Study Of Computer Color Matching Of Maxillofacial Prosthesis

Maxillofacial Prosthetics as the special area of dental practice, which restore the orofacial defects with maxillofacial material to rehabilitate the patients appearance and function, that is an ancient art. Color selection and color matching are the key to success in the maxillofacial restorations. The color difference between the facial prosthesis and surrounding skin have long puzzled both of dentist and patient. The color matching of the restoration is a complex process, and now the dentists who select and evaluate the color of skin and restoration depend on perceptional method. The perceptional method relies on color perception by human eyes, which is affected by many factors: surrounding light condition, size of objective, background and eye fatigue. The purpose of this study is to introduce CCM technology into the color matching of maxillofacial restorations and set up a set of equations to increase the accuracy of color matching. This paper includes four parts.Part I The effect of pigments concentration on the physical and mechanical properties of the SY-1 silicone elastomerThe objective of this study is to confirm the optimum pigments concentration on the physical and mechanical properties and the maximum pigments concentration on the study of CCM. In this study, control samples were prepared...
