Background: Many patients with obstructive sleep apnea (OSA) are mouth-breathers. Mouth-
breathing not only narrows the upper airway, consequently worsening the severity of OSA …

Rationale: Mouth breathing increases upper airway collapsibility, leading to decreased
efficacy of obstructive sleep apnea (OSA) treatments. We hypothesized that the use of …

Study objectives: Mouth leak compromises nasal continuous positive airway pressure
(CPAP) therapy. We hypothesized that patients who breathe mainly through their mouths …

Purpose This study aimed to design a device to monitor mouth puffing phenomena of
patients with obstructive sleep apnea when mouth-taped and to employ video recording and …

Purpose To compare the efficacy of tongue-retaining device (TRD) versus continuous
positive airway pressure (CPAP) for treatment of obstructive sleep apnea (OSA). Study …

Background and purpose: Mouth leak occasionally complicates continuous positive airway
pressure (CPAP) therapy, which leads to discomfort. While a chinstrap prevents the mouth …

This study aimed to explore the effect of mandibular advancement splints (MAS) on upper
airway anatomy during wakefulness in obstructive sleep apnoea (OSA). Patients …

Background and objective During continuous positive airway pressure (CPAP) treatment,
some patients with obstructive sleep apnoea syndrome (OSAS) require an oronasal mask …

Objective: To compare three different oral appliances: a mandibular advancement device
(Snoreguard), a tongue retaining device, and a soft palate lift, for treatment of severe …

Oral appliances (OA s) have demonstrated efficacy in treating obstructive sleep apnea
(OSA), but many different OA devices are available. The Japanese Academy of Dental Sleep …
