Summary

Introduction

Orthodontic treatments apply forces on teeth to move them. Since there is no fixed anatomic anchorage, every orthodontic action will cause a counter-action of equal force. This is usually unwanted and strong bone anchorage is used to prevent this counter-action. These anchorages provide the fixed point required for orthodontic effectiveness.

Technique

We describe some devices, their implantation site, placement, and removal. Our experience is essentially based on the Lomas^庐 and Orthocorrect^庐 devices manufactured by Mondeal^庐 (Germany) and on screwed anchorage devices manufactured by Stryker^庐 (USA).

Discussion

These screwed anchorage systems allow for previously impossible treatments, especially for orthodontics applied to adults and for preprosthetic orthodontics. But these screws can induce apical migration of teeth; so it may be necessary to provide several anchorage sites. Complications are rare and usually present as root perforation.
