PROBLEM TO BE SOLVED: To provide a denture which is easily adapted to a remaining tooth and can be easily attached and detached with one touch. A movable denture base is made of a polyamide resin and covers the front surface in the vicinity of the root of a remaining tooth. The hinge portion is provided on one side in the left-right direction of the fixed definition tooth bed portion. The recess 14 is provided on the other side of the solid definition tooth bed portion in the left-right direction. The convex portion 15 is provided on the other side of the movable denture base portion in the left-right direction. The groove portion 16 is provided on the contact surface 14s of the concave portion that contacts the tip surface 15s of the convex portion along the other side in the left-right direction in the oral cavity. The mounting pin 17 is provided so as to be able to enter and exit from the tip surface of the convex portion in the left-right direction in the oral cavity. The elastic member 18 presses the mounting pin to the other side in the left-right direction in the oral cavity. The inclined surface 19 is formed at the tip of the mounting pin from the tip surface of the convex portion. The protrusion 20 holds the mounting pin so as to be slidable in the left-right direction in the oral cavity.
