Background
Clinically, for cranio-maxillofacial defect and fracture patients caused by tumor, trauma, developmental deformity and the like, a titanium alloy bone fracture plate (such as a small or micro titanium plate, a reconstructed titanium plate and the like) is mostly adopted to fix bone blocks, so that the normal anatomical form of the cranio-maxillofacial defect and the fracture is recovered, and the physiological function and the attractive appearance of the cranio-maxillofacial bone are finally recovered. In craniomaxillofacial deformity surgery, the traditional reduction method for the bone block moved after craniomaxillofacial osteotomy is determined by an occlusion guide plate, certain uncertainty is brought by the mobility of the mandible in the operation, and reduction is usually determined by an operator through experience and visual observation, so that complete accurate reduction is difficult to achieve, and the possible uncertainty of the operation effect is caused.
Meanwhile, in the subsequent cranio-maxillofacial bone fixation process, a doctor needs to bend, form and cut the bone fracture plate according to the bone morphology, fracture or defect condition of a patient so as to adapt to the bone appearance and size of the patient. However, due to the complex anatomical structure and contour of the cranio-maxillofacial bone, the titanium alloy plate cannot be accurately prepared into an internal fixture which is completely matched with the characteristics of the defect region such as morphology, biomechanics and the like by means of the traditional manufacturing process, bending by visual observation of a doctor not only increases the operation time, but also causes unnecessary damage to the surrounding anatomical structures such as nerve vessels and the like by repeated trimming and comparison, and simultaneously, the strength of the titanium plate is reduced by repeated bending of the titanium plate. And the effect of shaping the bone plate is different because the experience and the manipulation of each surgeon are different. If the shaping is inaccurate, the accuracy of the operation is affected, on one hand, the stability of the initial fixing stage is affected, on the other hand, the situation that partial bone plates are not matched with bone surfaces to cause overlarge pressure of individual point contact can exist, the resorption and even necrosis of local bone can be caused, operation errors are caused, and a patient cannot obtain ideal postoperative effects in preoperative planning.
