Miniscrews are the most important recent innovation in orthodontics and have
won a place, we believe, in the routine appliance design of everyday orthodontic
practice. They are, we think primarily applicable in the treatment of the most
prominent feature of the malocclusions orthodontists regularly confront, an
antero-posterior discrepancy. Accordingly we discuss the protocol for full banded
and bonded Class II mechanotherapy with miniscrew anchorage for:
• Global arch or anterior sectional displacement;
• Direct or indirect mechanics;
• Sliding or loop mechanics.
We then demonstrate clinical procedures: placement of miniscrews, static and mobile sectors, strengthening sectorial anchorage, active forces, and space management.
Next we analyze the mechanics of treating complex cases with vertical as well as antero-posterior problems.
Throughout the article we illustrate the text with sketches and clinical records.
