Description

technical field

[0001] The invention relates to a method for assisting doctors in positioning the prosthetic body in the human skull during cranioplasty, in particular, placing and fixing the personalized cranial prosthetic body made by computer three-dimensional modeling on the human skull defect precisely through surgery method of parts. Background technique

[0002] Due to accidents, diseases and other reasons, the bones are severely damaged and osteonecrosis, so there must be an object to replace the bones to protect and support the human body. The use of computer three-dimensional modeling method to shape the restoration is also a hot spot in research.

[0003] There are many methods for preparing bone prostheses, some of which can provide patients with high-precision bone prostheses that meet their individual needs, such as a titanium alloy for human bone defects introduced by Chinese invention patent CN200710044256.2. The restoration method can obtain a titanium all...
