ABSTRACT:
A rigid buccally positioned bar, placed above the upper teeth and stabilized anteriorly by a connector to a protruding bony anchor carries a variety of force systems to facilitate tooth/teeth movement in all three spatial directions. The bar can be stabilized posteriorly by insertion into tubes on the molar bands. Various attachments connect different teeth to the buccally positioned bar for exerting the desired forces on the teeth.
