Concept
"Any treatment procedure which eliminates or reduces the severity of a developing malocclusion, as this may reduce the need for further treatment or make it simpler."
Chung CK & Kerr WJ. 1987 Interceptive orthodontics: application and outcome in a demand population.

Limitation
“ .. Interceptive treatment can be very helpful in reducing the severity of problems, but rarely is so successful that later stages of treatment are unnecessary ! ”
