Simulated Self‐Assessment and Error Correction in Preclinical Prosthodontics: Insights From 3D‐Printed Models
Résumé
Introduction Developing self‐assessment and defect correction skills is essential for dental students to ensure high‐quality clinical practice. However, these skills are often insufficiently addressed in dental education. This study evaluates students' ability to assess and correct crown preparation defects through a structured exercise simulating self‐assessment using standardised 3D‐printed models with deliberate flaws. Additionally, it examines their improvement during the correction phase and their satisfaction with this innovative approach. Materials and Methods Students evaluated crown preparation defects on standardised 3D‐printed models, guided by a rubric‐based evaluation table, and subsequently corrected these defects using rotary instruments. Their perceptions of the exercise were captured through a satisfaction questionnaire. Results 92% of students overestimated the presence or severity of defects during self‐assessment, with axial and occlusal reduction being the most challenging criteria. After the correction phase, students demonstrated significant improvement, particularly in axial reduction, although challenges persisted in occlusal reduction and finishing. Students expressed high satisfaction with the exercises, emphasising their value in enhancing learning and critical thinking. Conclusion This study underscores the importance of structured self‐assessment and correction exercises in dental education. By bridging the gap between self‐assessment and self‐correction, particularly in crown preparations, 3D‐printed models foster the development of clinical skills and autonomy amongst students.
