The Morelli Weldable Lingual Button is a stainless steel orthodontic accessory fixed by welding to orthodontic bands, creating a fixation point on the lingual or palatal surface for tooth movement. It is used in rotation, traction, retraction and anchorage systems, and its mushroom-shaped head traps elastics and ligature wires while also accepting springs for controlled force application.
Key Features
Welded fixation — attached directly to orthodontic bands, with no bonding resin involved
Stainless steel construction — alloy suited to welding onto stainless steel bands
Mushroom-shaped head — traps elastics and ligature wires so the auxiliary does not slip off
Round Ø4.5 mm base — contact area for welding the button to the band
Accepts springs, wires and elastic ligatures for traction and tooth movement
Rounded shape with optimal finishing for patient comfort on the lingual surface

Where does this button attach?
This button is fixed by welding: the round Ø4.5 mm base is joined to an orthodontic band, not to enamel, and the mushroom head then holds elastics, ligature wires or springs for rotation, traction, retraction and anchorage. Ten pieces per package.
