An 18 year old female patient reports for her routine orthodontic appointment. 1st premolars from all quadrants had been extracted at the beginning of treatment. Her current status reveals 3 mm of space between the canines and 2nd premolars in all quadrants. Class II elastics were initiated to close these spaces. The type of anchorage provided by the elastics is known as :
Intramaxillary anchorage
Baker’s anchorage
Moyer’s anchorage
Absolute anchorage
In 1893, Henry A. Baker introduced intermaxillary rubber bands to correct protrusions. His method came to be known as “Baker anchorage.” Class II elastic acts to correct a Class II relationship by providing a retraction force to the upper anterior teeth and a simultaneous protraction force to the lower molars.
