【Hint】The McNamara analysis, originally published in 1983, combines elements of previous approaches with original measurements to attempt a more precise definition of jaw and tooth positions. In this method, both the anatomic Frankfort plane and the basion–nasion line are used as reference planes. The anteroposterior position of the maxilla and mandible are evaluated with regard to their position relative to the “nasion perpendicular,” a vertical line extending downward from nasion perpendicular to the Frankfort plane. The maxilla should be on or slightly ahead of this line, the mandible ...
