Inclusion Criteria: A- leveling and alignment Eligibility criteria 1. Complete permanent dentition (third molars not included). 2. Moderate mandibular anterior crowding (with Little's irregularity index score greater than 4 mm) who required nonextraction approach in the mandibular arch. 3. No tooth size, shape or root abnormalities visible on patient's radiographic records. 4. No spaces in the mandibular arch. 5. No blocked out tooth that did not allow for placement of the bracket at the initial bonding appointment. 6.
