Evaluation of Custom-Made Plates in the Treatment of Zygomaticomaxillary Complex (ZMC) Fractures

This prospective, single-arm clinical trial evaluated the clinical and radiographic outcomes of custom-made, 3D-printed titanium plates in the surgical treatment of unilateral zygomaticomaxillary complex (ZMC) fractures. The study assessed the accuracy of anatomical reduction, postoperative functional and esthetic outcomes, surgical efficiency, patient satisfaction, and postoperative complications.

Detailed Description

Patients with unilateral ZMC fractures requiring open reduction and internal fixation underwent virtual surgical planning based on preoperative CT imaging. Custom-made 3D-printed titanium plates were designed according to the patient's anatomy and used for fracture fixation. Clinical and radiographic outcomes were assessed postoperatively at 1 week, 1 month, and 3 months.

Intervention / Treatment
Experimental: Custom-Made 3D-Printed Titanium Plate
Custom-made 3D-printed titanium plates designed through virtual surgical planning based on preoperative CT imaging. The healthy side was mirrored to assist in virtual reconstruction and plate design. The plates were fabricated from biocompatible titanium and sterilized before surgery.
