Abstract: A boss assembly for attachment of hardware components to a dental appliance includes an anchor configured to be disposed on an external side of a dental appliance. The anchor has first internal threads on a proximal end and second internal threads on a distal end. The second internal threads are configured to cooperate with external threads of hardware components to be attached. A stud is configured to be disposed on an internal side of a dental appliance. The stud includes a flange on a proximal end and external threads configured to cooperate with the first internal threads of the anchor. The anchor and the stud are configured to join such that a wall of the dental appliance is captured between the anchor and the flange of the stud.

Abstract: The present disclosure provides systems and methods for designing a dental splint for an individual. For example, a method may include obtaining a digital 3D model of a dentition of the individual. An insertion direction is determined for the dentition. The method includes determining a height of contour for one or more teeth of the dentition based on the insertion direction. A cut line of the dental splint is identified based on a retention amount as a distance apically beyond the height of contour of the one or more teeth of the dentition.
