Comparison of Standing Versus Supine 3D Cone Beam Computed Tomography in Patient With Obstructive Sleep Apnea (OSA)
April 30, 2021 updated by: Dr. Maryam Bakhtiyari, Manhattan Beach Orthodontics
Reduction of Volumetric and AP Measurements of the Airway in Pseudo-sleep Supine Position vs Standard 3D Cone Beam Computed Tomography on Patients With Sleep Apnea
The anatomical changes of the upper airway in a standing vs pseudo-supine position using Carestream Orthodontic Imaging (Volumetric) and Carestream Orthodontic Imaging module (AP measurements) of the patient's airway respectively, have been taken and the obtained results compared.
In order to simulate the supine position, patients are placed in a supine position (180 degrees) in a dental exam chair, and asked to relax their lower jaw, allowing it to drop back, simulating their jaw falling back while sleeping.
That bite is then captured with a Correct Plus™ Impression Material Superfast.
Once the bite material hardens, it locks the bite in place.
The patient then stands upright, and CBCT is taken standing while the jaw placement is still pseudo sleep-supine, supported by the bite material.

Study Population
The five or six individual patients enrolled are the members of the sole group, the study population.
These individuals all have been diagnosed with obstructive sleep apnea and have take a Cone-beam CT scan with and without the new bite technique.

Measure Description |
Time Frame |
---|---|---|
3D volumetric airway measurement
Time Frame: through study completion, an average of 1 year
|
Investigators will measure and compare the 3D volumetric airway of the x-ray both with and without the pseudo-supine technique.
This will be done on the computer using Carestream Orthodontic Imaging.
|
through study completion, an average of 1 year
|
2D Anterior-Posterior airway Measurement
Time Frame: through study completion, an average of 1 year
|
Investigators will measure and compare the 2D anterior-posterior airway of the x-ray both with and without the pseudo-supine technique.
This will be done on the computer using the Carestream Orthodontic Imaging module.
