This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency. Significant linear relationship was found between jaw movement sideways and masticatory efficiency. Descriptive analysis of the chewing pattern and the pattern for side changes was also made. The results of the present study can be used in diagnosing and monitoring therapy in patients with orofacial disabilities.
