<p>A non-contact type dental shade matching device is provided, comprising a camera body (1) for capturing images of one or more target teeth (7); an opaque intra-oral compartment (4) snugly adapted for a human mouth; an opaque cover shield body (3) connected between the camera body (1) and the intra-oral compartment (4); one or more holders (9) for holding one or more shade tabs (6); and a color matching module being operably connected to the camera body (1) to receive the captured images containing color and translucency information of the target tooth (7) and/or shade tab (6) information, and then to process the images based on a content-based algorithm for automatic shade matching between the target tooth (7) and the shade tabs (6) for each of the captured images, so as to achieve an optimal dental prosthesis.</p> |
