Temporomandibular disorders (TMDs) refer to a range of conditions caused by anatomical and functional abnormalities of the temporomandibular joints. Anterior disc displacement with reduction (ADDwR) is one of the most common TMDs, characterized by symptoms such as jaw pain and audible clicking during jaw movements.
A 38-year-old female was admitted to our hospital in April 2023 with a chief complaint of joint snapping and jaw pain persisting for nearly a decade. After a comprehensive examination, she was diagnosed with ADDwR of bilateral temporomandibular joints. The patient then underwent functional anterior repositioning splint (FARS) therapy, which continued until July 2023, resulting in complete symptom remission. She is currently undergoing additional orthodontic treatment.
Anterior repositioning splint (ARS) therapy used to be considered one of the most effective therapies for ADDwR. However, concerns have emerged regarding its dependence on clinicians' subjective experience, potential inaccuracies in ARS design, and impact on patients' masticatory function. This case has improved the traditional ARS therapy with the establishment of a novel digital workflow to fabricate ARS with a fully masticatory function based on the virtual dental patient (VDP) for ADDwR. The FARS workflow ensured predictability and visualization of treatment effect through digital simulation, enhanced the personalization and precision of FARS design via VDP, and preserved the patient's masticatory function through the tailored design of occlusal surface morphology.
颞下颌关节紊乱病（TMDs）是指由颞下颌关节的解剖和功能异常引起的一系列病症。可复性盘前移位（ADDwR）是最常见的TMDs之一，其特征为下颌运动时出现颌部疼痛和可闻及的弹响等症状。
一名38岁女性于2023年4月因关节弹响和颌部疼痛持续近十年为主诉入院。经过全面检查，她被诊断为双侧颞下颌关节ADDwR。该患者随后接受了功能性前复位夹板（FARS）治疗，持续至2023年7月，症状完全缓解。她目前正在接受额外的正畸治疗。
前复位夹板（ARS）治疗曾被认为是ADDwR最有效的治疗方法之一。然而，人们对其依赖临床医生主观经验、ARS设计可能存在的不准确以及对患者咀嚼功能的影响产生了担忧。本病例通过建立一种新颖的数字工作流程改进了传统的ARS治疗方法，该流程基于虚拟牙科患者（VDP）为ADDwR制作具有完全咀嚼功能的ARS。FARS工作流程通过数字模拟确保了治疗效果的可预测性和可视化，通过VDP增强了FARS设计的个性化和精确性，并通过咬合面形态的定制设计保留了患者的咀嚼功能。
