Abstract

INTRODUCTION: Obstructive sleep apnea (OSA) is characterized as a chronic, progressive, disabling condition with high cardiovascular morbidity and mortality, and with repetitive episodes of upper airway (UA) obstruction. Its impact generates need for treatment. Among the treatments available and with demonstrated effectiveness, there is the option of using the oral appliances. In this study, we evaluated the effectiveness of a type of monoblock oral appliance (OA), as well as its complications and long-term complications in teaching hospital. METHODS: 20 patients participated in this study. We included patients with polysomnographic diagnosis of OSA prior mild or moderate (5> AHI <30), aged up to 60 years and not obese. The exclusion criteria were patients using psychotropic drugs, not oral condition to support the AIO and BMI and age above proposed. After 60 days of use of OA underwent a polysomnography (PSG) exam and follow-up by clinical record EDOF/HC and questionnaire RDC/TMD at baseline, 60 and 180 days. RESULTS: 11 male and nine female, mean age 51 years, and mean BMI was 27.76. The apnea-hypopnea index (AHI) showed a decrease of 19.23 to 7.51 events/hour of sleep (p = 0.001). Axis I and II of the RDC / TMD was not significantly changed in the three moments, but the axis II showed that patients in this sample have a higher degree of physical symptoms and depression than the standard. CONCLUSIONS: Oral appliance therapy for obstructive sleep apnea over the period reduced significantly the AHI and was totally or partially effective in treating 80% of patients. Complications were not homogeneous and were transient. (AU)
