Abstract
Background Assessment of the overall therapeutic effectiveness of oral appliance therapy can only be realized through objectively measured compliance. The objective is to assess objectively measured compliance during oral appliance therapy at 1-year follow-up, and to compare these objective compliance data with self-reported use. Methods 51 eligible patients were enrolled in this 1-year prospective clinical study (61% male; age: 49 ± 10 years; AHI: 18.0 ± 11.9/hour sleep; BMI: 26.6 ± 4.1 kg/m2). Objective compliance during oral appliance therapy at 1-year follow-up was assessed using a microsensor thermometer (TheraMon®, Handelsagentur Gschladt, Austria). Subjective compliance was assessed using self-report. Patients with a mean objectively measured use of ≥ 4 hours/night on 70% of nights monitored were considered regular users. The mean disease alleviation was calculated as a measure of overall therapeutic effectiveness. Results High agreement between objective and subjective compliance data at 1-year follow-up was reported (ICC = 0.8; 95% CI 0.5; 0.9), showing a mean subjective overestimation of 30 minutes (p = 0.02; 95% CI -3.1; 1.9). The discontinuation rate at 1-year follow-up was 9.8%. The objective mean use rate was 6.4 ± 1.7 hours per night at 1-year follow-up in continuing users, with a regular use rate of 83%. The mean disease alleviation was 54.8%. Conclusions The present study is the first report on the 1-year results of objectively measured compliance during oral appliance therapy. In addition, a high agreement between objective and subjective compliance data was reported, with a mean subjective overestimation of 30 minutes.
