The Morelli Bondable Concave Lingual Button is a stainless steel orthodontic attachment bonded directly to enamel with adhesive resin, creating a fixation point for rotation, traction, retraction and anchorage mechanics. Its mushroom-shaped head traps elastics and ligature wires, and its concave base is dished inward to seat over convex enamel surfaces.
Key Features
Concave bonding base — the dished curvature wraps onto convex enamel surfaces
Micropins retention pattern — mechanical anchoring for the bonding adhesive
Mushroom-shaped head — traps elastics and ligature wires so the auxiliary does not slip off
Stainless steel body — corrosion-resistant metal construction for direct bonding
Accepts springs, wires and elastic ligatures for traction and tooth movement
Rounded shape with optimal finishing for comfort on the lingual surface

Clinical Applications
Bonding on convex enamel surfaces, where the dished base follows the bulge of the crown
Rotation and derotation mechanics with elastic chain or ligature wire running from the button to the archwire
Traction and retraction with elastics or springs anchored on the bonded button
Does the base match the crown curvature?
This button is bonded straight to the tooth with adhesive resin: the concave Ø3.5 mm base with its micropins pattern is dished to follow convex enamel, and the mushroom head then holds elastics, ligature wires or springs. Ten pieces per package.
