Quantum™ Direct Bond Composite Roth Brackets Like metal brackets, Quantum brackets bond and debond quickly, are easy to ligate, and feature wide, shatter-resistant hooks. Unlike metal, they don’t conduct cold temperatures and are less irritating. Like other composite brackets, Quantum is smooth and comfortable and won’t stain or discolor. Unlike others, Quantum is a cast bracket which doesn’t easily degrade or distort under ligation or archwire pressure. Requires plastic primer (
MO4000803) for bonding.
