Description

Technical Field

[0001] The utility model relates to the technical field of application of implant support nails in oral and maxillofacial surgery, in particular to an intermediate plate guide plate of implant support nails in orthognathic surgery. Background Art

[0002] Among patients who undergo orthognathic surgery, there are often patients who undergo preoperative invisible correction orthodontics, patients who prioritize surgery, and patients who only undergo orthognathic surgery and do not need orthodontic treatment. These patients do not have orthodontic brackets and archwires in their mouths, and cannot achieve intermaxillary traction after orthognathic surgery. In the past, these patients often used dental arch splints to achieve intermaxillary traction after surgery, but the operation time of dental arch splints is long, the foreign body sensation in the mouth is very obvious, the ligature wires often irritate the oral mucosa, and the removal of dental arch splints also requires a long operation time. For this reason, many doctors choose to implant anchorage nails in the upper and lower jaws during orthognathic surgery to complete intermaxillary traction with anchorage nails, but the direction and angle of implant anchorage nails often rely on the doctor's experience and judgment, which can easily damage the roots of adjacent teeth.
