About

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.

Full description

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.
