3M Unitek Lingual Sheaths, Horizontal and Vertical
Orthodontic lingual sheaths in horizontal and vertical styles, with a two-point contact design that eases lingual archwire insertion and stability.
3M Unitek Lingual Sheaths are orthodontic attachments bonded or banded to the lingual surface of teeth, used to hold lingual archwires in place as part of lingual orthodontic treatment, where appliances are placed on the tongue side of the teeth rather than the more visible facial surface. The range includes a variety of horizontal sheath styles along with one vertical style, with the vertical option featuring a two-point contact design intended to make lingual archwire insertion easier and more stable for the clinician during adjustment appointments.
All of the horizontal styles are available with or without mesial and distal hooks, and with either a solid or slotted tube design, along with an option for a distal latching indent, giving orthodontists flexibility to select the specific sheath configuration that best suits their preferred lingual technique and case requirements.
Lingual sheaths like these are typically bonded to molars as anchorage points for the lingual archwire, playing a similar structural role to buccal tubes in conventional labial orthodontic treatment but positioned on the opposite surface of the tooth. Practices offering lingual orthodontic treatment as an esthetic alternative to visible labial appliances rely on a well stocked range of sheath styles like this to accommodate different case designs.
