According to the color characteristics of maxillary central incisors will be divided into seven categories, namely, X1 ~ X7,[link widoczny dla zalogowanych], and found that most 15 to 30 years into the central incisors are X1 and X2 type. X1 is a single color, high brightness with only slight color change, transparency type is A, the color reproduction easier.

This method is simple. But the color to express a certain limit, and the optical effect of poor. VI staining within the color is easy to lose. so many years Colouring scholars committed to research and development of ceramic powder, and successfully produced a kind of ceramic powder. including dyeing, the dyeing of Noritake porcelain try for the Shofu porcelain powder also has been successful. Can such powder used in other powder, to be further explored. the advantages of dyeing technology is simple, easy to grasp and promotion; are free to express a variety of natural tooth color; optical effect; color of the teeth can be permanently stored within; also available at the bottom , physical layer, layer and layers on the cut ends were stained deeper within the dye layer, optical effect is better. the disadvantage of staining the optical effect of color than the color mixing method and the interpolation method is poor; need to build three Sheng; require multiple roasting ; need to craft a great deal of patience and a high artistic accomplishment in various tooth staining can be used for the color expression. and color mixing, color interpolation method and or staining compared to the staining technique is an ideal, practical expression of a variety of colors possible ways central incisor, promote the use of it in cosmetic dentistry is very necessary
