PROBLEM TO BE SOLVED: To obtain a denture which can obtain a good occlusal state. SOLUTION: This denture having a multilayered structure of two or more layers is formed to have an inner layer 6 having a higher wear resistance and/or hardness than the first layer 4 on the occlusal side has, at some position inside the second layer on the occlusal side. Since the denture 2 has the inner layer 6 having the higher wear resistance and/or hardness than the first layer 4 has, the wear of the tooth 2 is suppressed by the layer 6 even when the wear of the first layer 4 advances correspondingly to the life habit, such as the chewing motions or other motions related to occlusion of the wearer of the denture 2. Consequently, the excessive wear of the occluding surface of the denture 2 and the excessive change of the occlusal state can be avoided by the inner layer 6 and, therefore, each wearer can obtain a good occlusal state.
