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.

The type of anchorage provided by the elastics is known as :
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.
