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.
It is a multicenter randomized clinical trial with two arms parallel group. The patients will be randomly divided into two groups, group one: multistranded stainless steel fixed retainer will be used while, and group two PEEK fixed retainer will be used. An intra-oral scan, intra-oral swap and periodontal indices will be taken before starting the treatment (T0), after one month (T1), after 3 months (T2), and after 6 months (T3). Patient perception concerning the fixed retainer will be taken for the patients.

RECRUITINGStability 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.
Time frame: T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month
Failure rate
how many times the retainer needed to be replaced or repaired
Time frame: T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month
Periodontal health status
The effect of fixed retainer on the periodontal health is measured by oral hygiene indices
Time frame: T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month
Patient satisfaction
Patient satisfaction concerning esthetics, speech and comfort is obtain by questionnaire.
Time frame: At T1 after one month and T3 after 6 month
Biohostability
studying the microbial colonization on the retainer wire by using oral swap of fixed retainer and measure total bacterial count (Aerobic and Facultative Anaerobic) on Blood agar, Total streptococcus count and total lactobacillus count on selective media
Time frame: T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month
