PROBLEM TO BE SOLVED: To provide an orthodontic apparatus having an excellent aesthetic property and dispensing with attachment/detachment thereof in an MRI.SOLUTION: The orthodontic appliance employs a thermoplastic resin or a thermosetting resin as a resin, and a composite material can be formed by mixing the resin with cellulose nanofibers and molding a mixture. For example, a method such as extrusion molding, injection molding, compression molding, and molding into a prescribed shape by cut machining is adopted to mold the mixture. Preferably, the cellulose nanofiber to be mixed with the resin has hydrophobicity. |
