Purpose: The aim of this study was to evaluate the role of using a prebent titanium mesh on a 3D-printed model as an intraoperative guide to reconstruct orbito-zygomatic-maxillary complex (OZMC) fractures. Subjects and method: This is a prospective, interventional, longitudinal, single armed case series study that was carried out on twelve patients with unilateral displaced orbito-zygomatico-maxillary complex (OZMC) fracture indicated for orbital floor reconstruction as evidenced by clinical and radiographic examination. Open reduction and internal fixation were utilized to treat those fractures, patients were collected from the department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University. Post-operative evaluation: all patients underwent regular follow up for six months. The following parameters were evaluated: visual acuity, external appearance of the eye including hypoglobus and enophthalmos, diplopia, ocular motility, the aesthetic results, orbital volume, area of bone defect, layout angle, gab length and the zygomatic reconstruction.
