About this study

  • patients preparation( photo- impression- x-ray- scan the lower cast to calculate the crowding )
  • The multi-looped lingual retainer was fabricated on the patient's lower cast
  • 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.
  • the bonding agent was applied on such surfaces after a good isolation and was light-cured for 20 seconds.
  • 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.
  • follow-up the patients * Outcomes: The improvement of lower incisors irregularity using Little Irregularity Index.

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.

Treatment and study plan

multi-looped wire

Other

using multi-looped wire as a retainer

Primary outcomes

  1. 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

  1. The stability of lower incisor positioning after ending treatment

    Time frame: 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.
