Description

technical field [0001] The invention belongs to the field of auxiliary medical devices, in particular to a guide plate for orthognathic surgery and a manufacturing method thereof. Background technique [0002] In the treatment of patients with craniomaxillofacial malformations, surgery is often required to isolate the maxillary, mandibular and / or chin bones, move them into the correct position and fix the bone fragments in that position while establishing a stable bone. The occlusal relationship, such surgery is called orthognathic surgery. For patients who need simultaneous maxillary and mandibular surgery, the position of the maxilla after incision is determined by the position of the mandible before surgery, and the position of the mandible is fixed by the maxilla after moving and fixing the maxilla. The device used to guide the position of the upper and lower jaws during surgery is called a splint, the one used to position the maxilla is called an intermediate splint, a...
