Extraction in Orthodontics

General guidelines about extraction based on classification of occlusion.

Extraction varies case to case , but in more than 80% of cases, we follow same guidelines.

Class 1 bimax and cases with severe crowding - All 4 1st premolar extraction.

Class 2 div 1 - Maxillary both 1st premolar extraction. OR
Upper both premolar and one lower incisor. {Central or lateral incisor.}

Class 2 div 2 - Most of the time,ni extraction requires.

Class 2 div 1 subdivision - Maxillary both premolar extraction and lower premolar extraction on the side of class 1.

Class 2 div 2 subdivision - No extraction.

Class 3 .-
It is based on severerity of malocclusion.
Mild cases requires one lower incisor extraction.
Class 3 bimax requires all 4 premolar extraction.
For severe class 3, orthognathic surgery is needed.


Note - These are just to help you to get a rough idea about extraction in orthodontic. It's no way a blueprint for case management.
