Research Abstract

Jerk-cost as a measure of jaw movement smoothness has been used to evaluate the masticatory function of patients with tooth loss and malocclusion. Jerk-cost measuring systems have thus far been unable to determine the jerk-cost of each chewing phase over time. The purpose of this study was to evaluate the effect of the changes of the occlusion by measuring the musticatory movement. In this study, the new methods were developed using an Accelerometer and verified the reliability of this method.
