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.
