Correct answer: D — A bonded lingual retainer (fixed retainer wire bonded to the lingual surfaces of the anterior teeth) provides long-term retention without relying on patient compliance
A bonded lingual retainer (typically a multi-stranded stainless-steel or fibre-reinforced composite wire bonded to the lingual surfaces from canine to canine) provides continuous, passive retention without depending on patient compliance (unlike removable retainers). It is the most reliable method for maintaining lower incisor alignment long-term. However, it requires regular monitoring for bond failures, wire fractures, calculus accumulation, and caries. Patients must be instructed on specialised oral hygiene techniques (floss threaders, interproximal brushes) around the bonded wire.
