Acrylic versus Silicone in Interceptive Orthodontics


Abstract:
The purpose of this study was to compare the clinical effectiveness and patient compliance regarding interceptive orthodontics, between a prefabricated functional appliance (PFA) and an Andersen Activator.The PFA appliance used was the TRAINER Systemâ„¢, a flexible appliance made of non-thermoplastic silicone (soft) or polyurethane (hard). The Andersen Activator is a functional acrylic appliance.The sample consisted in 20 subjects (10 girls,10 boys), mean age 10.5 years with a class II division 1 malocclusion and an overjet>6mm. The patients were randomly selected for treatment with either PFA or AA. Overjet, overbite and lip seal were recorded before and every 3 months after the start of the treatment. The treatment was considered finished when the overjet reduced< 3mm. No significant differences were found in overjet and overbite reduction or lip seal between the two groups. The Activator caused less discomfort than the Trainer, and seemed to be more acceptable.
