Orthodontic Retention In France - ORIF

The goal of this study is to survey retention procedures used by French orthodontists, and evaluate the needs for practice guidelines. The hypothesis is that there is no consensus among orthodontists, requiring practice homogenization via expert guidelines. Similar studies have been driven in others European countries (such as Swiss, the Netherlands, Lithuania and Norway), but not in France.
