The Morelli Bondable Double Buccal Tubes .022 MBT Convertible for the lower first molars combine a main archwire tube with an auxiliary tube for additional mechanics. Produced in MIM stainless steel, the tube has a low profile, rounded surfaces and an anatomical base, and the cap can be removed to convert it into a bracket.
Key Features
Double tube — main archwire plus an auxiliary channel
Convertible cap turns the tube into a bracket when needed
MIM stainless steel for dimensional accuracy and strength
Angled horn-shaped entry eases archwire insertion
Support groove and anatomical base for accurate placement
