Comparison of Myo-Monitor centric position to centric relation and centric occlusion

Twenty dentulous subjects were selected at random. A Hight tracer, fixed on the labial surface of the teeth by special clutches, was used to indicate a record of centric relation and centric occlusion. The Myo-Monitor centric position was recorded and compared to centric occlusion and centric relation in anteroposterior and lateral dimensions. This study indicated that: 1. Myo-Monitor centric position is always anterior to centric relation, with an average of 3.8 min. 2. Myo-Monitor centric position is always anterior to centric occlusion, with an average of 1.8 mm. 3. In 18 of 20 subjects, the Myo-Monitor registration was to the right or to the left side of the line between centric relation and centric occlusion. 4. In all subjects, centric occlusion was an average of 2.2 mm. anterior to centric relation.
