A summary of the article is shown below:
Obstructive sleep apnea (OSA) is defined as episodes of upper airway obstruction occurring during sleep. Conservative treatment of OSA consists of continuous positive airway pressure (CPAP). An alternative treatment in mild-to-moderate OSA could be the use of intraoral mandibular advancement devices (MAD). The aim of this study was to evaluate therapeutic efficacy of MAD in OSA patients intolerant to CPAP. The study group included 8 patients, who fulfilled specific inclusion criteria during a dental examination, out of the 30 CPAP intolerant patients who were referred for the possible use of MAD. The selected patients used MAD for 30 days and then switched to CPAP for 10 days to compare the effectiveness of both treatment methods. They had 3 polysomnographic (PSG) examination: baseline before treatment, and at the end of MAD and CPAP. We found that either treatment method resulted in comparable symptomatic improvements in OSA patients. In detail, the apnea-hypopnea index decreased, along with the overall number of obstructive, central, and mixed apneic episodes during sleep time. The mean arterial oxygen saturation (SaO2) improved and the minimum SaO2 level noted during night time got enhanced. Differences in the sleep apnea indices after MAD and CPAP treatments were insignificant, but there was a consistent impression that CPAP was superior to MAD as it tended to improve symptoms to a somehow greater extent. We conclude that MAD is a sufficiently effective treatment alternative for OSA patients who are intolerant to CPAP or in whom CPAP therapy fails.
