Mandibular movement refers to the muscle- and ligament-activated border and/or intraborder movements of the lower jaw. There are five types of mandibular movements including rotational, horizontal axis, frontal axis, sagittal axis, and translational. Mandibular movement is affected by several factors such as the muscles used in suspending the jaw, mandibular articulation, and the synovial joint system. Study of this movement is important for the fields of dentistry and orthodontics as it describes the concepts related to dental occlusion and the masticatory processes of the jaw. A detailed understanding of each patient’s unique mandibular movement is also required for the proper design and creation of a customized prosthesis. It provides information regarding their occlusal habits and angle of dentition so a truly functional prosthesis can be formed. Information on mandibular movement is also an important part of dental and medical research pertaining to oral health, mandibular issues, and prosthesis design.
