"A Lower Lingual Holding Arch appliance consists of a wire running around the inside of the lower dental arch cemented to the lower molars with bands. This wire acts as a bumper, preventing the molars from moving forward after baby teeth fall out and leaving space for permanent teeth to erupt. This appliance can help prevent crowding and other problems."
