Abstract

Objective To identify potential risk factors of response to oral appliance in patients with obstructive sleep apnea (OSA). Methods Fifteen OSA patients were enrolled. Clinical characteristics, cephalometric measurements, and the results of home sleep testing were retrospectively obtained at baseline, and a sleep test was done again at the end of treatment. Results Twelve subjects were responders and three were non-responders. The diastolic blood pressure, minimum pulse rate, SNA (Angle between sella-nasion and nasion-A point), ANB (Anteroposterior maxilla/mandible discrepancy), and facial convexity of non-responders was higher than those of responders. Unlike AHI, non-responders showed a lower lowest oxygen saturation (%) than responders. Discussion Elevated diastolic pressure and minimal pulse rate, higher skeletal convexity and lowered lowest oxygen saturation might be risk factors to oral appliance efficacy in the OSA patients. More research in a large sample is needed to verify the results of the current study.
