Digital Color Matching System on Dentures for Dental Practice

Project Details

Description

To combine with the contemporary color technology and the novel digital dentistry, this project intends to develop an electronic color matching system for dental practice. The standard calibration procedures for the color camera and the color monitor under relevant illuminating light sources will be exploited. One novel color scale exclusively for evaluating the denture colors is under study for higher efficiency in information exchange and communication. Unlike the conventional way by the conversion between chromatic coordinates of different instruments, the spectral analysis way will be adapted for better accuracy and wider applicability.The most frequently used dental technique in the color and shade matching of teeth is done manually and visually with dental color and shade guides. This method, shade matching is accomplished by visually comparing a tooth with multiple standards of the color and shade guide tabs. The selection done in this fashion is subjective and is influenced by the ability of the human observer to choose the best matching. Factors are including the observer color perception, observer bias, ambient lighting, and the acceptance threshold of mismatch. Only 40% of the matching results are satisfied to the patients and dentists. We expect to solve the essential issues on the color and shade matching for dental practice by reducing 50% of reproducing rate and improving the satisfaction up to 80%.
