Method and system for orthodontic diagnosis

An article of manufacture comprising a non-transitory program storage medium readable by a computer, the medium tangibly embodying one or more programs of instructions executable by the computer to perform a method for generating a cephalometric analysis of an orthodontic patient, comprising:

• receiving a sequence of images each corresponding to a specific anatomical plane of the orthodontic patient;
• deriving a volumetric representation of the orthodontic patient from a combination of the sequence of the images;
• receiving one or more markers associated with particular anatomical landmarks of the orthodontic patient according to a predefined analysis method, the markers being defined by a set of coordinate values referenced to the volumetric representation and designated via an interactive user interface to a series of two-dimensional representations of axial views, coronal views, and saggital views corresponding to the received sequence of images, the markers being designated in at least each one of views;
• generating connectors between one or more selected ones of the markers in accordance with the predefined analysis method;
• and
• overlaying a visual representation of the markers and the connectors on the volumetric representation;
• generating a profile outline of the orthodontic patient without user intervention based upon a chin point and a nose point derived from the received markers;
• and
• overlaying a visual representation of the profile outline on the volumetric representation;
• wherein the chin point and the nose point are identified from an intersection of common tangents of a first fitted circle based around a farthest point forward above a received marker corresponding to a point A, and a second fitted circle based around a farthest point forward from a Pogonion point intersecting with a soft tissue edge.
