An orthognathic correction device includes a first retainer (100), a second retainer (200) and at least two elastic members (500). The first retainer (100) is configured to be removably worn on the maxillary dental arch (12) of a patient and has at least two first connection parts (306) fixed on the left and right buccal surfaces (100a, 100b) of the first retainer (100). The second retainer (200) is configured to be removably worn on the mandibular dental arch (22) of the patient and has at least two second connection parts (406) fixed on the left and light buccal surfaces (200a, 200b) of the second retainer (200). The elastic members (500) couple the first and second retainers (100, 200) worn and retained on the maxillary and mandibular dental arches (12, 22) of the patient, respectively, so as to drive the second retainer (200) to move relative to the first retainer (100), thereby adjusting the relative position between the mandible (22) and the maxilla (12) of the patient.
