Inclusion Criteria
- •An age from 12-16 years.
- •Low to average facial vertical pattern.
- •A mild to moderate crowding in mandibular arch with reduced transverse dimension which require non extraction orthodontic approach.
- •Similar amount of crowding on each side of the mandibular arch.
- •No previous orthodontic treatment.
- •Good oral and general health.

- •Severe crowding.
- •Steep mandibular plane.
- •Asymmetric crowding on both sides of the arch.
- •Shifting of mandibular dental midline.
- •Impacted lower 2nd premolar.
Arms & Interventions
william's expander
Eight patients will be treated with William's expander, where the arms of expander will be placed parallel to the line of occlusion at the middle of lingual surface of the anterior teeth with two bands on lower permanent first molars.
Intervention: williams's expander (Device)
self activated leaf expander
Eight patients will be treated by self-activated leaf expander that does not need activation by the patient.
Intervention: self activated leaf expander (Device)
Outcomes
