Disclosed is an orthodontic apparatus that has good aesthetics and does not require attachment / detachment during MRI imaging. An orthodontic apparatus can produce a composite material by using a thermoplastic resin or a thermosetting resin as a resin, mixing with cellulose nanofibers, and molding the mixture. For the molding of the mixture, for example, a method such as extrusion molding, injection molding, compression molding, or molding into a desired shape by machining can be employed. The cellulose nanofiber to be mixed with the resin is desirably hydrophobic. [Selection] Figure 1 |
