Optical Mandibular Movement Tracking Devices, Clinical Uses and Indications

Recent advancements in digital dentistry have facilitated the accurate recording of dynamic mandibular movements using optical tracking devices, thereby improving the clinical outcomes and the patient's ability to adapt to their oral rehabilitation. This narrative review provides an overview of the evolution, functionality, and clinical applications of the mandibular movement devices and the current status of optical tracking devices in dentistry. Unlike traditional mechanical or electronic approaches, optical tracking devices offer noninvasive, real-time monitoring with high spatial precision. By accurately capturing patient-specific mandibular movements, these systems substantially improve the understanding of occlusal function, condylar motion, and temporomandibular joint dynamics, which enables the optimal design of prostheses tailored to individual patient anatomy, function, and esthetics. Optical tracking technologies can integrate successfully with digital workflows, including intraoral scanning and cone-beam computed tomography, thus enhancing diagnostic accuracy and facilitating precise treatment planning in prosthodontics and occlusal rehabilitation. Despite the challenges of optical tracking devices, such as high costs, system complexity, and calibration requirements, the optical tracking devices present a significant advancement in delivering individualised and functionally driven dental care.
