Patent ID: 8469705

Claim:
A method for orthodontic treatment planning of a patient with a workstation comprising a computing platform having a graphical user interface, a processor and a computer storage medium containing digitized records pertaining to a patient, said digitized records including image data, and a set of software instructions providing graphical user interface tools for access to said digitized records, the method comprising the steps of: designing a treatment plan for a patient with the aid of the workstation; identifying one or more constraints by way of placing markings on a first virtual model of the patient, whereby said software instructions in said workstation automatically enable showing said markings on a second virtual model of the patient; wherein either (a) said first virtual model is a two-dimensional virtual model and said second virtual model is a three-dimensional virtual model, or (b) said first virtual model is a three-dimensional virtual model and said second virtual model is a two-dimensional virtual model of the patient; simulating the movement of the teeth in accordance with the treatment plan as a series of two or more incremental tooth movement steps between an initial position and an ideal tooth finish position; and providing the user with the ability to interactively vary the tooth incremental steps and view on the workstation graphical user interface the associated impact on tooth position and space between teeth; whereby the user is able to interactively evaluate several alternative treatment scenarios by the variance in said incremental tooth movements steps.
