An appliance worn outside of the mouth to provide traction for growth modification and tooth movement.
A wire appliance used to move the lower molars back and the lower front teeth forward, creating room for crowded front teeth. The lip bumper is an internal wire bow that attaches to the buccal tubes on the cheek side of the lower molar bands inside the mouth. The front portion of the bow has an acrylic pad or bumper that rests against the inside of the lower lip. The lower lip muscles apply pressure to the bumper creating a force that moves the molars back.
