Mandibular Advancement Splints.

Although mandibular advancement splints (MAS) are not as efficacious as continuous positive airway pressure (CPAP) in reducing obstructive respiratory events, patient adherence and preference are greater than CPAP. Additionally, the effectiveness of both treatments on general health outcomes, cognitive function, and quality of life appears to be equivalent. The main barrier for the implementation of MAS treatment in clinical practice is the interindividual variability in response to MAS treatment. Several prediction tools have been proposed to enhance patient selection for MAS treatment. Phenotyping obstructive sleep apnea patients may reveal patient characteristics that enable the prediction of response to MAS treatment.
