[Expert consensus statement on reconstruction principle for mandibular defect].

Mandibular defect is one of the common defects of maxillofacial region, which can seriously affect the appearance, chew and speech. The ultimate goal of functional reconstruction of mandibular defect is to restore mandibular appearance, denture and occlusal function. Vascularized bone grafting is an effective method for reconstruction of mandibular defect, especially in treatment of large defect. However, functional reconstruction of mandibular defects involves multiple specialties, many technical details and long treatment cycle, resulting in a small proportion of functional reconstruction. To establish standard operating procedures, Society of Oral Maxillofacial Rehabilitation, Chinese Stomatological Association has organized a lot of experts to establish expert consensus statement on reconstruction principle for mandibular defect, referred to standard procedure of indication, preoperative evaluation, choice of donor site, digital technology aided surgery, recommendations of the operation in the process of residual mandibular position fixed, the mandibular body molding denture and common post-operative complications, in order to promote the reconstruction of mandibular defect treatment and improve the quality of reconstruction.下颌骨缺损是颌面部常见缺损之一，可严重影响患者容貌和咀嚼、语言功能，下颌骨缺损修复重建治疗的最终目标是恢复下颌骨外形、义齿修复以及咬合功能重建，血管化自体骨移植是下颌骨缺损修复重建的有效手段，其治疗大型缺损的优势更明显。但下颌骨缺损修复重建治疗涉及多个专业，技术细节多、治疗周期长，导致最终实现功能重建的比例并不高。为规范下颌骨缺损修复重建治疗流程，中华口腔医学会口腔颌面修复专业委员会牵头组织国内多名从事下颌骨重建工作的专家共同讨论，形成下颌骨缺损修复重建治疗专家共识，针对下颌骨缺损修复重建治疗的适应证选择、术前评估、供区选择、数字化技术的辅助提出治疗规范，针对手术过程中的残余下颌骨位置固定、下颌骨体部成形等操作、重建术后的义齿修复和常见并发症提出治疗推荐，促进下颌骨缺损修复重建治疗的推广，提高修复重建质量。.
