The Morelli Bondable Buccal Tubes .022 Roth Simple Passive Self-Ligating use a Nitinol passive clip that closes the slot without pressing on the wire, keeping friction low at the molar. Produced in MIM stainless steel with a Big Foot base, with values supplied for both the upper and lower molars.
Key Features
Passive Nitinol clip for low-friction posterior mechanics
No ligature needed — the clip retains the archwire
Big Foot base for adaptation and bonding stability
MIM stainless steel for dimensional accuracy and strength
Simplified archwire insertion at the back of the arch

Clinical Applications
Low-friction molar anchorage in self-ligating mechanics
Space closure by sliding, where posterior friction matters most
Cases where ligating the terminal molar is impractical
Why a Self-Ligating Tube?
The molar is the hardest point in the arch to ligate cleanly. A passive clip removes that step and the friction that comes with it. Note the values differ by arch: −10° upper against −25° lower.
