About this study

The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place.

The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.

Read the detailed description

The study design of this research project involves recruiting orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. The participants will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one or two night study period. The purpose of the Medibyte monitor is solely to provide a calibrated value of AHI. The Medibyte monitor will not be utilized for investigations and/or treat, cure, mitigate a medical condition. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place.

The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed providing a baseline value and post orthodontic movement AHI value. Additionally the patients arch width, length and other orthodontic measurements will also be taken both from their 3-D dental models and also their 2-D lateral cephalogram x-ray all of which are part of the routine orthodontic records (the x-rays will be taken regardless of the patients participation in the study since they are a required component of the orthodontic records taken at HSDM). The values obtained from the patients casts, lateral cephalogram and Medibyte AHI values will be analyzed both pre-orthodontic appliance cementation and also post tooth movement. The changes, if any, in the dental parameters as compared with the AHI values will allow the investigation of the orthodontic effects of expanding the maxilla, moving the front teeth either forwards or backwards which in effect cause changes to the airway and its effect on AHI values during sleep. In addition to the measurements taken intra-orally, surveys will also be undertaken to study any changes the patients may experience in their sleep and quality of life. If the Medibyte shows a severe reading for obstructive sleep apnea, these patients will then be referred to a sleep specialist for further more conclusive testing.

What participants receive

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

  • Medibyte Portable MonitorOther

    Patients will be provided with the portable monitor in order to measure their apnea/hypopnea index.

What is being measured

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

  1. Relationship between dental movements and AHI

    This outcome aims to measure any changes in the dental measurements such as arch length, arch perimeter, inter-canine and inter-molar changes on the AHI value.

    Measured: 2 Year

  2. Relationship between skeletal changes and AHI

    This outcome aims to measure any changes in the skeletal changes such as SNA, SNB, ANB etc. as measured by the lateral cephalogram and any changes in the AHI

    Measured: 2 Year

  3. Relationship between airway cephalometric changes and AHI

    This outcome aims to measure any changes in the airway cephalometric measurements such as the upper/middle/superior airway space etc. and the AHI

    Measured: 2 Year

Secondary outcomes (1)
  1. Relationship between the changes in the reported quality of life measurements and the AHI

    This outcome aims to measure any changes in the reported quality of life measurements as measured by questionnaires such as conners, epworth, pediatric quality of life and pediatric sleep quesitonnaire and the AHI vale.

    Measured: 2 Year

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea and Orthodontic Tooth Movement, run by Harvard School of Dental Medicine at 1 site in United States.

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 3 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 11 Sep 2018. 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 United States. 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?

Contact Shaima Tabari (415-851-0166, shaima_tabari@hsdm.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relationship between dental movements and AHI (time frame: 2 Year). The study lists 3 primary outcomes in all. 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 11 Sep 2018.
