Restoration of hemimandibulectomy defects following tumour extirpation to restore oral function is a herculean task for practitioners. Prosthetic treatment alternatives available for rehabilitation of acquired hemimandibulectomy defects according to mandibular reconstruction type and extent (Cantor-Curtis classification) are unclear. This systematic review aims to assess the spectrum of prosthodontic rehabilitation approaches with regard to reconstruction type and extent of mandibular surgical defects. The databases incorporated for literature search were Google Scholar and Medline (PubMed). Relevant search terms for hemimandibulectomy and reconstruction with prosthetic rehabilitation were used. Two reviewers independently assessed the articles using eligibility criteria; published case reports and case series in the English language and depicting prosthodontic treatment modality of patients greater than 15 years were included. A total of 202 records were identified from the database search of which 19 duplicates were removed. The remaining articles were assessed for eligibility, and 55 articles (comprising 58 cases) were finally included in the study. This review revealed various prosthetic alternatives ranging from guide flange, twin occlusion, palatal ramp, conventional to hybrid partial and complete dentures to implant-supported prosthesis including a few innovative prosthetic approaches. This systematic review provides a plethora of prosthodontic rehabilitation approaches according to the extent of hemimandibular surgical defect and type of reconstruction. This will facilitate practitioners and prosthodontists in sequential treatment planning and management of hemimandibulectomy cases in their routine practice.
肿瘤切除术后恢复半侧下颌骨切除术缺损以恢复口腔功能，对从业者来说是一项艰巨的任务。根据下颌骨重建类型和范围（坎托 - 柯蒂斯分类法），可用于后天性半侧下颌骨切除术缺损修复的修复治疗方案尚不清楚。本系统评价旨在评估针对下颌骨手术缺损的重建类型和范围的口腔修复方法的范围。纳入文献检索的数据库为谷歌学术和医学期刊数据库（PubMed）。使用了与半侧下颌骨切除术和假体修复重建相关的检索词。两名评审员使用入选标准独立评估文章；纳入以英文发表的病例报告和病例系列，且描述了15岁以上患者的口腔修复治疗方式。通过数据库检索共识别出202条记录，其中19条重复记录被删除。对其余文章进行入选资格评估，最终有55篇文章（包含58个病例）被纳入研究。该评价揭示了从导板、双咬合、腭斜面、传统到混合局部及全口义齿，再到种植体支持的假体等各种修复替代方案，包括一些创新的修复方法。本系统评价根据半侧下颌骨手术缺损的范围和重建类型提供了大量的口腔修复方法。这将有助于从业者和口腔修复医生在日常实践中对半侧下颌骨切除术病例进行序贯治疗规划和管理。
