Overview
Brief Summary
this study aim to evaluate the multi-looped lingual retainer activated by a new method to relief the anterior crowding
Detailed Description
1. patients preparation( photo- impression- x-ray- scan the lower cast to calculate the crowding ) 2. The multi-looped lingual retainer was fabricated on the patient's lower cast 3. The lingual surfaces of teeth were etched with 35% phosphoric acid for 20 seconds The multi-looped lingual retainer was activated in the new way (Kattan method ) by tightening a steel ligature wire 0.010 inches, to the reinforcement 0.020-inch stainless steel arch-wire. 4. the bonding agent was applied on such surfaces after a good isolation and was light-cured for 20 seconds. 5. A flowable composite resin was applied. After checking its fit on the surface of the teeth, The lingual wire was bonded with a drop of flowable composite resin and was light-cured for 20 seconds. 6. follow-up the patients \* Outcomes: The improvement of lower incisors irregularity using Little Irregularity Index.

Eligibility Criteria
Inclusion Criteria
- •Adult male and female patients, the ages of 16 to 25, the patients having class I canine with mild to moderate lower incisors crowding
- •good oral hygiene.

- •Facial trauma, Oral habits such as onychophagia, pen biting, and tooth mobility.
Outcomes
Primary Outcomes
The improvement of lower incisors irregularity using Little Irregularity Index.
Time Frame: follow-up three to six months
using multi-looped for relief crowding, the digital model analysis will be used to calculate the amount of irregularity by using Little Irregularity Index .the measurement will be done on 3-shape software.
Secondary Outcomes
- The stability of lower incisor positioning after ending treatment(after 1-3 months)
