This invention discloses a gingival protection device for intermaxillary traction after orthognathic surgery, along with its manufacturing and usage methods. The device is a gingival protection bracket worn on the maxillary dentition, comprising a labial / buccal cover, a palatal cover, a blocking portion, and a connecting bridge. The labial / buccal cover conforms to the highest point of the tooth crown, while the palatal cover conforms to the entire palatal surface of the tooth crown, positioned between the intermaxillary traction rubber band and the gingival soft tissue. The blocking portion forms a protruding structure along the dentition direction on the labial side of the anterior teeth, mechanically limiting the intermaxillary traction rubber band during intermaxillary traction. The connecting bridge connects the labial / buccal cover and the palatal cover together in the posterior molar region on both sides. This device effectively blocks the direct action of the traction rubber band on the gingival soft tissue without affecting postoperative occlusal adjustment, improving posterior traction and occlusal stability and comfort, and aiding in rapid patient recovery. Furthermore, it balances wearing stability with the convenience of patient self-disposal.
