ABSTRACT:
An orthodontic appliance has a tooth-abutting surface oriented at an acute angle relative to the base of an arch-wire slot. A lip bumper tube of the appliance is reverse offset relative to the base of the arch-wire slot to obtain more accurate manipulation of the force and torque vectors applied to the tooth. The angle of the base also reduces occlusal interference by gingivally inclining the lip bumper. Wedge-shaped occlusal tie wings further reduce occlusal interference. An auxiliary hook of the appliance is shaped so that its extension in the buccal direction is less than that of the lip bumper tube to reduce patient irritation and discomfort.
