Description

A system for acquiring and sharing tooth color information and using it to manufacture artificial tooth colors customized to patients The present invention relates to a tooth color information acquisition and sharing system for manufacturing artificial tooth colors customized for a patient, and a method using the same. The invention relates to a method for reproducing the color of artificial teeth customized for a patient, wherein the artificial tooth color information is acquired according to standardized imaging conditions, the acquired natural tooth color information is easily shared with a remote operator, and the brightness and color tone of the acquired tooth photograph are always uniformly corrected so that an artificial tooth prosthesis can be produced based on accurate color information. Furthermore, the manufactured artificial tooth prosthesis is also photographed according to standardized imaging conditions, corrected in the same way, and then digitally overlaid by the artificial tooth photograph onto the natural tooth photograph to check the color matching results between the artificial tooth prosthesis and the natural tooth before the artificial tooth is actually placed in the oral cavity. In the process of fabricating artificial teeth to replace existing natural teeth for aesthetic or therapeutic purposes, high-resolution images of the teeth were captured and shared with the operator to match the color with the existing natural teeth. The problem is that even if high-quality tooth images are obtained when acquiring the color of natural or artificial teeth, distortion occurs during the process of acquiring and sharing tooth color information due to factors such as the photographer's skill level, shooting conditions, or shooting equipment. To resolve these issues, there is a need to develop a tooth color information acquisition and sharing system and a method for utilizing it to manufacture patient-customized artificial tooth colors, which minimizes distortion of color information during the process of acquiring color information from teeth and minimizes distortion during the transmission and reproduction of color information when transmitting the acquired tooth image color information to the operator.
