The primary oral appliance (OA) used in obstructive sleep apnea (OSA) treatment is the mandibular advancement device (MAD). MADs may be either an over-the-counter stock device or customized for individual patients. MADs come in various designs and materials, but most comprise upper and lower splints mounted over the dentition as either a 1-piece monoblock or a 2-piece biblock Connectors or blocks relate the upper and lower splints in a biblock to protrude the mandible in a forward position during sleep.~Although the efficacy of oral appliances has been proved, the relationship to the nature of airway enlargement in patients with OSA has not yet been clearly demonstrated.~The aim of this study is therefore to evaluate the efficacy mandibular repositioning appliance reduces sleep apneas symptoms with mild to moderate obstructive sleep apnea . Secondary outcomes include the dental side effects of such appliance. At baseline and after 4 month's treatment, This study will be conducted to estimate frequency of OSA on population sample from Erbil study, in addition trying to evaluate the efficiency of MAD on some patients who are diagnosed with OSA.
The purpose of this study is to evaluate efficacy of mandibular advancement device (MAD). on treating obstructive sleep apneas, symptoms, Apnea/Hypopnea Index (QHI) and the Respiratory Arousal Index (AHI/REI) and peripheral capillary oxygen saturation (SpO2) Range, PULSE in patients with mild to moderate obstructive sleep apnea/hypopnea syndrome, and evaluating potential dental side effects
