Table 2 Differences in mean values of the range of motion (mm) of patient groups with change or no change in disc positions after treatment; related to age, locking duration, maximum mouth opening, lateral and protrusive eccentric movements

From: Efficiency of pivot splints as jaw exercise apparatus in combination with stabilization splints in anterior disc displacement without reduction: a retrospective study
