Abstract

Miniscrews are the most important recent innovation in orthodontics and havewon a place, we believe, in the routine appliance design of everyday orthodonticpractice. They are, we think primarily applicable in the treatment of the mostprominent feature of the malocclusions orthodontists regularly confront, anantero-posterior discrepancy. Accordingly we discuss the protocol for full bandedand 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.
