Modern Ortho Lingual Sheaths

Lingual sheaths on molar bands are used to hold wires from removable appliances like Nance , transpalatal expanders, lower lingual arches, and other appliances.

Each sheath usually has an indentation on the distal end that serves as a catch to prevent the archwire from slipping out. However, frequent insertion, removal, and manipulation of the wire causes the dimple to flatten and allows the archwire to loosen or fall out. Even tying the wire in with a stainless steel ligature is not a failsafe method, and the ligature can be irritating to the tongue and soft tissues

With the following technique, the clinician can adjust the lingual sheath at every appointment. The only tool needed is a band seater with a plunger that is pulled back toward the handle and let go, pushing the tip forward
