About this study

Official title: Miniscrew-supported Versus Standard Frog Molar Distalizing Appliances (Clinical Study)

This study aimed to compare the effectiveness and efficiency of miniscrew-supported and standard frog molar distalizing appliances.

Read the detailed description

A prospective randomized clinical trial study was carried out on twenty healthy Egyptian subjects, each required molar distalization as part of their comprehensive orthodontic treatment. The subjects were selected and treated at the outpatient clinic of the Orthodontic Department, Faculty of Dentistry, Ain-Shams University.

The inclusion criteria in this subject selection in this study was as follows;

  1. All the subjects had an age range from 11 to 16 years with a mean of ±13.5 years.
  2. All the subjects had skeletal Class 1 or mild skeletal Class 2 due to maxillary excess.
  3. All the subjects had bilateral Class II molar relationship.
  4. All subjects were free from any dental anomalies.
  5. All subjects had good oral hygiene. The exclusion criteria in this study was as follows; 1- Missing permanent teeth with exception of 3rd molar. 2- Previous orthodontic treatment. 3- Systemic disease that may influence orthodontic treatment and drug intake. 4- Periodontal disease. 5- Functional mandibular deviations and facial asymmetry. 6- History of parafunctional habits.

The subjects were equally and randomly divided into two groups; group A and group B which included ten subjects per group. These groups were classified according to the type of distalizer utilized:

  • Group A: included ten subjects utilizing the conventional frog molar distalizing appliance (CF).
  • Group B: included ten subjects utilizing the Miniscrews-supported frog molar distalizing appliance (MSF)

The pretreatment and post-distalization Database Records All subjects had the following records; a clinical diagnostic sheet, orthodontic study cast (according to ABO index), extraoral and intraoral photographs, and CBCT.

These records were obtained at T1 before distalization and at T2 after distalization.

The study protocol was approved by the local ethics committee, faculty of dentistry, Ain-Shams University. Before commencing with treatment, all the subjects and their guardians received a full explanation of the treatment protocol. After which they were asked to sign a detailed written consent.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing miniscrew-supported Frog molar distalizing appliance and Standard Frog molar distalizing appliance in people with Distalization by Miniscrews, run by Ain Shams University.

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 5 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: finished, as of the sponsor's last update on 4 May 2015. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

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?

mesial migration of anterior teeth measured in millimeter and angles by using cone beam computerized tomography (time frame: 6months). 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 4 May 2015.
