[Object] To provide, for a composite resin (CR) having a wide range of applicable colors (shades) (wide-ranging color applicable CR), such as a CR having light diffusion properties and a CR that produces color by means of a structural color, a technology with which an excellent effect, specifically, an increased breadth (number) of applicable shades in comparison to an existing CR other than a wide-ranging color applicable CR, can be achieved. [Solving Means] For example, in a demonstration instrument, a plurality of samples is prepared, a single wide-ranging color applicable CR has been used to restore a cavity in artificial teeth each having a different shade, the cavity being formed at a predetermined position of the artificial teeth, and the plurality of samples is disposed side by side and fixed on a display surface of a display plate, thereby making it possible to compare/contrast conditions of restored portions of the samples to each other and the color tone applicability thereof to those of a teeth to be restored.
