About this study

Official title: The Effectiveness of Polyether-Ether-Ketone (PEEK) as a Fixed Retainer Compared to Multistranded Stainless Steel Wires: A Randomized Clinical Trial

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.

Read the detailed 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Multistranded stainless steel fixed retainerDevice

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

  • Polyether-Ether-Ketone (PEEK) fixed retainerDevice

    Polyether-Ether-Ketone (PEEK) fixed retainer is used for orthodontic patient after completion of orthodontic treatment to achieve stability of alignment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

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

Secondary outcomes (4)
  1. Failure rate

    how many times the retainer needed to be replaced or repaired

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

  2. Periodontal health status

    The effect of fixed retainer on the periodontal health is measured by oral hygiene indices

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

  3. Patient satisfaction

    Patient satisfaction concerning esthetics, speech and comfort is obtain by questionnaire.

    Measured: At T1 after one month and T3 after 6 month

  4. 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

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

Questions about this trial

What is this clinical trial studying?

A study testing Multistranded stainless steel fixed retainer and Polyether-Ether-Ketone (PEEK) fixed retainer in people with Retention, run by Esraa Salman Jasim at 1 site in Iraq.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 25 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iraq. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Stability of lower anterior teeth (time frame: T0 is the stating of retention, T1 after one month, T2 after 3 months and T3 after 6 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05557136, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
