1. A method for intraoral imaging, the method comprising the steps of:
(a) generating one or more output imaging signals from an intraoral probe;
(b) acquiring multimodal image content from each of a plurality of intraoral surface locations for a patient's dentition according to tissue response from the one or more output imaging signals and associating spatial coordinates to the multimodal image content;
(c) generating a stitched surface contour of the patient's dentition by reconstructing and stitching from a data subset of the multimodal image content, and preserving an association of spatial coordinates of the multimodal image content to the stitched surface contour;
(d) generating tooth outlines for one or more teeth from the stitched surface contour and arranging the tooth outlines as a dental chart representing a spatial ordering of the one or more teeth and of supporting gum tissue adjacent to the one or more teeth;
(e) populating the dental chart by analyzing the multimodal image content and indicating analysis results at one or more positions on the dental chart according to the association of spatial coordinates; and
(f) displaying the dental chart.
