Given the insufficient height of single-barrel fibula and inadequate bone volume of double-barrel vascularized fibula in mandibular reconstruction, it is a better choice to combine the upper full-thickness vascularized fibula with the lower half-thickness nonvascularized fibula. However, the nonvascularized fibula may fail due to complications, affecting the facial shape and occlusal function. Polyetheretherketone is a thermoplastic polymer used for bone defect reconstruction due to its good mechanical properties and biocompatibility. This case report mainly presents a secondary salvage reconstruction of the mandible by using customed 3-dimensional-printing polyetheretherketone, which restored the continuity and symmetry of the mandible, improved the patient's facial shape, and restored functional occlusion through dental implants. After a 28-month follow-up, no complications occurred, and the patient was satisfied with the final restoration.
鉴于单管腓骨高度不足和双管带血管腓骨骨量不足,用于下颌骨重建,将全长带血管腓骨与下半部非血管腓骨结合是更好的选择。然而,非血管腓骨可能会因并发症而失效,影响面部形状和咬合功能。聚醚醚酮是一种热塑性聚合物,由于其良好的机械性能和生物相容性,用于骨缺损重建。本病例报告主要介绍了使用定制的 3D 打印聚醚醚酮进行下颌骨二次挽救性重建,重建恢复了下颌骨的连续性和对称性,改善了患者的面部形状,并通过牙种植体恢复了功能咬合。28 个月随访后,无并发症发生,患者对最终修复效果满意。
