Streamlined lingual sheaths feature a variety of horizontal styles and one vertical style with a two-point contact for ease of lingual archwire insertion and stability. All horizontal styles are available with or without mesial/distal hooks; with solid or slotted tube; with or without distal latching indent.
All styles are narrow in the occlusalgingival dimension and have mesial/distal welding flanges that are curved slightly for better adaptation to bands.
