A masticatory orthodontic correction device 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 leaves a first space around a first tooth of the maxillary or mandibular dental arch. The first tooth is a tooth in malposition requiring correction, and the first space allows the first tooth to move therein during mastication. At least one buffering member is formed in the first space for transmitting and buffering force between the first recess and the first tooth. The orthodontic correction function of the device is active under occlusal loads generated during mastication.
