text: Since the mandible in a person, has a balancing function for the, cranium (pendular movement of the mandible as a counterweight), a detection was performed for the rotational center of the forward and backward movement of the mandible at mandibular resting position (mouth open gap of about 3 mm, mouth open angle of about 2 degrees) when projected onto a sagittal plane, and it turned out that the center lies at the apex of the dental cone which as mentioned is the center of stress, because the mandibular condyle moves forward and downward tangentially to the FH plane (horizontal plane) at about 50 degrees (because of the sagittal projection, the angle of the normal toward the dental cone apex becomes steeper from 33 degrees to about 40 degrees) and the front incisors of the mandible makes a tangential movement forming a right angle to the vertical axis.
