Patent ID: 7698068

Claim:
A method of providing data useful in procedures associated with the oral cavity, comprising: providing at least two numerical entities, each numerical entity being representative of a three-dimensional surface geometry and color of a corresponding part of the intra-oral cavity including at least a first tissue thereof, wherein each numerical entity comprises surface geometry data and color data associated with the respective corresponding part of the intra-oral cavity, and wherein said at least two numerical entities spatially overlap at respective overlap portions; manipulating said at least two numerical entities to provide desired data therefrom; and (a) for each numerical entity providing at least one sub-entity comprising a first tissue data set exclusively comprising first surface geometry data and first color data corresponding to said first surface geometry data, wherein said first color data is correlated with a color representative of said first tissue, and wherein at least a first portion of said first surface geometry data corresponds to at least a part of the respective overlap portion of the respective numerical entity; and (b) stitching said at least two numerical entities together based on registering only said first portions of respective said first data sets.
