Clinical Trial Summary

this study aim to evaluate the multi-looped lingual retainer activated by a new method to relief the anterior crowding

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The improvement of lower incisors irregularity using Little Irregularity Index.	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.	follow-up three to six months
Secondary	The stability of lower incisor positioning after ending treatment	using multi-looped as a retainer for stability to prevent the relapse after end treatment and the amount of lower incisor irregularity will be evaluated on scanned post-treatment digital models and measured on the 3-shape software.	after 1-3 months
