“…In one of the study 1 done in past on 6 edentulous patients it was observed that retropharyngeal space was reduced from 15mm to 6mm, leading to increased apnea hypopnea events. Later on same results were obtained in another study 3 in which the authors hypothesized that edentulism might act in creating the apnoea condition by modifying anatomy and thereby affecting the functions of the pharyngeal airway and of tongue and may be by favouring inflammatory edema. They concluded that risks of removing denture in edentulous patients should be weighed against risk of upper airway collapse.…”

“…3 Obstructive sleep apnea syndrome (OSAS) is a disorder characterised by repeated obstruction of the upper airway, with consequent episodes of apnea and hypoapnea during sleep, snoring, and day time sleepiness. 4,5 Increased pharyngeal collapsibility is reported to be a common cause of obstructive sleep apnea.…”

“…Many authors suggest that denture has a protective role on OSAS onset [24][25][26][27]. Its function is to improve a vertical dimension of occlusion (VDO) increase, a correct tongue position, an upper airway collapse reduction and a mandibular advancement.…”

Abstract:Purpose: Obstructive sleep apnea (OSA) is a common disease that is estimated to affect 2% of middle-aged women and 4% of middle-aged men. Reported risk factors include obesity, increased neck circumference, male sex and anatomical abnormalities of the face. Although edentulism is reported to change the anatomy and also impair the function of the upper airway, it has not been typically recognized as a risk factor for sleep-related breathing disorders. Methods:The subject of this report is a 55 years old man with a body mass index (BMI) of 33 kg/m 2 . Cephalometric assessments of head radiographs taken in the lateral plane with and without dentures were performed; mandible planehyoid (MP-H) distance and the posterior airway space (PAS) were measured. Oxygen saturation (SaO 2 ) and apnea/hypopnea index (AHI) were evaluated.Results: A comparison of the polysomnographies taken with and without wearing the dentures during the night showed that AHI was reduced (from 20.0/h to 5.7/h) and mean SaO 2 increased (from 94.0% to 96.0%). Cephalometric analysis showed that the removal of dentures led to a striking increase in the anteroposterior oropharyngeal wall distance from 5 mm to 10 mm, while the mandible plane-hyoid distance does not change. Conclusions:These findings were consistent with the hypothesis that edentulism not always worse OSA by an oropharyngeal collapse. Given the common occurrence of both conditions among the elderly, such as the reduction of obstructive sleep apneas with or without dentures, the observed relationship requires further investigations on the mechanisms through which the loss of teeth could help upper airway collapse during the night. In the present paper a case of reduction of OSA without dentures during sleep is shown.

“…8 Erovigni et al (2005) demonstrated that wearing denture induces modifications in the position of the tongue, mandible and pharyngeal airway space which can favor the reduction of apnea episodes. 6 Bucca et al (2006) concluded that edentulism might worsen obstructive sleep apnea, particularly in subjects with no respiratory disturbances sleeping with dentures. Edentulism might act by modifying anatomy and function of the pharyngeal airway and tongue and favoring inflammatory edema.…”

“…They suggested that the advantage of removing dentures during sleep should be weighed against the risk of favoring upper airway collapse. 4 Arisaka et al (2009) concluded that wearing complete dentures during sleep improves the AHI of most edentulous OSA patients. 10 Tsuda et al (2010) found the prevalence of suspected SDB in edentulous subjects was higher than in the general population.…”
