    摘要: 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.

    摘要: An improved light to frequency converter optical sensor and method using electronic bias. Adjustable gain also may be provided. A summing circuit sums electrical current from a photo detector and electrical current from a bias current circuit and provides the summed current to an integrator. A threshold detector comparator circuit has an input coupled to the output of the integrator and an output providing a series of pulses. The series of pulses has a frequency based on the light received by the photo detector and the electrical current from the bias current circuit.

    摘要: A method for preparing a dental prosthesis based on electronically determined image and color/shade data of a patient's tooth is disclosed. The image data and the color/shade data are displayed on a display device in the dental office. The image data and color/shade data are transmitted to a computing device at a remote location over a data communication channel. A telephone communication is established between a dental professional in a location proximate to the dental office and a dental technician or ceramist in a location proximate to the remote location while the dental professional and the dental technician or ceramist are commonly viewing the image and color/shade data. The dental prosthesis is prepared at the remote location based on the electronically transmitted image and color/shade data. Color/shade data of the dental prosthesis is electronically determined and the dental prosthesis is selectively modified prior to installing the dental prosthesis in the patient.
