3M Unitek Level Anchorage Palatal Bar, Sized
A palatal bar appliance that gives additional molar support during facebow wear, supplied across several sizes to match different arch widths.
The Unitek Level Anchorage Palatal Bar is an appliance fitted across the palate and attached to the molar bands, used specifically to provide additional support and stability to the molars during periods when a patient is wearing headgear with a facebow. Facebow forces are applied to the molars through the inner bow of the headgear appliance, and without additional support the molars can be prone to unwanted tipping or rotation under that extraoral force over the course of treatment.
By linking the two molars together across the palate, a level anchorage bar helps distribute and stabilise the force more evenly, supporting the anchorage strategy the orthodontist has planned around facebow or headgear wear. This bar is supplied in several sizes, reflecting the natural range of palatal widths seen across different patients, so the clinician can select the closest fitting size rather than needing to hand-adjust a single generic bar significantly.
Practices that prescribe headgear and facebow wear as part of their anchorage protocol keep a stock of palatal bars in different sizes to support that treatment approach whenever additional molar stability is needed during the period of extraoral force application.
