Brief Summary

Mandibular Advancement Devices (MADs) are now a reliable alternative to continuous positive airway pressure (CPAP) treatments for Obstructive Sleep Apnea (OSA) . Despite good tolerance and efficacy, there are still barriers limiting the widespread use of MAD and its acceptance in OSA routine clinical practice. Various MAD designs currently exist and constantly emerge on the market without clear evidence regarding the best technical choice and the cost-effectiveness compromise. Although these MAD has been tested in term of efficacy, no study has tested the difference between MADs in term of efficacy, tolerance and patient satisfaction. The aim of this clinical trial is to compare the effectiveness of two MADs - custom-made titratable MAD (NarvalTM) and customizable titratable MAD (TALITM), over a 3-month period, in patients with obstructive sleep apnea (OSA).

Outcome Measures

Primary Outcomes (1)

  • Comparison of efficacy of two Mandibular Advancement Devices: NarvalTM and TALITM

    The difference of effectiveness between Mandibular Advancement Devices will be assessed using the difference of delta AHI, measured by Polysomnography, between the visit 2 (M3) and the Polysomnography before Mandibular Advancement Devices installation.

    at the end of the 3-month period

Secondary Outcomes (9)

  • To compare the efficacy of titration with each Mandibular Advancement Devices

    between the oral appliance delivery and the end of the titration period at 3 months

  • To compare the number of patients appropriately treated by Mandibular Advancement Devices between the two devices

    after 3 months of treatment with mandibular advancement device

  • To compare the tolerance in the 2 arms

    after 3 months of treatment

  • To compare the sleep quality

    after 3 months of treatment with mandibular advancement device

  • To compare the mandible behavior (mandibular movement (MM)) during sleep) with each Mandibular Advancement Device

    after 1 month and 3 month of treatment with each Mandibular Advancement Device

  • +4 more secondary outcomes

Study Arms (2)

Mandibular Advancement Devices Narval™

EXPERIMENTAL

The tested device Narval™ will be a custom-made adjustable bi-block mandibular advancement device, that is made with semi-rigid plastic materials (bio-compatible polymer) and customized using a high-precision computer-aided design (CAD)/computer-aided manufacturing (CAM) ) (ResMed, Narval CC™). The Mandibular Advancement Devices will be gradually adjusted to provide mandibular advancement over a 15-mm range. Each Mandibular Advancement Device will be fitted by a dental specialist with an initial advancement of about 60 % of maximal jaw protrusion. During titration, mandibular advancement will be adjusted at the discretion of the dental specialist.

Device: custom-made adjustable mandibular advancement device

Mandibular Advancement Devices TALI ™

ACTIVE COMPARATOR

The control device TALI ™ is a mandibular advancement orthesis, customized and manufactured by the "laboratoire TALI", of the bi-bloc type consisting of rigid gutters thermo-formed on the plaster dental arches and articulated by two links of variable size allowing to adjust the advance in steps of 1 millimeter. This orthesis is manufactured on molding from bio-compatible plastic materials. The different sizes of rods proposed allow mandibular advances of 4 mm to 16 mm. Two clinical studies evaluated the effectiveness of the AMC / AMO orthosis (initial version of the TALI orthesis, with non-curved links) in patients with OSA. They have already demonstrated the effectiveness of the TALI orthesis by decreasing AHI and drowsiness; most patients preferred to use the orthesis (76.4% vs. 9.1%)11.

Device: custom-made adjustable mandibular advancement device

Interventions

a custom-made mandibular repositioning device (MRD), available under medical prescription for the treatment of adult obstructive sleep apnea (OSA) and snoring. It maintains the mandible in an advanced position along the occlusal plane. This ensures patient comfort and treatment efficacy.

Also known as: mandibular advancement orthosis (MAD)
