Enhancing Facial Filler Training with 3D-Printed Models: A Prospective Observational Study on Medical Student Competence

BACKGROUND This study evaluated the efficacy of 3-dimensional (3D) printed facial models in training medical students for cosmetic facial filler applications. A prospective observational study included 40 medical faculty students without prior filler application or surgical training. They received theoretical and practical training using 3D-printed face models, assessed through pre- and post-training surveys. MATERIAL AND METHODS Facial models were designed using SolidWorks and printed with a Mars 2 PRO 3D printer using PLA filament and high-performance silicone. Training comprised in-class instruction, live demonstrations, hands-on practice, and individual guidance. Students' skills were assessed through self-assessments and objective criteria. RESULTS After training, students showed significant improvement in procedural understanding and application locations, with increased confidence and competence (P<0.001). Statistical analysis confirmed these improvements. CONCLUSIONS 3D-printed facial models are valuable for enhancing medical students' skills in cosmetic facial fillers, offering cost-effective and safe simulation. This approach improves practical skills and confidence, benefiting medical education and patient care.
