Using free navigation reference points and prefabricated bone plates for zygoma fracture model surgeries

A personalized preoperative modeling system for internal fixation plates in long bone fracture surgery—A straightforward way from CT images to plate model

“…Previously published papers revealed that this area of research has emerged in recent years, and there are few studies related to this research issue. The methods presented in previous studies highlighted the challenges and new trends of computer‐based processes for planning bone fracture reduction. In these methods, they mainly focus on how to utilize navigation reference points (screws position) to mold fixation plates.…”

“…This system also calculates the ideal positions of navigation reference points for screw holes. The experimental results show that combining presurgical planning and the developed navigation program to generate free navigation reference points (FNRPs) to assist with secondary zygoma reduction is an accurate and practical method . In the study of Moiduddin, two customized implant design techniques (mirroring/anatomical) were compared, and the best design was selected based on the surface deviation.…”

Additionally, an implant design model was evaluated using 3D finite element analysis to evaluate the biomechanical response of the implant under chewing conditions.…”
