Prevalence of the use of anchorage miniscrews among French orthodontists

Since always, anchorage has raised frequent problems for orthodontists. Since the early 2000s, the use of anchorage miniscrews has spread on a vast scale among practitioners. For the first time, a broad epidemiological survey (733 exploitable responses) has looked into the habits of French orthodontists regarding the use of anchorage miniscrews. The survey reveals that the majority of French practitioners have adopted miniscrews in their daily practice (66%), particularly among those using the lingual technique. However, the number of patients concerned still remains small for most practitioners (fewer than 10 patients for 65% of users). Seventy-four percent of users are satisfied with their experience with miniscrews although a majority uses them exclusively in adults (64%). The movements most sought by miniscrew users are mesialization/distalization and intrusion/extrusion. Among non-users, 60% have never placed an anchorage miniscrew but are thinking about doing so, whereas 20% of practitioners have used them but have since abandoned them. Finally, 20% of non-users have never used anchorage miniscrews and do not intend to do so.
