Using Multi-looped Lingual Retainer to Relief Anterior Mandibular Crowding

Completed

• Conditions: Crowding of Anterior Mandibular Teeth

• Registration Number: NCT06337435
• Lead Sponsor: Cairo University

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.

Primary Outcome Measures

Name	Time	Method
The improvement of lower incisors irregularity using Little Irregularity Index.	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 Outcome Measures

Name	Time	Method
The stability of lower incisor positioning after ending treatment	after 1-3 months	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.
