A computer-aided analysis on dental prosthesis shade matching

Recently dental aesthetics become important requirement when people went to dental clinic. Thus, for the most of dental patient if placed prosthesis, an ideal prosthesis is that the color closes to the adjacent teeth, so the tooth matching become a crucial step before implant. In this paper we proposed a tooth shade matching system by develop a standard procedure, which is use a digital camera and ring light to take a dental picture and color correction for the consistency of dental image, cluster the color spectrum of the tooth for matching with the shade guide tabs. Finally we perform the system can be decision support system in the shade matching, increasing the correctness of shade matching. Qualitative interviews are performed; the results showed that most dentists satisfied the smooth standard procedure and the precision of clustering the color spectrum of tooth.
