Question 4

ICON - overview

Answer 4

Each component is scored
Each component has a different weighting to reflect need for treatment
Total of weighted scores=ICON for case
Pre-treatment score=treatment need and complexity
Post treatment score gives acceptability
Pre-treatment-4xpost-treatment=degree of improvement
Is a useful index as it incorporates both patients’ and clinicians’ perceptions regarding orthodontic treatment
ICON alone is not a suitable predictor for appearance, function, speech or treatment need
