Mandibular movement analysis is an integral part of the diagnosis and treatment processes in the domains of prosthodontics, orthodontics, or orthognathic surgery and remains a subject of research for many years. For the stomatognathic system to work physiologically, in mastication, swallowing, and speaking, stability and proper dynamics in the movement are crucial. The TMJ's intricate anatomy and biomechanics require complete harmony in order to be healthy and functional. A major implication might result from any problem or malfunction that impacts even one of the system's components, eventually triggering the onset of temporomandibular disorder. Six degrees of freedom (6 DOF) – three translational and three rotational, which correspond to all conceivable motion axes of a rigid body in a three-dimensional space, are used to biomechanically describe the mandibular kinematics. Pure rotation or translation in TMJ function is a rare occurrence. For many years, in the field of traditional prosthodontics workflow, instrumentation appears in the form of mechanical articulators and face bows. However, due to the articulator's basic design and the lack of patient-specific movement modeling, there are still unavoidable limitations. In the era of digital dentistry, innovative and efficient instruments for treatment planning and diagnostics in orthodontic and prosthodontic workflow, as well as in gnathological research, are jaw motion tracking systems (JMT). The aim of this literature review was to describe digital protocols and to characterize methods and instruments that enable individualized treatment of patients in the field of complex mandibular movements.
