•All patients should fulfil these inclusion criteria:
•i)Orthodontic patients requiring first upper premolars extraction and two-step retraction technique
•ii)Complete permanent dentition (except third molars)
•iii)No previous orthodontic treatment
•iv)Healthy patients without systemic diseases that can affect bone and tooth movement
•v)Good oral hygiene and healthy periodontium which will be evaluated clinically (probing depth Ã¢â?°Â¤3 mm), with no radiographic evidence of bone loss, plaque and gingival index Ã¢â?°Â¤1 according to Loe and Silness.

•EXCLUSION CRITERIA
•i)History of long term medication will be excluded because nonsteroidal anti-inflammatory drugs and hormone supplements interfere with bone metabolism.
•ii)Those with unilateral chewing or any parafunctional habits, skeletal crossbite or occlusal interferences.
•iii)Periodontally compromised patients because poor bone quality can affect orthodontic tooth movement and development of any mobility during the course of treatment can lead to incorrect measurement of orthodontic tooth movement.
•iv)Impacted canines and canines with dilacerated roots can make orthodontic tooth movement difficult with a high possibility of root resorption.
