[摘要]牙齿的微观美学指标包括形态、颜色、半透性、乳光性和荧光性、表面质感及光泽度、个性化染色着色特征等。只有进行系统全面的颜色信息获取和医技传递，才能实现修复体的个性化美学制作。牙齿的基本颜色按照颜色复杂程度准确进行分区确定，对切端颜色和半透明性信息进行个性化采集，同时定位获取牙体内部和表面的分区、分层个性化颜色信息，结合牙齿的形态学、表面质地和光泽度信息，采用口内数码影像向技师进行沟通和传递，这也成为当今牙齿个性化美学修复信息的系统化采集及传递的主要技术。本文就牙齿个性化美学修复颜色信息的获取与传递进行分析和阐述，以期为临床提供一定的指导。

    Sophisticated approaches in shade matching and communication of individualized tooth color information Meng Yukun.(Dept. of Prosthodontics, West China School of Stomatology, Sichuan University, Chengdu 610041, China)

    [Abstract]The microesthetics of teeth guide the creation of restorations with pleasing appearance that will blend in. Those aspects of single tooth such as morphology, shade, translucency, opalescence and florescence, texture and gloss, as well as tint and stain characterization are important elements. Individualized esthetic fabrication of appealing ceramic restorations can be achieved only if comprehensive and systematic color and related information were obtained clinically and precisely relayed to the dental technician, which includes the determination of the basic tooth color based on a shade guide in accordance with the porcelain system, individualization of the color and translucency of the incisal edge, precise location and recording of the surface and intrinsic color characteri-zation. By combining information of tooth shape, texture and gloss, all the information is transmitted to the tech-nician by means of series of digital photographs. All these techniques comprise the current mainstream in system-atic acquisition and communication of individualized esthetic and chromatic information. The purpose of this arti-cle was to provide some basic knowledge on those aspects of individualized esthetic and chromatic information for achieving superior clinical results. ......
