The Use of 3D‐Printed Teeth Models for Crown Preparation Training: Perceptions of Postgraduate Dental Trainees

European Journal of Dental Education, EarlyView.
ABSTRACT Background Typodont teeth used in preclinical dental training often lack the anatomical fidelity and tactile realism of natural dentition. With advancements in 3D printing, it is now feasible to design and fabricate highly realistic, patient‐specific tooth models for educational use.
