Study designs: Randomized Controlled Trial, Clinical Trial

Abstract: BACKGROUND: Cadaveric dissection has traditionally been the cornerstone of anatomical education, yet limited access to cadaveric material necessitates alternative teaching methods. Mixed Reality (MR) and 3D printing offer immersive, interactive experiences that may enhance the understanding of complex anatomical structures. METHODS: 236 medical students were randomly assigned to three groups: MR, 3D printing, and control. Anonymized computed tomography angiography (CTA) data were used to generate 3D-printed models and holographic reconstructions. Students participated in structured anatomy sessions and completed an post-test assessment, followed by a second evaluation several weeks later. RESULTS: The MR group achieved the highest mean test scores, with a statistically significant difference from the control group (p < 0.05). No significant differences were found between the 3D printing and control groups. Most students rated both MR and 3D printing positively, with MR receiving the highest evaluations. However, follow-up assessments revealed no significant differences in delayed knowledge retention. CONCLUSIONS: MR and 3D printing are effective adjuncts to traditional anatomical education. MR demonstrated superior short-term knowledge acquisition, but delayed retention was comparable across groups. Further research should explore the impact of repeated exposure to these technologies in medical education.
