Abstract:
For over a century the complete and long term retention of orthodontic treatment results has been the "Achilles heel" of the orthodontic discipline, regardless of which particular technique was used to treat a given case nor which treatment philosophy spawned its methods. Yes, there are some cases that appear on the surface to remain orthodontically stable, preserving the beautiful results effected by the treating clinician's efforts without exhibiting even the most minuscule post-treatment changes in tooth position.
