Nance

The Nance appliance is a widely used orthodontic device designed to achieve slight expansion or rotation of the upper molars while effectively holding them in place during and after orthodontic treatment. This appliance is particularly valuable for preventing upper molars from drifting forward, maintaining proper occlusion, and ensuring alignment throughout the treatment process. Additionally, the Nance appliance can function as a fixed upper retainer, providing long-term stability for the upper arch after the desired tooth movements have been achieved. It is customizable, allowing for the incorporation of adjustment loops on the wire, which enables orthodontists to make necessary modifications as treatment progresses. With its dual functionality and ability to support molar positioning, the Nance appliance is an essential tool in comprehensive orthodontic care.
