Designing Modular Bite Force Measurement System for Stomatognathic Considerations

The stomatognathic system is a very complex structure that includes the temporomandibular joint, masticatory muscles, teeth, gingiva, tongue, and pharynx. In this structure, maximum bite force measurement has been an important field of study in the diagnosis and treatment of diseases caused by disorders related to chewing habits. Since existing measurement systems are expensive and impractical, researchers are in search of better systems. In this study, a modular and low-cost system has been developed to measure the bite forces accurately. The sensor data read by the microprocessor were converted to force values by the optimum curve fitting methods and results are instantly displayed on the user screen. The five different curve fitting functions were used to obtain the best results according to the goodness-of-fit statistics. The exponential equation was selected as the curve fitting method from the results of the goodness-of-fit statistics. The results were verified and system was calibrated by comparing the applied force values and system results.
