Odontogenic myxoma is an odontogenic tumor of mesenchymal origin that presents locally invasive behavior. Its treatment is surgical, and the approach can be more conservative or radical. This article presents the rehabilitation of a patient with extensive odontogenic myxoma in the mandible treated conservatively with follow-up for 14 years. A 17-year-old male patient sought care with a painless swelling in the mandibular region causing facial asymmetry. Imaging exams showed a mixed image, with intralesional septa, involving the left anterior and posterior regions of the mandible with a small remaining basilar and lingual bone. An incisional biopsy was performed which confirmed the diagnosis of odontogenic myxoma. Due to the extent of the lesion, a conservative approach was chosen, with excision of the lesion and peripheral ostectomy, with recurrence of the lesion after 48 months, with a new approach being performed. After 14 years of follow-up, without further recurrence of the lesion, the patient was rehabilitated with dental implants and protocol-type prosthesis. Conservative treatment led to bone remodeling and enabled patient rehabilitation with oral implants and an implant-supported prosthesis. Thus, conservative treatment of odontogenic myxomas is a viable alternative for similar cases, and its longitudinal postoperative follow-up is essential.

牙源性黏液瘤是一种间充质起源的牙源性肿瘤，具有局部侵袭性。其治疗方法为手术，手术方式可较为保守或激进。本文介绍了一名下颌骨广泛牙源性黏液瘤患者的治疗情况，该患者接受了保守治疗并随访14年。一名17岁男性患者因下颌区域无痛性肿胀导致面部不对称前来就诊。影像学检查显示为混合影像，瘤内有间隔，累及下颌骨左前和后区域，仅残留少量基底骨和舌侧骨。进行了切开活检，确诊为牙源性黏液瘤。由于病变范围，选择了保守治疗方法，即切除病变及周边骨切除术，48个月后病变复发，遂采取新的治疗方法。经过14年的随访，病变未再次复发，患者通过牙种植体和定制型假体进行了修复。保守治疗导致骨重塑，并使患者能够通过口腔种植体和种植体支持的假体进行修复。因此，牙源性黏液瘤的保守治疗是类似病例的一种可行选择，术后长期随访至关重要。保守治疗、牙种植体、黏液瘤；口腔病理学、口腔外科。
