Use of Intraoral Appliance in Light-to-Moderate Obstructive Sleep Apnea - Case Series Report
Obstructive sleep apnea is a prevalent disease associated with cognitive damage and increased risk to cardiovascular disease. The use of intraoral aplliances is a treatment option for patients with light-to-moderate obstructive sleep apnea.
To evaluate the effectiveness of the use of the intraoral appliances in the treatment of patients with obstructive sleep apnea.
Case series report.
All patients were evaluated by a sleep medicine doctor and submitted to a sleep evaluation with full night polysonography. Patients with light to moderate obstructive sleep apnea (AHI between 5 to 29.9 events per sleep hour), without indication of surgery, were reffered to a dental assessment for the uso of a mandibular advanced intraoral aplliance. All intraoral aplliances were made by Odonto Knoll (R). After 30 to 60 days of intraoral aplliance use, patients were submitted to another polysonography using the intraoral device. Results of polisonographies were compared.
100 Patients were assessed. 8 patients did not made de device.
N = 92. Avarege age:52 YEARS.
56% were men.
Total sleep time (mean, SD): 374.4 (190-475) Minutes;
Number of respiratory events(mean, SDE): 78 (34-162) events;
AHI (mean, SD): 12.3 (4.3 - 23.9) events/h;
Nadir varied between 61-93%.
Avarege mandibular advance was 3.3 mm (varing from 2.5 to 4.5 mm);
The use of intraoral aplliance reduced significantly the number of respiratory events and AHI, but there was no modification of total sleep time, as follow:
Total sleep time (mean, SD): 374.8 (288-453) minutes, (P> 0.05);
Number of respiratory events (mean, SD): 53 (3-165) events, (P <0.05);
AHI (mean, SD): 7.16 (0.5-22.1) events/h, (P <0.05);
Nadir varied between 74-91%.
Intraoral appliance significantly reduced the number of respiratory events and, therefore, AHI in these patients with light-to-moderate obstructive sleep apnea. These findings show the importance of intraoral appliance in the roll of obstructive sleep apnea treatment and the importance of a multidiciplinary evaluation.
