The 1 Year Follow-up Objective Oral Appliance Compliance

This study has been completed.

First received: January 31, 2012
Last updated: June 19, 2013
Last verified: June 2013

The investigators will perform a 1-year clinical trial measuring objective compliance during mandibular advancement device (MAD) treatment.

The investigators will enroll 50 patients that received treatment with a titratable, duobloc MAD (RespiDent Butterfly®, RespiDent, Nijlen, Belgium) and participated in the original study "Objective versus subjective compliance with oral appliance therapy for obstructive sleep apnea hypopnea syndrome", registered at Clinical (NCT01284881).

Active microsensors (TheraMon®,Handelsagentur Gschladt, Hargelsberg, Austria) are provided by the Handelsagentur Gschladt without any costs. The sampling interval of the recording will be done at a rate of 1 measurement per 15 minutes (every 900 seconds). Using this sample interval, the capacity of the active microsensor allows for data acquisition during a 100 day period.

A follow-up appointment is scheduled +/- 265 days after the start of the original study. A second follow-up visit is scheduled again 1 year after the start of the original study.

The objective measurement of MAD wear time (total hours of wear time and the mean hours of wear per night over the respective period) will be based on the assumption that the MAD has been worn when the chip records a temperature intraorally.

Further study details as provided by Ethisch Comité UZ Antwerpen, University Hospital, Antwerp:

Primary Outcome Measures:
  • Safety and feasibility of measuring objective mean wearing time [ Time Frame: 1 year ]
    To assess the safety and feasibility of measuring objective mean wearing time as a measure of objective oral appliance wear. The objective mean wearing time will be assessed using a microsensor thermometer. Regular follow-up visits will be performed, and patients will be questioned regarding side-effects of the microsensor.

Secondary Outcome Measures:
  • therapeutic index [ Time Frame: 1 year ]
    to calculate the therapeutic index based on objective compliance and decrease in apnea-hypopnea index / disease severity

Enrollment: 51
Study Completion Date: July 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
