OSA Appliance + patient opens mouth

PURPOSE: To compare the efficacy of twin-block (i.e., allows mouth opening) and fixed (i.e., maintains mouth closure) mandibular advancement splints (MASs) for the treatment of obstructive sleep apnea-hypopnea syndrome (OSA). MATERIALS AND METHODS: From 2011 to 2013, 23 patients with OSA in the twin-block group, and from 2013 to 2015, 29 patients in the fixed MAS group were included. All patients underwent polysomnography before and after 3 months of treatment. The two sets of polysomnographic and cephalometric variables were compared...

BACKGROUND: Infants with Robin sequence (RS) suffer from upper airway obstruction (UAO) and feeding problems. We developed an oral appliance with a velar extension in combination with functional treatment and appropriate feeding techniques, which was proven effective in isolated RS. As the above problems are particularly challenging in syndromic RS, we set out to evaluate our treatment concept also in these patients. METHODS: We searched our electronic departmental database to identify all children admitted to our department between 01/01/2003 and 31/12/2009 because of syndromic RS...

BACKGROUND: Oral appliances (OAs) hold the lower jaw forward to reduce obstructive sleep apneas. Some OA designs allow mouth opening, which influences the forward positioning of the lower jaw. The aim of this pilot study was to compare the efficacy of an adjustable, custom-made OA (Narval®) in its original design, which allowed mouth opening, with the same OA with elastic bands that restricted mouth opening. METHODS: Consecutive patients with an apnea-hypopnea index (AHI) of ≥15 were randomized to start with an OA either with or without elastic bands in a single-blinded, crossover, pilot study...

Oral appliances (OAs) have demonstrated efficacy in treating obstructive sleep apnea (OSA), but many different OA devices are available. The Japanese Academy of Dental Sleep Medicine supported the use of OAs that advanced the mandible forward and limited mouth opening and suggested an evaluation of their effects in comparison with untreated or CPAP. A systematic search was undertaken in 16 April 2012. The outcome measures of interest were as follows: Apnea Hypopnea Index (AHI), lowest SpO2 , arousal index, Epworth Sleepiness Scale (ESS), the SF-36 Health Survey...

AIMS: To evaluate the prevalence of pain associated with temporomandibular disorders (TMD) in obstructive sleep apnea syndrome (OSAS) patients referred for oral appliance therapy. METHODS: Eighty-seven patients (46 men and 41 women), between 18 and 65 years of age, with an apnea-hypopnea index (AHI) of > 5 and < 30 (events by sleep hour), and body mass index (BMI) of =or< 30 Kg/m(2) were evaluated according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) to determine the presence of signs and symptoms of TMD...

INTRODUCTION: Mandibular advancement (MA) has emerged over the last decade as an alternative solution to nasal continuous airway pressure (nCPAP) for the treatment of obstructive sleep apnea syndrome (OSAS). OBSERVATION: We report the case of a patient with history of chronic atrial fibrillation and moderate supine-dependent OSAS in whom central sleep apneas developed during treatment by a bi-bloc MA device. Central apneas increased with the level of MA and preferentially occurred in the supine position...

The therapeutic effect of a functional magnetic system on obstructive sleep apnea and the system's operating mechanism have not been examined. Two hypotheses are postulated: a functional magnetic system increases the size of the oral cavity airway passage, or it increases the pharyngeal space. Twenty-eight patients with mild-to-moderate obstructive sleep apnea were examined; 10 patients (9 men and 1 woman; aged, 50.5 +/- 2.6 years) met the study criteria. After baseline nocturnal polysomnography and daytime tiredness self-evaluation, a functional magnetic system was inserted...
