Color measuring systems and methods such as for determining the color or
other characteristics of teeth are disclosed. Perimeter receiver fiber
optics are spaced apart from a central source fiber optic and receive
light reflected from the surface of the object/tooth being measured.
Light from the perimeter fiber optics pass to a variety of filters. The
system utilizes the perimeter receiver fiber optics to determine
information regarding the height and angle of the probe with respect to
the object/tooth being measured. Under processor control, the color
measurement may be made at a predetermined height and angle. Various
color spectral photometer arrangements are disclosed. Translucency,
fluorescence and/or surface texture data also may be obtained. Audio
feedback may be provided to guide operator use of the system. The probe
may have a removable or shielded tip for contamination prevention. A
method of producing dental prostheses based on measured data also is
disclosed. Measured data also may be stored and/or organized as part of a
patient data base.
