摘要： 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.

摘要： 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.
