| 1. A computer-based computer program product comprising a computer useable medium having computer readable program code embodied
therein for constructing a crown to be fitted on a tooth preparation in a patient, the computer program product comprising:
computer readable program code for causing the computer to define a finish line, comprising:
computer readable program code for causing the computer to provide three-dimensional (3D) digital data relating to the patient's
dentition, said 3D data including data representative of the surface topology of said preparation and its surroundings;
computer readable program code for causing the computer to generate first finish line data representative of at least a portion
of said finish line, and superimposing an image of said at least a portion of said finish line on an image of said dentition;
computer readable program code for causing the computer to obtain second finish line data on a finish line determined on the
basis of input received from a dental practitioner; and
computer readable program code for causing the computer to use said second finish line data to update said first finish line
data, and superimposing the updated data on the dentition image.
