Abstract: Aspects of the present disclosure relate to a method and system of determining a first force vector of a selected point in a first position on a virtual dentition of the oral cavity based on the first aggregate force characteristic of a force member, having multiple segments, in the first configuration and determining a second force vector of the selected point in a second position on the virtual dentition based on the first aggregate force characteristic of the force member in the first configuration. The method includes determining a condition of whether the second force vector (or force magnitude thereof) is within 90 percent of the first force vector (or force magnitude thereof) at 50 percent of displacement between the first position and the second position and performing an operation based on the condition.

Abstract: An orthodontic palatal expander may include a first shell configured to receive at least one tooth of a first posterior segment of a dental arch of a patient; a second shell configured to receive at least one tooth of a second posterior segment of the dental arch; and a split beam connected between the first shell and the second shell. The split beam may include a first beam comprising a relatively high modulus material, a second beam comprising the high modulus material, and a region between the first beam and the second beam.

Abstract: A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

Abstract: A removable dental appliance may include an appliance body at least partially surrounding two or more teeth of a patient. The appliance body may include a first shell shaped to receive a first tooth; a second shell shaped to receive a second tooth; and at least one spring bellows that includes an arcuate displacement extending over and away from at least a portion of an interproximal region between the first tooth and the second tooth to join the first shell and the second shell. The spring bellows is configured to apply a force between the first shell and the second shell to cause movement of at least one of the first tooth and the second tooth toward a desired position when the removable dental appliance is worn by the patient.

Abstract: A flexible hook hanger comprises an elongate sheet of pliable backing, an adhesive layer and a hook element. The backing comprises first and second ends, a first zone positioned adjacent the first end, a second zone positioned adjacent the second end and a central zone positioned between the first and second zones. The adhesive layer is disposed on one side of the backing. The hook element is connected to the central zone. In one embodiment, the pliable backing comprises microstructured tape, and the adhesive layer comprises a pressure sensitive adhesive composition comprising one or more hydrocarbon block copolymers, and a polar phenolic tackifier. In another embodiment, at least one of the first and second zones includes a peel arrestor. For example, the first zone and the second zone have a first width and a second width, respectively, and the central zone has a third width that is less than at least one of the first width and the second width.
