Manufacturing method of tool for improving corticotomy

The invention relates to a manufacturing method of a tool for improving corticotomy. The method comprises the following steps: designing an osteotomy guide plate: designing the root quadrate bone cortex incision width according to the maxillary posterior depression in a treatment scheme, and determining the position of a mesiodistal virtual osteotomy line and the bone cortex incision length according to the depression tooth position, and determining the virtual osteotomy line and the bone cortex excision part, and printing osteotomy guide plates on the left, right, cheek and palate sides of the upper jaw; designing a zygomatic implant titanium plate: designing the zygomatic implant titanium plate at the zygomatic alveolar ridge according to the maxillary form shown by the CT of a patient;designing a cast transpalatal arch: designing the cast transpalatal arch according to a specific vertical control scheme through upper and lower dentition of the patient and palate vault superhard gypsum models or intraoral s
