In recent years, the role of temporomandibular joint (TMJ) motion in the overall health of the orofacial system has increasingly captured the attention of the fields of oral medicine and rehabilitation medicine. The quantitative analysis of TMJ kinematics is crucial for understanding and treating orofacial functional disorders. This paper reviews the advancements in electronic axiography, optical motion capture, and dual-fluoroscopy imaging system (DFIS) technologies in clinical and research applications over the past decade. Electronic axiography and optical motion capture technologies, known for their high precision and real-time feedback, have been widely utilized in analyzing TMJ motion characteristics, evaluating treatment outcomes, and optimizing therapeutic techniques. The dual-fluoroscopy tracking technology demonstrates high accuracy and repeatability in analyzing complex joint motions. Although these technologies still face challenges regarding operational complexity, data stability, and safety, ongoing developments in motion analysis techniques and in-depth studies of orofacial system functions are expected to significantly enhance the precision and personalization of diagnostics and treatments for orofacial system diseases in the future.
