The mandible is a critical structure of the lower facial skeleton which plays an important role in several vital functions. Segmental resection of the mandible is at times required in patients with advanced oral cavity malignancies, primary mandibular tumors, and radiation or medication induced osteonecrosis. Mandibulectomy can significantly decrease quality of life, and thus mandibular reconstruction is an important aspect of the operative plan. Mandibular reconstruction is challenging due to the complex three-dimensional anatomy of the mandible, and the precision required to restore dental occlusion in dentate patients. Significant advances have been made over the past decade in the ability to reconstruct and rehabilitate patients after a segmental mandibulectomy. This review will highlight these advances and discuss the timing of dental implantation.
下颌骨是面下部骨骼的关键结构，在多项重要功能中发挥着重要作用。对于患有晚期口腔恶性肿瘤、原发性下颌骨肿瘤以及放射性或药物性骨坏死的患者，有时需要进行下颌骨节段性切除。下颌骨切除术会显著降低生活质量，因此下颌骨重建是手术方案的一个重要方面。由于下颌骨复杂的三维解剖结构以及为有牙患者恢复牙列咬合所需的精度，下颌骨重建具有挑战性。在过去十年中，节段性下颌骨切除术后患者的重建和康复能力取得了重大进展。本综述将重点介绍这些进展，并讨论牙种植的时机。
