Abstract :
Anchorage in orthodontics is one of the most important consideration during extraction treatment planning. Unwanted movement of molars in extraction space is called anchorage loss. Anchorage loss can be assessed by Cephalometrics but superimposition is one of the main disadvantages of this method. Thus, in this article we used a modified “Nance palatal arch" which helps to assess anchorage loss during different stages of treatment.
