B、Molar Fulcruming Due to Prema-turities: Figure A—2 has demonstrated normal jaw leverage in the sagrttal plane. Now let us examine what happens when we have a prematurity in the molar (or bicuspid) area and how this changes the lever system and consequently places greater stress upon the teeth. In a protrusive movement of the mandible, such as biting lettuce, etc, there may be a pattern of occlusion developing which results in a Class I lever system. As the jaw opens, nrotrudes, and attempts to close into
