An orthodontic maxillary micro implant includes a plate and a corrective accessory. The plate is implanted into the keratinized epidermal tissue in the maxilla of the orthodontic patients oral cavity. First and second locking elements are passed through first and second locking holes situated at both ends of the plate respectively to secure the plate to the maxilla, and finally a third locking element is affixed through a fourth locking hole situated on the corrective accessory and a third locking hole situated on the plate to secure the corrective accessory to the maxilla. The orthodontic maxillary micro implant overcomes the difficulty of tongue operation and reduced oral hygiene maintenance caused by the large surface area that a conventional maxillary device occupies. With the use of orthodontic wires, the orthodontic maxillary micro implant becomes an orthodontic accessory allowing the patients teeth to be moved backward, pulled forward, pushed sideways or retracted.
