    Abstract: PROBLEM TO BE SOLVED: To provide a tooth shade scan system and method to identify a tooth shade for a patient's tooth. SOLUTION: 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. COPYRIGHT: (C)2005,JPO&NCIPI

    解决方案：可以存储用于阴影引导件的牙线信息的电子数据库。 数据库可以包括基于牙齿区域（例如，切口，中心和宫颈）的阴影信息。 系统操作者可以在诸如计算机监视器的显示设备上显示病人牙齿的图像。 在系统上运行的应用程序可以显示操作者可以操纵以将患者牙齿的图像划分成区域的分隔线。 这些区域可以对应于数据库中特定牙齿信息可用的区域，可以根据图像确定表示整个区域的有限数量的颜色特性的值。 相应的颜色特征类别可能存在于数据库中，然后用于根据患者牙齿的区域识别牙齿。 版权所有（C）2005，JPO＆NCIPI

    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.
