The occlusal contact area and force showed a tendency to decrease immediately after treatment and then gradually increase to pretreatment levels during the observation period. However, the occlusal contact area did not recover fully after 2 years in the four premolar extraction group.

The comparison of kinesiographic parameters between groups at T1 are presented in Table 1. No significant difference was found in most of the kinematic parameters between extraction and non-extraction groups before treatment. As shown in Table 2, on the other hands, opening and closing velocities significantly decreased, and turning point of chewing cycle displaced more superior at T2 in extraction group. Cycle time did not significantly differ between T1 and T2 either in extraction group nor in non-extraction group.
