摘要

The present invention relates to a method of manufacturing a recess wall lined with bristles for a mouthpiece for simultaneous brushing at a plurality of tooth positions, and a recess wall and a mouthpiece manufactured by the method of making a tooth. In the providing step, a long and continuous bristle sheet portion having a first side lined with a plurality of bristles is provided. The elongated seat portion defines a seat portion extending parallel to the sheave toe and a cross-sectional shape crossing the length axis. The sheet portion obtained in the providing step has a cross-sectional shape of an initial shape and an initial state which is an arch-shaped length axis. In the deformation step, the sheet portion of the providing step is deformed from the initial state to the final state to provide the relief wall. In the final state, the cross-sectional shape is the final U-shaped, the longitudinal axis is arcuate and the first surface is the final U-shaped concave inner surface. The first surface in the final state is more concave than the initial state.
