About this study

Official title: Therapeutic Efficiency Analyses of Mandibular Advancement Devices on Obstructive Sleep Apnea Using Polysomnography, Smartphone Sleep Applications, and Simple Pulse Oximeter

An observational clinical trial in a single centre. The objective of this study was to determine the efficacy of mandibular advancement device (MAD) therapy on snoring intensity, frequency, and oxygen desaturation periods in mild-moderate obstructive sleep apnea (OSA) patients with snoring problems. Totally, 18 mild-moderate OSA patients (8 females and 10 males) with subjective snoring complaint were selected. Each patient's diagnostic polysomnographic analysis (PSG) was accepted as initial PSG values. Each patient was subjected simple pulse oximeter (SPO) and smartphone sleep application (SSA) at 3 different nights at home. Diagnostic mean values of oxygen desaturation index (obtained by using SPO), snoring intensity score (obtained by using SSA), and snoring percentage (obtained by using SSA) were recorded. Non-titratable-customized MAD with 60-75% of maximal mandibular protrusion were fabricated. The patients were instructed to wear their MAD every night. SPO and SSA measurement were repeated at the 1st, 4th, 12th, and 24th week of the treatment process. At the 24th week of treatment, The PSG were repeated and all PSG, SPO, and SSA values were compared with initial diagnostic values.

What participants receive

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

  • Non-titratable-customized mandibular advancement deviceDevice

    The most comfortable protruded mandibular position situated between 60-75% of MMPV was determined according to patient response with 6mm of the vertical interocclusal dimension between maxillary and mandibular central incisors and registered. The upper and lower acrylic resin splints were secured to each other in the posterior region with auto polymerizing acrylic resin and NTC-MADs were obtained. The patients were instructed to wear their non-titratable-customized mandibular advancement device every night.

Study groups in NCT04427111
Study groupRoleWhat they receive
Mild-moderate OSA patients for MAD treatmentPatients are classified as mild Obstructive Sleep Apnea (OSA) if they have between 5-15 Apnea-Hypopnea Index, moderate if they have between 15-30, and severe if they have >30, as measured by Polysomnography (Epstein LJ, Kristo D, Strollo PJ, et al. 2009). The principal treatment methodology for OSA patients is positive airway pressure. In patients with mild to moderate OSA, oral appliances such as mandibular advancement devices (MAD) is alternately indicated (Ramar K, Dort LC, Katz SG, et al. 2015) The American Academy of Dental Sleep Medicine (Ramar K, Dort LC, Katz SG, et al. 2015) recommended titratable-customized MADs for patient comfort and the ability to permit modifications in the amount of mandibular protrusion for treatment efficacy. However, Aarab et al (Aarab G, Lobbezoo F, Hamburger HL, Naeije M. 2010) demonstrated similar therapeutic efficiency of non-titratable-customized MADs in the treatment of OSA

What is being measured

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

  1. Change from Baseline Apnea-Hypopnea Index (AHI) at 6 months

    AHI was defined as total number of apnea or hypopnea events which lasts for at least ten seconds per hour during full nigth polysomnography (PSG) and accepted to be the main physiological sleep parameter in the present study. The AHI values were used for the evaluation of the severity of OSA and the MAD's treatment success in OSA patients

    Measured: at baseline and in 6 months

Secondary outcomes (5)
  1. Oxygen-desaturation index (ODI)

    ODI was used to evaluate the desaturation fluctuations during full night PSG. ODI is defined as 3-4% decrease in oxygen saturation per hour.

    Measured: at baseline and in 6 months

  2. Snoring index (SI)

    SI was used to evaluate snoring events per hour during PSG

    Measured: at baseline and in 6 months

  3. Simple pulse oximeter (SPO)/ODI

    SPO/ODI was used to evaluate the desaturation fluctuations during sleep in-home environment by using simple pulse oximeter device

    Measured: at baseline and 1, 4, 12, and 24 week of MAD treatment

  4. Smartphone sleep application (SSA)/snoring intensity score (SIS)

    SSA/SIS was used to evaluate snoring intensity that was calculated by SSA during sleep in-home environment. No information exists about how to calibrate the SSA to calculate SIS

    Measured: at baseline and 1, 4, 12, and 24 week of MAD treatment

  5. SSA/snoring percentage (SP)

    SSA/SP was the ratio of total snoring time to total sleep time that was calculated by SSA during sleep in-home environment. No information exists about how to calibrate the SSA to calculate SP.

    Measured: at baseline and 1, 4, 12, and 24 week of MAD treatment
