Improper reduction can lead to functional impairment, facial asymmetry, and poor esthetic results. Virtual surgical planning (VSP) and 3D printing have recently been introduced to enhance surgical precision through preoperative simulation and prebending of fixation plates. However, the clinical superiority of this technique over traditional surgical methods remains under investigation.\n\nObjective:\n\nTo compare the accuracy and clinical outcomes of virtual surgical planning and prebent titanium miniplates versus conventional open reduction and internal fixation techniques in the management of zygomaticomaxillary complex fractures.\n\nMethods:\n\nThis randomized clinical trial will include 20 patients diagnosed with unilateral ZMC fractures, divided equally into two groups.\n\nGroup I: Patients treated using virtual surgical planning with 3D model reconstruction, virtual reduction, and prebending of titanium miniplates.\n\nGroup II: Patients treated using traditional open reduction and fixation without virtual planning.\n\nAll surgeries will be performed under general anesthesia using standard approaches. Clinical evaluation will include assessment of facial symmetry, eye movement, enophthalmos, diplopia, wound healing, and postoperative complications. Radiographic evaluation will be conducted by comparing postoperative 3D CT scans (after 3 months) with preoperative virtual models to assess reduction accuracy and bone formation.\n\nStatistical Analysis:\n\nData will be analyzed using SPSS software. Descriptive statistics will be presented as mean ± standard deviation. Independent t-tests and ANOVA will be used to compare outcomes between groups, with significance set at p ≤ 0.05.\n\nExpected Outcomes:\n\nIt is anticipated that virtual surgical planning will yield superior anatomical accuracy, improved facial symmetry, and reduced intraoperative time and complications compared to conventional techniques.\n\nEthical Approval:\n\nApproved by the Research Ethics Committee, Faculty of Dentistry, Suez Canal University, on 30 September 2025 (Board Status: Approved).\n\nStudy Start Date: October 2025 Estimated Completion Date: October 2026",[43,50],{"label":44,"type":45,"description":46,"interventionNames":47},"Virtual Surgical Planning (VSP) - Prebent Miniplates","EXPERIMENTAL","Patients allocated to this arm will undergo preoperative CT segmentation and 3D reconstruction, virtual reduction of the zygomaticomaxillary complex, and 3D printing of the reduced model.
