About this study

Official title: The Effect of Multiple Injections of Platelets Rich Fibrin (i-PRF) on The Rate of Canine Retraction A Split-mouth: A Randomized Controlled Trial

this clinical trial aims to prove that multiple injections will produce a steady rate of acceleration of orthodontic tooth movement.

Read the detailed description

Platelet-rich fibrin injection is a second-generation platelet concentrate, prepared from centrifuged blood which is a rich source of platelets, stem cells, and growth factors seven times greater than that released by platelet-rich plasma. It is a simplified procedure with no biochemical manipulation of blood, free from anticoagulants which are known to inhibit wound healing or any gelling agent, and easily usable with a low rate of mistakes during the preparation procedure.

A variety of growth factors are released by PRF such as platelet-derived growth factor (PDGF), transforming growth factor β (TGF-β), and vascular endothelial growth factor (VEGF), which play a crucial role in angiogenesis, collagen synthesis, and bone regeneration.

Treatment with extraction especially in adult patients may take a longer time due to reported increase in bone density and lower bone regenerative rate. Also, the retraction process to close extraction spaces most of the time is accompanied by bone loss and root resorption as reported in the previous studies. i-PRF can accelerate tooth movement, in addition, prevent tooth retraction undesirable side effects.

  • Injectable platelet rich fibrin (i-PRF): in acceleration of orthodontic tooth movementProcedure or surgery

    Also called The effect of autologous platelet concentrates on orthodontic tooth movement

    Preparatory phase

    • Space closure will be done on a 17x25 stainless steel wire
    • Both molars will be indirectly anchored to the miniscrew
    • Extend closing coil spring of suitable length from the canine hock to the first molar hock for retraction.
    • Apply a force of 150gm for each side. The force is measured by a force gauge and activated each visit to keep it constant all over the retraction phase. PRF Injection protocol
    • The First injection will be 3 weeks before extraction
    • By the end of the fourth week the patients will be referred for pre-intervention records. Upper arch CBCT will be obtained to take preintervention measurements of the alveolar bone.
    • At the time of canine retraction patient will receive another injection immediately and an alginate impression will be taken
    • follow up every month and injection will be repeated month after month with an observational period of 5 months.
Study groups in NCT05766618
Study groupRoleWhat they receive
injection siteExperimentalit is the arm where the patients will receive the PRF injection intraligamentally in distobuccal, and distopalatal areas of the distal surface of the canine also submucosal injection will be given buccally and palatially (0.25mm) for each side in either the right or left side of the arch.
Receives: Procedure: Injectable platelet rich fibrin (i-PRF): in acceleration of orthodontic tooth movement
control siteNo interventionit is the arm where the patients will not receive any injection with the same method of retraction as the intervention side.

What is being measured

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

  1. Rate of canine retraction.

    Rate of orthodontic tooth movement will be measured by calculating the difference in the canine position in mm throughout digital superimposition of consecutive digital models that will be made every four weeks.

    Measured: 5 months

Secondary outcomes (1)
  1. 1. Assess bone level between intervention and control side.

    1. bone level between intervention and control side will be assessed through pre and post retraction CBCT for the upper arch.

    Measured: bone level will be measured at the beginning of the study (T1) and by the fifth month of the study (T5)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Injectable platelet rich fibrin (i-PRF): in acceleration of orthodontic tooth movement in people with Platelet-Rich Fibrin and Acceleration, run by Cairo University at 1 site in Egypt.

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 5 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 13 Mar 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 Egypt. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact Mohamed M Alkhawaga, BDS (+201099345694, mohamed.mamdouh@dentistry.cu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of canine retraction. (time frame: 5 months). 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 NCT05766618, which also lists 31 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2023.
