Evaluating the Effectiveness of 3D-Printed Models in Tooth Morphology Training for Students

Area of Science:

• Dental Education
• Anatomical Modeling
• Digital Dentistry

Background:

• Traditional dental education relies on 2D visuals and physical models for teaching tooth morphology.
• Developing spatial understanding and manual dexterity is crucial for dental students.
• Three-dimensional (3D) printing offers a new avenue for creating accurate dental morphology models.

Purpose of the Study:

• To evaluate the effectiveness of 3D-printed models in dental education.
• To compare the impact of 3D models versus traditional methods on student performance.
• To assess the influence on both practical and theoretical learning outcomes.

Main Methods:

• Dental students were split into two groups: one using 3D models with traditional methods, the other using only traditional methods.
• Practical skills were assessed via soap carving and wax modeling.
• Theoretical knowledge was tested with a written exam, and student feedback was gathered via questionnaire.

Main Results:

• Students using 3D models showed significantly higher scores in soap carving, indicating improved accuracy.
• No significant difference was observed in wax modeling scores between groups.
• Theoretical exam results were similar, suggesting 3D models primarily enhance practical skills.

Conclusions:

• 3D-printed models are valuable tools for improving practical skills in dental morphology education.
• These models complement traditional teaching methods by supporting hands-on learning and visualization.
• The integration of 3D printing can enhance the spatial understanding and manual dexterity of dental students.
