Embodiment Construction
[0038]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0039] A method for manufacturing a 3D printed fibular reconstruction jaw surgery tool combined with bone resection and titanium plate positioning, comprising the following steps:
[0040] Step 1. Personalized sampling and surgical simulation: Use CBCT or spiral CT to scan the patient's upper and lower jaw and fibula donor sites, import the imaging data into the surgical design simulation software in Dicom standard format, use threshold division, region growth and multi-layer lasso and other functions to segment images and reconstruct the 3D models of the upper and lower jaws and fibula, such as image 3 shown.
[0041] Step 2. Determine the jaw osteotomy plane according to the extent of the lesion, draw multiple spatial points in the defect area to form a spatial fold line, and simulate the fibula transplantation to the jaw defect area to form...
