Study Notes

Retention Phase

Retention is the phase of orthodontic treatment that maintains teeth in their corrected positions after active orthodontic tooth movement has stopped.
This phase prevents relapse, which is the return of the original malocclusion features following correction.
Relapse is officially defined by the British Standards Institute as the return of the original malocclusion features.

Post-Treatment Changes

Post-treatment changes refer to any changes in tooth position after the final tooth position at the end of treatment.
These changes may be a return towards the original malocclusion, but can also be caused by growth or ageing, unrelated to the orthodontic treatment.
Post-treatment changes can be in addition to relapse, and are relevant to patients as they affect the final outcome of the treatment.
