Abstract
Abstract A muscular expansion bumper appliance is optionally removable from a patient's mouth and includes a wire form member formed in a U-shape with the free ends which may be removably secured to buccal tubes. The wire form member supports at least one side pad which overlies one or both of the upper or lower posterior teeth to hold the user's cheeks away from those teeth to permit lateral posterior expansion. The side pads can be trimmed to custom fit the appliance to the user and the appliance comes in varying sizes.
