Abstract

Supplemental reference surface devices are provided for use in three-dimensional modeling of intra-oral scenes using identifiable positional characteristics from structured illumination or other techniques. Reference surface devices having at least one substantially plane smooth non-polished face are disclosed for locating the positions of intra-oral features, and for stitching together separate 3D tiles according to the identifiable positional characteristics. Reference can be attached to an intra-oral feature in or adjacent to the imaged intra-oral scene. Disclosed are reference surface devices having orientation and position indicia, as well as reference surface devices having a multiplicity of faces distributed in spatial position and angular orientation to facilitate correlation of 2D images obtained by imaging systems in different positions.
