Acceptability comparison between Hawley retainers and vacuum-formed retainers in orthodontic adult patients: a single-centre, randomized controlled trial

ConclusionsOver a 6-month period of retention, VFR was significantly more acceptable than HR in speech, appearance, gingival irritation, swallowing, self-confidence, and comfort. Subjects in the HR group believed that their retainers were significantly more durable than those in the VFR group at the final assessment. Both retainers were equal regarding fitting of the appliance, biting, and hygiene perception.RegistrationNot registered.ProtocolThe protocol was not published before trial commencement.FundingThis trial was funded by the Saudi Swiss Consultant Dental Centre.
