3 THREE DIMENSIONAL MODEL BASED SURGERY GUIDE FOR MANDIBLE ANGLE REDUCTION SURGERY AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a guide mechanism for mandibular incision surgery and a method for manufacturing the same. More particularly, to a guide mechanism for protecting the nerve, soft tissue, and mandibular bone around the mandible and effectively guiding the movement path of the cutting instrument while being fixed to the exoskeleton of the mandible of the operation subject. The profile of the inner wall of the guide structure for mandibular resection surgery according to an embodiment of the present invention follows the shape of the outer surface of the outer surface of the three-dimensional model of the mandible before surgery of the operation subject. At this time, as a part of the guide structure for mandibular resection surgery, the boundary surface of the outer portion of the portion of the subject in contact with the outer surface of the mandible is formed along the cut surface in the preset simulation.
