INTERCEPTIVE ORTHODONTICS

• The phase of the science and art of orthodontics employed to recognise and eliminate potential irregularities and malpositions of the developing dento‐facial complex.

• Serial extraction

• Correction of developing cross bite

• Control of abnormal habits

• Space regaining

• Muscle exercises

• Interception of skeletal mal relation

• Removal of soft tissue or bony barrier to enable eruption of teeth 9

Serial extraction

• Early mixed dentition period

• Planned extraction

• Orderly sequence and pre‐determined pattern

history

• KJELLGREN – 1929 ; coined

• NANCE – 1940; popularized – “planned & progressive extraction”

• HOTZ – 1970 – “active supervision of teeth by extraction”.

rationale

• Arch length – tooth material discrepancy

• Physiologic tooth movement
