Temporomandibular joint (TMJ) ankylosis is a joint disorder which refers to bone or fibrous adhesion of the anatomic joint components and the ensuing loss of function. This report describes the management of a case of bilateral TMJ ankylosis in a 20-year-old patient with prosthetic replacement with the aid of a piezoelectric instrument (MECTRON (R).
The right ankylotic mass was surgically removed and replaced by a custom-made prosthesis based on data obtained from three-dimensional computed tomography (CT) reconstruction of the skull of the patient using a stereolithography model.
At six months postoperative, the opening of the mouth was stable at 36 mm and imaging studies (CT and magnetic resonance imaging [MRI]) showed a great condylar prosthesis and surrounding tissues in addition to partial remodeling of the left TMJ.
In this patient, despite the bilateral ankylosis, it was sufficient to intervene only on the right TMJ, which presented a serious bone block, with mobilization since surgery gradually restored the anatomical and functional conditions of the left TMJ compatible with normal activities of mastication and speech.
颞下颌关节（TMJ）强直是一种关节疾病，指解剖学关节组件的骨或纤维粘连以及随之而来的功能丧失。本报告描述了一名20岁双侧TMJ强直患者借助压电仪器（MECTRON（R））进行假体置换的治疗情况。
通过手术切除右侧强直块，并根据使用立体光刻模型对患者颅骨进行三维计算机断层扫描（CT）重建获得的数据，用定制假体进行置换。
术后六个月，张口稳定在36毫米，影像学研究（CT和磁共振成像[MRI]）显示除左侧TMJ部分重塑外，有一个很棒的髁突假体及周围组织。
在该患者中，尽管是双侧强直，但仅对存在严重骨块的右侧TMJ进行干预就足够了，自手术起的活动逐渐恢复了与正常咀嚼和言语活动相适应的左侧TMJ的解剖和功能状况。
