Bonded Retainer
A fixed wire retainer bonded directly to the lingual surface of teeth to prevent post-treatment tooth movement without patient compliance.
Full Definition
A bonded retainer, also called a fixed or lingual retainer, consists of a thin twisted or braided stainless steel or fibre-reinforced composite wire attached to the inner (lingual or palatal) surface of the teeth with dental adhesive. It is placed at the end of active orthodontic treatment and is designed for long-term or permanent retention. Because it does not rely on patient compliance, it is particularly favoured for the lower anterior region. Editors should note the hyphenation: 'bonded retainer' is two words and unhyphenated; distinguish from 'bonding,' which refers to the process of attaching brackets.
Usage
Usage note: Do not confuse with the verb 'bonding', which describes bracket placement. The noun phrase is 'bonded retainer' (no hyphen).
