I recorded and analyzed electromyographic activity, incisal movement and condylar movement in 5 subjects to investigate the effect of the anterior guide angle on electromyographic activities in the inferior head of the leteral pterygoid muscle (Lpt) and the anterior belly of the digastric muscle (Dig). Increasing the angle significantly changed the electromyographic activities of Lpt and Dig. Significant correlation was found between electromyographic activity in Lpt and translation of condylar movement, and between Dig and mandibular rotation. It was found that protrusive movement could be performed smoothly by coordinating Lpt and Dig to accomodate changes in the anterior guide angle.
