    Abstract: A digital camera connects to a tooth shade analyzer subsystem, e.g., a digital video processor, and a color display monitor for the electronic determination of the color of patient's teeth. Preliminarily, the camera captures series of digital color images of tooth shades corresponding to reference shade guides, 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. 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.

    Abstract: An interactive dental restoration method, a system for use between a dentist, and a dental restoration laboratory. The method includes identifying a dental restoration need in a patient; designing a preliminary treatment plan that includes design criteria for preparation of a dental prosthesis to be placed in the patient to satisfy the dental restoration need; transmitting the preliminary treatment plan via a communications network to a dental restoration laboratory; and communicating a final treatment plan, including modifications to the preliminary treatment plan where necessary, to the dentist. The system includes a computer-based dental restoration system of a network server (1610) having a database (1630), a network (1620), and at least one local computer (14). The database stores information about materials, procedures, and preparations concerning dental prostheses.

    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).

    Abstract translation: 数字照相机（12）连接到例如数字视频处理器（14）的牙齿分析器子系统，以及用于电子确定患者牙齿颜色的彩色显示监视器。 最初，摄像机拍摄（26）一系列对应于参考遮光板引导件（34）的牙齿的数字彩色图像，并将参考阴影与患者牙齿的图像进行电子比较。 在优选实施例中，比较了一组伪像素，每组伪像素对应于高分辨率相机中的一组像素。 一旦找到匹配，就将其传送给系统（52）的用户。 在具体实施例中，相机配备有套筒和照明子系统，其有助于减少由于外部因素导致的数字图像的颜色变化。
