Oral appliances are easy to use and are often preferred by many to prevent snoring and treat OSA. They are often custom made for individuals (6). They help by increasing the size of the upper airway and decreasing its collapsibility. Most commonly used oral appliances are mandibular repositioning appliances (MRA) and tongue retaining devices (TRD). MRAs help by keeping the mandible or lower part of the face in more advanced position, while TRDs hold the tongue in forward position. These devices have shown to be useful in at least two-third of cases, and people often find them easy to use. Though initially, they are bit uncomfortable, soon a person gets used to them.
