Abstract: Various embodiments of an orthodontic appliance and method of forming such appliance are disclosed. In one or more embodiments, the orthodontic appliance can include an arch member including an arch member body and an arch member coupling connected to the body. The orthodontic appliance can also include an anchor including an anchor coupling and a base adapted to connect the anchor to a surface of a tooth. The arch member coupling can be releasably connectable to the anchor coupling, and the anchor can be adapted for displacement relative to the arch member body when the anchor is connected to the surface of the tooth and the arch member coupling is connected to the anchor coupling.

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.
