The first retainer is configured to be removably mounted on the maxillary dental arch of the patient and has at least two first connection parts fixed on the left and right ball faces of the first retainer. The second retainer is configured to be removably mounted on the mandibular arch of the patient and has at least two second connecting parts fixed on the left and right ball faces of the second retainer. The resilient member engages the first retainer and the second retainer held and held on the maxillary dental arch and the mandibular arch of the patient, thereby driving the second retainer to move relative to the first retainer, To adjust the relative position between them.
