Abstract:
Objective To set up a neural network model and system to be applied in color selection of anterior porcelain prosthesis, and to improve its cosmetic effect. Methods The image was automatically captured by digtal camera, and pre processed. The values based on the three stimulation value were adopted for the colour selection and tooth colour matches from nine zone colors with 21 point smoothly transitional calculation. The three dimension view of the teeth was recovered. Tooth colors storage was set up and the characteristics for sample teeth and lost teeth were selected and retrieved to match the colour through artificial neural network automatically for personalized design of teeth colour. Results The method of anterior prosthesis for computerized color selection based on artificial neural network had a higher accuracy. By comparision, the satisfaction of patients, dentists and viewers was much higher than that without computer aided design, and patients' eveluation for the prosthesis was higher than that of dentists. Conclusion The design system for colour selection of the front tooth prosthesis has a great value in clinical application, and it has developed the theory of artificial neural network used in the field of stomatology.
