Abstract: A high-strength, self-ligating appliances with orthodontically desirable dimensions. The appliances incorporate a door slidably engaged to a channel in the body; one that can be opened or closed depending on the equilibrium position of an integral protrusion on the door. Cooperating grooves and rails on the body and the door can guide the door between the open and closed positions, and mitigate against unintentional detachment. Appliances including rails that result in improved labial pull strength are disclosed.

Abstract: A method of forming an optical film results in a film having a useful central 60% portion with a caliper variation of about 5% or less of an average thickness of the film. The method includes selecting a draw ratio λ in a first in-plane stretch direction, setting an effective draw gap defined by a length L and a width W, and stretching a polymer film at the draw ratio and effective draw gap. The effective draw gap is set such that the stretching step fits into one of two regimes, the first regime referred to as a uniaxial regime and characterized by a β equal to or less than about 1.0; and the second regime referred to as a planar extension regime and characterized by a β equal to or greater than about 10.0. The disclosure also describes an optical film formed by the method.
