About this study

Indirect anchorage (In-A) has been broadly used for anchorage reinforcement during anterior segment retraction. The study compared between the efficacy of rigid vs non-rigid connections of In-A i during upper canine retraction in dentoalveolar protrusion cases

Read the detailed description

Fifteen female patients with dentoalveolar protrusion were included in this study. A miniscrew was inserted following levelling and alignment between the upper first molar and second premolar of both sides. Randomization was applied before first premolar extraction where one side of the arch received a rigid indirect anchorage connection (Group I) of 0.019 x 0.025-inch stainless steel (St.St) archwire from the miniscrew to the auxiliary tube of the upper first molar band, and the other side received a non-rigid indirect anchorage connection (Group II) of 0.014-inch St.St ligature ligating the upper second premolar to the miniscrew. Canine retraction was performed on 0.017 x 0.025-inch St.St archwire applying 1.5 N retraction force. The duration of the study was 7 months. Data was collected from digitized models where anchorage loss of the upper first molar relative to the frontal plane and the vertical position of the upper second premolar were measured

Being tested
non rigid indirect anchorage connection, rigid indirect anchorage connection

What participants receive

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

  • non rigid indirect anchorage connectionProcedure or surgery

    a nonrigid connection is placed between the miniscrews and the second premolar to prevent mesial tooth movement.

  • rigid indirect anchorage connectionProcedure or surgery

    a rigid connection is placed between the miniscrews and the first molar to prevent mesial tooth movement.

Rigid ConnectionActive comparatorrigid wire 19 x 25 inch stst wire was place between upper first molar and the miniscrew placed between the first molar and second premolar
Receives: Procedure: rigid indirect anchorage connection

What is being measured

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

  1. anchorage loss

    amount of anchorage loss of the upper first molar during canine retraction using digital model in mm.

    Measured: 4 month

Secondary outcomes (1)
  1. vertical position of the upper second premolar

    The secondary outcome was to assess the change in the vertical position of the upper second premolar following canine retraction using indirect anchorage using digital models in mm.

    Measured: 4 month

Questions about this trial

What is this clinical trial studying?

A study testing non rigid indirect anchorage connection and rigid indirect anchorage connection in people with Orthodontic Appliance Complication, 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 1 inclusion and 1 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: finished, as of the sponsor's last update on 15 Aug 2024. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

anchorage loss (time frame: 4 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Aug 2024.
