牙源性纤维粘液瘤（OFM）是一种圆形、局部侵袭性肿瘤，主要见于下颌骨。尽管放射学表现各不相同，但明确的诊断是基于与组织病理学检查的相关性。手术方法是首选治疗方法。对于重建，患者特异性种植体 (PSI) 最近已被开发为至关重要的帮助。本病例报告介绍了一名患有牙源性纤维粘液瘤的 19 岁女性患者，重点介绍了其临床、放射学、组织病理学特征，以及使用患者特异性种植体进行康复，降低了复杂性颅颌面区域缺损的手术修复和重建具有挑战性。所述治疗消除了骨移植的需要，由于更短的康复时间和更准确的配合而显示出最佳结果。本报告介绍了一种新技术，采用患者特异性植入物作为节段切除后重建的主要方法。版权所有 © 2024作者们。由爱思唯尔有限公司出版。保留所有权利。

Odontogenic fibromyxoma (OFM) is a round and locally invasive neoplasm predominantly seen in the mandible. Though radiographic appearance is variable, definitive diagnosis is based on correlation with histopathological examination. Surgical approach is the treatment of choice. For reconstruction, patient-specific implant (PSI) has lately been developed as a crucial help.This case report presents a 19 year old female patient with odontogenic fibromyxoma highlighting its clinical, radiographic, histopathological features along with rehabilitation using patient specific implants reducing the complexity and related morbidities of reconstructive procedures.Surgical repair and reconstruction of defects in cranio-maxillofacial region is challenging. The described treatment eliminates the need for bone grafting, shows optimal results owing to the shorter rehabilitation time and more accurate fits.This report introduces a novel technique whereby patient-specific implants are employed as the primary method of reconstruction following segmental resection.Copyright © 2024 The Authors.
