehabilitation with dental implants. Fully guided implant surgery with point-of-care manufacturing protocol was done to improve prosthetically driven implant planning. The case presented highlights the usefulness of new technologies for mandibular reconstruction with the free fibula flap and the concept of point-of-care with technical notes that increase precision and reduce morbidity in implant-supported rehabilitation.
摘要：
钙化上皮牙源性肿瘤是一种罕见的，良性牙源性肿瘤。手术治疗是一种选择，晚期复发非常罕见。放射学上,病变通常存在散见性钙化。此病例报告详细介绍了一名64岁的女性患者，在成功进行初次手术切除2年后，右下颌钙化上皮牙源性肿瘤复发。使用计划的血管化游离腓骨皮瓣和虚拟手术进行了节段性下颌骨切除术和立即重建，自定义重建板，术中计算机断层扫描。对重建板的设计进行了修改，以改善颈面部轮廓和随后的牙科植入物康复。采用即时制造协议进行了完全引导的植入手术，以改善假体驱动的植入计划。所介绍的案例强调了使用游离腓骨皮瓣进行下颌骨重建的新技术的有用性，以及点护理的概念，其技术注释可提高植入物支持的康复中的精度并降低发病率。
