The Morelli Bondable Eruption Hook is a traction accessory for the orthodontic management of impacted teeth. It combines a nickel-free stainless steel bondable hook with a factory-assembled stainless steel chain, delivering a ready-to-use traction element that is bonded to the exposed crown and ligated to the archwire for progressive, controlled eruption.
Key Features
Pre-assembled traction chain — bonded and ligated in a single step, with no chairside chain fabrication
Welded chain links — secure link-to-link connection under continuous traction load
Reduced-diameter links — slimmer chain profile for greater patient comfort
Thin, easy-to-cut links — the chain is trimmed chairside to the length each case requires
Nickel-free stainless steel hook — biocompatible option for nickel-sensitive patients
Flat sandblasted base — mechanical retention for direct bonding with orthodontic resin

Clinical Applications
Traction of impacted canines after surgical exposure, with the chain ligated to the archwire
Guided eruption of unerupted teeth under progressive, controlled force
Closed-eruption surgical technique, where the chain runs beneath the repositioned flap
Measurable extrusion control — as the impacted tooth extrudes, the chain links progressively appear in the mouth, and simply counting the exposed links lets the clinician identify how much movement has occurred and where the tooth currently is
Need traction ready to use at the chair?
The chain arrives already assembled and welded to the hook, so the only chairside steps are bonding, trimming and ligating — a ready-to-use traction assembly for impacted tooth mechanics.
