Retention and relapse

BDS coreOrthodontics

Teeth can move after active treatment. Explain retention type, duration, upkeep and the possibility of relapse before treatment.

On this page
01

Understand

Retention is required because periodontal and soft tissue adaptation is incomplete and natural tooth movement continues. No method makes relapse impossible.

02

Assess

Discuss bonded and removable retainers, their upkeep, failure signs and long-term wear before treatment starts.

03

Apply

Record a retention plan and responsibility for review. A broken bonded retainer or lost removable retainer needs timely assessment to limit movement.

04 / A CLOSER LOOK

Key distinctions

Relapse risk comes from periodontal fibre rearrangement, continued growth and ordinary lifetime tooth movement. Bonded retainers can fail unnoticed at one tooth; removable retainers can be lost or unworn. A retention plan should include how long to wear, how to clean, what failure looks like and who to contact promptly.

05 / IN PRACTICE

Think through a case

A bonded retainer detaches at one tooth and the patient notices movement. Prompt assessment can prevent more substantial relapse.

06 / EXAM PITFALL

The distinction to remember

Do not discuss retention only at the debond appointment; it should be part of consent from the outset.

07

Test your recall
