Abstract: Color/optical characteristics measuring systems and methods are disclosed. Perimeter receiver fiber optics/elements (7) are spaced apart from a central source fiber optic/element (5) and received light reflected from the surface of the object (20) is measured. Light from the perimeter fiber optics (7) pass to a variety of filters. The system utilizes the perimeter receiver fiber optics (7) to determine information regarding the height and angle of the probe (1) with respect to the object (20) being measured. Under processor control (20), 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 (1) may have a removable or shielded tip for contamination prevention.

Abstract: Optical characteristic measuring systems and methods for determining the color or other optical characteristics of teeth comprising a probe body (2) wherein the probe provides light to the surface of the object (20). Perimeter receiver fiber optics (102) are spaced apart from a source fiber optic and receive light from the surface of the object (20) being measured. Light from the perimeter fiber optics passes 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 being measured wherein the numerical apertures of the receiver fiber optics are different.

Abstract: 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 is part of a patient data base.
