Challenging task- Unwanted tooth movements in-spite of orthodontic retainers
According to a recent study, researchers have observed that unwanted tooth movements occurred in patients with fixed retainers post orthodontic treatment . This was seen to be more in maxillary arch than with respect to the mandibular retainers.
The study is published in the BMC Oral Health Journal.
To prevent relapse tendencies and aging processes in orthodontic treatments, lifelong retention seems to be necessary and also poses as a long term challenging task in orthodontics. Recently, reports of unwanted tooth movements despite intact orthodontic bonded retainers have increased. These movements are not subject to relapse but are classified as a new developed malocclusion.
Katharina Klaus and associates from the Department of Orthodontics, Justus-Liebig-University Giessen, Schlangenzahl, Giessen, Germany aimed to analyze the prevalence of unwanted tooth movements despite intact bonded cuspid-to-cuspid retainers and to identify possible predisposing factors.
They assessed plaster casts of all patients finishing orthodontic treatment during three consecutive years before treatment(T0), after multibracket appliance debonding (T1) and after two years of retention (T2).
