3d Printed Teeth: Anatomically Correct Primary Replicas, Anh Nguyen, Stefan Harris

Capstone Design Expo Posters

The current method of molding teeth, especially primary teeth, cannot accurately reproduce internal tooth structures. Therefore, there is a need for primary teeth to be made anatomically accurate on-demand with the ability to customize a model for specific patients. This project aims that any tooth extracted digitally from a Dental Cone Beam computed tomography (CBCT) scan of a child's mouth can be 3D printed into an accurate replicate with which dental students can practice. Constraints include viable materials that can be printed by a 3D printer, represent tooth anatomy and provide desirable mechanical properties compatible with the dental drilling operation. …
