A Full Digital VS Conventional Protocol in Management of Zygomatico-Maxillary Complex Fracture

Evaluation of the Accuracy of Zygomatico-Maxillary Complex Fracture Reduction And Fixation Using A Full Digital Workflow Versus Conventional Protocol: A Randomized Clinical Trial

this study aims To evaluate The Accuracy of Zygomatico- Maxillary Complex (ZMC) Fracture reduction and fixation Using customized Patient-Specific implant and patient-specific predictive holes surgical guide Versus Conventional Technique of reduction and fixation.

The ZMC has multiple points of articulation with the craniofacial skeleton making accurate assessment of reduction at all articulations intraoperative in multiple planes very challenging and the interference of soft tissue edema and a narrowed visual field increases the possibility of intraoperative overcorrection or underestimation of pre-injured position of all fracture lines at the same time resulting in a suboptimal reduction. As a trial to maximize the benefits of digital planning carrying the plan into a real operating room using a patient-specific surgical guide to predrill screw holes and guide patient-specific implants during fixation according to the planning depend on CT scan.
