Implants in orthodontics: the impact of new treatment modalities.

The specialty of orthodontics has felt the impact of implant dentistry, but not to the extent that the surgical and restorative specialties have, both of which have undergone dramatic transformation in the last 20 years. However, implant technology has begun to be embraced by the orthodontic community, and not merely for the purpose of tooth replacement. When implants are used for anchorage, orthodontic mechanotherapy is simplified and facilitated. In fact, treatment outcomes not considered possible by conventional means become quite feasible. Other advantages of the inclusion of implants in orthodontic appliance management include decreased treatment time (because en masse movements become possible) and elimination of compliance dependence. These factors all result in more predictable treatment outcomes. Various mechanisms by which implants can be used are available. All fall under the scheme of either "direct" or "indirect" anchorage. It is this author's firm contention that as these strategies become mainstream, many of today's conventional devices designed for anchor preservation will be rendered obsolete.
