Abstract: In order to assist in an orthodontics treatment, midline and molar relationship data are entered into a midline chart, first, second, third, fourth, fifth, and sixth crowding/spacing (C/S) data are entered into a discrepancy chart having first and second tables, and data from the first and second tables are entered into an anticipated treatment chart. The first table contains data related only to cuspid to midline regions of a patient's jaw, and the second table relates to second molar to midline regions of the patient's jaw and includes the cuspid to midline regions of the patient's jaw. The first C/S data relates to cuspid to midline regions, the second C/S data relates to bicuspid regions, the third C/S data relates to molar regions, the fourth C/S data relates to a curve of Spee, the fifth C/S data relates to midline position, and the sixth C/S data relates to incisor position.
