Abstract
Creating a system to analyse human jaw motion is required for people affected with Temporomandibular Disorder. A guiding system is required for creating the rehabilitation steps in such cases. Currently, capturing and estimating the kinematics for the Temporomandibular Joint (TMJ) is difficult due to its intricate position. The capture of the motion by using the stationary camera is a common practice in the available market and gives a reasonable output; However, the setup cost of this instrument setup is too high. Hence, there is a need for a sensor system that is cost-effective and portable in nature. A sensory system is required which can record the kinematics of the motion of the jaw system with the required accuracy. In this paper, a simple system is proposed to capture the required information. The system would require a computer in close vicinity and would rely on a few software for post-processing of the signals obtained from the system. This could be used to reproduce the findings in 3D space and estimate the motion of the Mandible with respect to the skull (temporal bone) in real-time using a microprocessor. The results can also be used for carrying out the dynamic analysis on the TMJ for designing the implant or creating a guiding system for rehabilitation purposes. Benefits of the proposed system over the currently available sensor systems and limitations of the sensor system are discussed in the paper.
