About this study

Official title: Effectiveness of Four Mini-screws Supported Hyrax for Maxillary Expansion in Early Adulthood: A Randomized Control Trial

This study aims to evaluate the Skeletal and Dento-alveolar expansion in adult patents using Four Mini-screws Supported Hyrax in compare with untreated control group.

Read the detailed description

Aim of the study: To evaluate the Effectiveness of Four Mini-screws Supported Hyrax for Maxillary Expansion in Early Adulthood

Methodology:

  • Essential record for orthodontic treatment will be taken.
  • impression with bands on upper first molars will be taken.
  • Four eyelets will be soldered to the body of the hyrax appliance (size 10, Dentaurum, Germany).
  • CBCT will be taken while patient wearing 1 mm thickness vacuum on the lower arch to dis-occlude both arches.
  • Delivery, check the retention and fitness of the appliance.
  • The appliance will be cemented using band cement(compomer).
  • Using 3M contra-angle driver, the screws (Tomas screw size 10, Dentaurum, Germany) will be loaded and inserted.
  • Activation of the appliance by opening it two turns immediately, followed by two turns everyday till cross bite correction or appearance of midline diastema.
  • Closure of the device, and leave the appliance in-situ for five months as a retention.
  • Post-expansion CBCT will be taken and continue fixed orthodontic treatment.

Outcome: skeletal and dento-alveolar expansion will be evaluated

What is being measured

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

  1. Skeletal maxillary expansion

    To compare the amount of skeletal expansion pre and post expansion

    Measured: 5 months interval between pre and post-expansion

Secondary outcomes (1)
  1. Dento-alaveolar expansion

    To compare the amount of Dento-alaveolar expansion pre and post expansion

    Measured: 5 months interval between pre and post-expansion

Questions about this trial

What is this clinical trial studying?

A study testing Hybrid hyrax in people with Transverse Maxillary Deficiency, 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 7 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 21 Jun 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?

Results are not available in the source record.

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?

Skeletal maxillary expansion (time frame: 5 months interval between pre and post-expansion). 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 21 Jun 2024.
