A masticatory orthodontic correction device adapted to use occlusal loads generated during mastication as a correction force to achieve orthodontic correction, includes at least one correction unit with a rigid body. The correction unit is worn on a maxillary or mandibular dental arch of a patient during mastication, and the shape of the correction unit is maintained without deformation when accommodating teeth. At least one first recess is formed in the correction unit and has a shape which allows a first tooth of the maxillary or mandibular dental arch in malposition to move to the envisioned finish position. At least one buffering member is formed in the first recess configured to transmit and buffer the occlusal loads generated during mastication-between the first recess and the first tooth, wherein when the correction unit is worn during mastication, the buffering member deforms and contacts the first tooth over an area.
