1. A method for providing scanning guidance for a scanning device, comprising:

  • (a) receiving, at a computer system, user input selecting target parts of an intraoral cavity to be subsequently scanned by said scanning device;

    (b) determining, using the computer system, spatial relationships between the scanning device and said target parts of the intraoral cavity suitable for enabling said target parts to be subsequently scanned by said scanning device, wherein visual guide instructions for positioning and orienting said scanning device are generated by the computer system based on said spatial relationships; and

    (c) displaying, with the computer system on a display, said visual guide instructions for positioning and orienting said scanning device relative to the intraoral cavity in a manner substantially conforming to said spatial relationships;

    wherein said visual guide instructions comprise a symbol representative of a profile corresponding to an expected view of said target parts or of ancillary parts in said intraoral cavity associated with said target parts, the expected view corresponding to the determined spatial relationships, and the symbol comprising a line defining an interface between a plurality of image zones.
