Abstract: An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.
