Understanding the morphology of teeth is crucial in restorative dentistry in terms of restoring teeth’ anatomy, aesthetics, and function. Objectives: (1) this study describes an innovative method of teaching and learning tooth anatomy that applied shading techniques to 3D drawing the molar occlusal surfaces; (2) the study aims to survey learners’ opinions about the method’s effectiveness. Materials and methods: This study was conducted on 118 third-year dental students at the University of Medicine and Pharmacy, Hue University, from March to May 2022. The 3D occlusal surface drawing was developed and applied in teaching, and feedback was received from students. All statistical analysis was analyzed using SPSS version 26.0. Results: Instructions for 3D drawing were detailed and explained step-by-step, from forming to shading the occlusal surfaces. Subsequently, 57.3% - 90.9% of students self-assessed their proficiency in comprehending the characteristics of the occlusal anatomy. 73.3% - 95.8% of students agreed on the utility. 73.1% of students agreed to be willing to apply the 3D drawing method in learning other subjects. Conclusion: Instructions for 3D drawing were built step-by-step, from forming to shading the occlusal surfaces. After completing the course, a high percentage of students agreed on the advantages of this method. Further studies are needed to evaluate the effectiveness of the 3D drawing method in clinical practice
