Abstract
A characteristic of optimal facial harmony is a correlation of the A/P (Anterior/Posterior) position of the maxillary incisors with the forehead. When the forehead is canted about 7 degrees or less, the A/P position of the maxillary incisors should match that of the middle of the forehead. For every degree the forehead is canted more than 7 degrees, the A/P position of the maxillary incisors should be 0.6 millimeters more anterior than the middle of the forehead. The extent to which the A/P position of the maxillary incisors is forward or back of the forehead's midpoint can be judged in millimeters quite accurately by viewing a patient in profile with the patient's forehead and maxillary incisors fully bared. Once the linear decision is made then the A/P treatment goal position can be physically measured and recorded using a novel bite fork (58), an improved facebow (56), and a new piece of equipment called a verticalizer (60). This information can then be transferred to and displayed on the occlusofacial simulator, a new kind of articulator.
