    PURPOSE: There is an increasing tendency to use oral appliance (OA) as an alternative treatment for sleep apnea. Here we report the long-term adherence and clinical effects of OA therapy. METHODS: All sleep apnea patients treated at the Department of Dentistry between the years 2006 and 2013 (n=1208) were reviewed. A questionnaire about OA adherence, asthma symptoms (Asthma Control Test™, ACT), and general health was sent to all patients who continued OA therapy after the 1-month follow-up visit (n=811). OA was adjusted to obtain at least 70 % of the maximal protrusion of the mandible. RESULTS: The response rate was 37.4 % (99 women, 204 men). The mean±SD age and BMI were 58.7±10.3 years and 27.3±4.0 kg/m(2), respectively. During the mean follow-up period of 3.3 years, there was no significant variation in BMI. Forty-one patients abandoned OA therapy yielding an adherence rate of 86 %. Ninety-seven percent of patients used OA ≥4 h/day, and the mean daily use was 7.2±1.1 h. The ACT score improved with OA use from 16.0±5.9 to 20.1±3.8 (p=0.004), indicating better asthma control. The apnea and hypopnea index decreased significantly from 27±19 at baseline to 10±10 with OA therapy (p=0.001). CONCLUSIONS: After a 1-month trial period, the long-term adherence to oral appliance was good. OA therapy decreased apneas and hypopneas significantly, and its long-term use was associated with an improvement in respiratory and asthma symptoms.
