3. Extraction of second molars
1997 JCO, Efthimia K. Basdra, Gerda Komposch.
Advantages:
• Significant reduction in treatment time and appliance use
• Faster and less problematic distalization of upper first molars
• More promotion of bite opening
• Less adverse effect on profile
• More ease and predictability of upper third molar eruption
Disadvantages include:
• More loss of tooth substance
• Increased distance of extracted teeth from location of crowding
• Increased tendency of lower second molars to overerupt
• More need for patient cooperationwww.indiandentalacademy.com

4. • Second molar extractions, open the bite.
• Premolar extractions closes the bite.
• Maxillary second molars are not often extracted in place of the more
usual premolars. However, Graber recommends this approach in Class
II, division 1 cases with excessive labial inclination of the maxillary
incisors, no anterior spacing, minimal overbite, and upper third molars
in good position.
• Jarabak suggests second molar extraction for non-skeletal Class II
patients with a distinct horizontal, counterclockwise growth pattern.
• Rees and Witt indicate removal of the upper second molars in Class II
cases with deep bite and a well-formed lower arch.
