Abstract: A method for determining a patient's tooth shade, by generating an electronic image of a patient's tooth wherein the image includes color information representative of the patient's tooth shade; storing color information representative of a plurality of tooth shades; and comparing the color information of the image with the stored tooth shade color information to identify one or more tooth shades having a combined color that corresponds to the patient's tooth shade. the image of the patient's tooth and the stored tooth shade color information are electronically displayed in color to enable a viewer to comparatively determine the color of the patient's tooth shade. Preferably, the patient's tooth shade is determined by selecting portions of the electronically displayed image of the tooth; determining the color of the selected portions; and comparing that color information with the stored tooth shade color information to determine the color of that portion of the patient's tooth. The selection of portions of the tooth is generally repeated until a tooth shade color is determined for all spatial locations of the image of the patient's tooth.

Abstract: A method and apparatus for reliably and accurately matching tooth color, in which a light source is provided with an illumination lens and a relay lens to direct light to illuminate a measurement point in a chosen zone of a tooth selected in a patient's mouth. Light reflected from the tooth is passed through a third lens which focuses the reflected light simultaneously on three detectors. Each detector is provided with a color filter positioned in front of it to allow for only one of the basic red, green and blue (R,G,B) colors to reach the detector. The three detectors produce an output signal representing the R,G,B color coordinate related to the measurement point. These signals are converted to digital data suitable to be further processed by a data processing and control unit, which maps the R,G, B values into values of Hue, Saturation and Intensity (H, S, I) which are normalized to represent a tooth color vector. The process is repeated for a total of three zones on the tooth, developing a color vector set for comparison with a predetermined color vector set to match the closest color vector, allowing the tooth color to be classified as corresponding to one of the colors in the Master Teeth Set.

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: A patient's dental prosthesis (e.g., a prosthesis tooth, crown, veneer, or bridge) is made by acquiring an image of the patient's teeth that contains black and white normalization references. These references are black and white porcelain, for example, that allow software of the invention to determine absolute black and absolute white within the color image. The acquired color image is then normalized in accordance with the normalization references, which corrects the image for variations in lighting conditions and image source. The normalized image is then standardized by matching the pixels of the normalized image to selected shade standards. The dental prosthesis can then be manufactured by a lab technician by referring to the standardized image. The tooth shade analysis and matching system is also applicable to direct restorations of natural teeth, such as repair of chipped or broken teeth. Methods of whitening teeth are also disclosed.

Abstract: A method and system for determining the color characteristic of a tooth, particularly in a mouth in which restorative dentistry is contemplated, employs the photographic imaging of the tooth of the patient, and the photographing of visually selected color standards, to achieve the final selection of the closest color match. The resulting photographic images, which may be on a single photograph, are subjected to calorimetric or spectrophotometric analysis to achieve the final selection of the closest match. The system avoids the need to rely upon the visual color acuity of the practitioner in order to achieve a close color match for a prosthetic device. Additionally, the method and system of the invention avoid the problems associated with color shifts associated with photography, when such is used alone as the indicator of tooth color.

Abstract: Disclosed in a method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation including shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.
