Oral Appliance Therapy

What is Oral Appliance Therapy?


Oral appliance therapy (OA) is recommended for patients with obstructive sleep apnea (OSA) who can’t tolerate continuous positive airway pressure (CPAP) therapy or prefer alternate therapy.  Also known as a mandibular repositioning device, an OA is a small, plastic device that fits in the mouth similar to an orthodontic retainer or a sports mouthguard.  The OA holds the lower jaw forward to help keep the airway open and prevents apneas (pauses in breathing) while sleeping. They’ve gained in popularity because they’re small, simple to use and ideal for travel.


Oral Appliances

A variety of oral appliances are available for the treatment of OSA. These devices may be used alone or in conjunction with other means of managing OSA, such as weight management or CPAP.

Custom-made OAs are proven to be more effective than over-the-counter or online-purchased OAs, which are not recommended. Several factors need to be taken into consideration when making an OA, such as teeth grinding or TMJ. A dentist that makes oral appliances can best determine what type of OA is best for you and what level of advancement is needed. Additionally, the dentist may also work with the patient’s health care provider or sleep specialist throughout the OA therapy process.
