简要总结

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

详细描述

  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.

结局指标

主要结局

The improvement of lower incisors irregularity using Little Irregularity Index.

时间窗: 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.

次要结局

  • The stability of lower incisor positioning after ending treatment(after 1-3 months)
