Abstract

Purpose The aim was to analyze whether or not weight gain influences the treatment outcome of patients with obstructive sleep apnea (OSA) treated with mandibular advancement devices (MAD).
Methods As a part of a follow-up study among OSA patients treated with MAD in primary oral health care, a group of 28 patients reporting worsening of daytime or nighttime symptoms of OSA was given closer examination. Altogether, 21 subjects had a complete set of recordings and were enrolled into the study.
Results Only three subjects had lost weight during the study period. The mean weight gain of 3.6 kg ± 7.1 kg was significant (p = 0.035). According to linear regression, weight gain was independently significantly associated with lower mean peripheral oxygen saturation 92.4 (SD 1.8 (% per hour) (p = 0.019)) and lowest oxygen saturation 80.1 (SD 7.2 (%) (p = 0.024)) scores.
Conclusions Weight gain is detrimentally associated with MAD treatment in patients with OSA. These findings suggest that regular follow-up by an experienced dentist is advisable to assess for possible worsening of OSA. Patient support to encourage weight control may be an important adjunct to MAD treatment for OSA.
