A method for making a tool for improving cortical incision

Abstract

The invention relates to a method for making a tool for improving cortical bone incision, comprising the following steps: designing an osteotomy guide plate: designing the root side cortical bone resection width according to the depression of maxillary posterior teeth in the treatment plan, and determining the near tooth position according to the depressed tooth position. The position of the distal virtual osteotomy line and the length of the cortical bone resection were determined, and the virtual osteotomy line and the bone cortex resection site were determined to print the left and right maxillary, buccal and palatal side osteotomy guide plates; the design of the zygomatic implant titanium plate: according to the maxillary bone shown in the patient's CT Design the zygomatic implant titanium plate at the zygomatic alveolar ridge; design and cast the transverse palatal bar: design and cast the transverse palatal bar according to the specific vertical control plan based on the patient's upper and lower dentition and palatal arch superhard plaster model or intraoral scanning data; use 3D printing The designed osteotomy guide plate, zygomatic implant titanium plate and cast transverse palatal rod were made into real objects in a unique way. The invention can reduce trauma and financial burden of patients.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical devices, in particular to a method for making a tool for improving cortical bone incision. Background technique [0002] Orthognathic surgery is often required for patients with skeletal class II high angle to cut off the upper and lower jaws and move the upper and lower jaw pieces to establish a stable occlusal relationship. Fewer patients are discouraged. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a tool making method for improving cortical bone incision, which can reduce the trauma and economic burden of the patient. [0004] For patients with skeletal class II high angle and indications for orthognathic surgery, the modified buccal and palatal cortical incision of bilateral maxillary posterior teeth, bilateral maxillary zygomatic titanium plate implantation, and cast transverse palatal rods to depress maxillary poste...
