Abstract: A tooth shade scan system is provided that identifies tooth shades for a patient's tooth. An electronic database of tooth shade information for a shade guide may be stored. The database may include shade information based on tooth regions (e.g., the incisal, central, and cervical). A system operator may be shown an image of a patient's tooth on display equipment such as a computer monitor. An application running on the system may display dividers that the operator can manipulate to divide the image of the patient's tooth into regions. The regions may correspond to regions for which specific tooth shade information is available in the database. Values representative of a limited number of color characteristics for a region as a whole may be determined from the image. Corresponding categories of color characteristics may exist in the database, which is then used to identify tooth shades by region for the patient's tooth.

Abstract: The invention relates to a computer readable medium that includes one or more programs for carrying out a method for restoration of a patient's tooth. The method includes the steps of generating an electronic image of a patient's tooth; providing a preliminary treatment plan for addressing the dental needs of the patient; and forwarding the electronic image and preliminary treatment plan to a dental laboratory so that the technician can evaluate the image and treatment plan and in a manner such that the technician and dentist can review and discuss the preliminary treatment plan.

Abstract: A digital camera (12) connects to a tooth shade analyzer subsystem, e.g., a digital video processor (14), and a color display monitor for the electronic determination of the color of patient's teeth. Preliminarily, the camera captures (26) a series of digital color images of tooth shades corresponding to reference shade guides (34), and electronically compares the reference shades to an image of the patient's tooth. In a preferred embodiment the comparison is done over a set of pseudo-pixels, each corresponding to a group of pixels in an high-resolution camera. Once a match is found, it is communicated to a user of the system (52). In a specific embodiment the camera is equipped with a sleeve and illumination subsystems that help reduce the variations in the color of digital images due to external factors.
