NCT05557136

Brief Summary

A randomized clinical trial is set out to compare the effectiveness of two types of fixed retainer (multistranded stainless steel and PEEK types) in maintaining the stability of lower anterior teeth with less failure rate.

Outcome Measures

Primary Outcomes (1)

  • Stability of lower anterior teeth

    The effectiveness of PEEK retainers as compared to a dead-soft multi-stranded stainless-steel wire in maintaining alignment of the lower anterior teeth in terms of Little's irregularity index.

    T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month

Secondary Outcomes (4)

  • Failure rate

    T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month

  • Periodontal health status

    T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month

  • Patient satisfaction

    At T1 after one month and T3 after 6 month

  • Biohostability

    T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month

Study Arms (2)

Multistranded stainless steel fixed retainer

EXPERIMENTAL

Multistranded stainless steel fixed retainer is used for lower anterior teeth (canine to canine) to maintain the stability of teeth after completion of orthodontic treatment

Device: Multistranded stainless steel fixed retainer

Polyether-Ether-Ketone (PEEK) fixed retainer

EXPERIMENTAL

Polyether-Ether-Ketone (PEEK) fixed retainer is used for lower anterior teeth (canine to canine) to maintain the stability of teeth after completion of orthodontic treatment

Device: Polyether-Ether-Ketone (PEEK) fixed retainer

Interventions

Multistranded stainless steel fixed retainer is used for orthodontic patient after completion of orthodontic treatment to achieve stability of alignment.
