Embodiment Construction
[0018] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0019] This embodiment is mainly used in total joint replacement treatment of temporomandibular joint ankylosis, advanced condylar osteoarthritis and various advanced condylar degeneration. Preoperatively based on the patient's CT data, use 3D reconstruction technology to accurately restore the patient's jaw model, and import the matching prosthesis data, and perform simulated implantation of the prosthesis on the digital jaw model, so as to determine the position and range of jaw grinding , direction and depth; CAD / CAM technology is used to design the osteotomy guide plate, and the digital design is transformed in...
