<p>Orthodontic forces dependent on bone density measurements are determined by measuring bone density data in a scan of at least a portion of the teeth and jaw to produce a visual map of bone density is a selected area of the jaw. A two or three dimensional image of at least a portion of the jaw and teeth in the selected area of the jaw is generated. The bone density image is mapped into the two or three dimensional image. The attachment points on selected teeth, selected positions in the jaw, and/or selected orthodontic appliances to be connected to the teeth or jaw is determined. A force to be applied to the determined attachment points to move at least one tooth a predetermined distance and direction in the jaw taking into account the bone density through which the at least one tooth must move is calculated.</p> |
