A 3D-printed craniofacial fracture library with QR-integrated pedagogical content: a technical note for maxillofacial trauma teaching.

Maxillofacial traumatology requires mastering complex three-dimensional relationships that remain challenging to teach with conventional supports. Cadaveric dissection, still considered the gold standard, is increasingly restricted by tightening legislation on the academic use of human bodies. Radiological images and textbooks remain limited to two-dimensional projections. Three-dimensional (3D) printing provides tangible, reproducible and accessible models that can enhance spatial understanding. While 3D-printed anatomical models have already been reported in medical education, no permanent library dedicated to fractures in maxillofacial surgery has been described. We report the design and implementation of a 3D-printed fracture library installed in a university medical library, freely accessible to students and augmented with QR-coded pedagogical content. This pilot initiative demonstrates feasibility, reproducibility, and strong pedagogical potential, and may serve as a reproducible model for other institutions.
