Stop Tube Closed is a type of orthodontic accessory used to control the movement of teeth during treatment. It is a small, cylindrical device made from stainless steel that is placed on an archwire to prevent the wire from sliding through a bracket or tube.
The Stop Tube Closed is designed to fit onto a specific size and type of archwire, and is typically used in conjunction with other orthodontic appliances such as brackets, bands, and springs. By limiting the movement of the archwire through a bracket or tube, the Stop Tube Closed can help to control the direction and speed of tooth movement.
