With so many different oral appliances available, a selection of a specific appliance may appear somewhat overwhelming. Nearly all appliances fall into one of two categories. The diverse variety is simply a variation of a few major themes. Oral appliances can be classified by either mode of action or design variation: Tongue Retaining Appliances. Tongue retaining appliances function by holding the tongue in a forward position by means of a suction bulb. When the tongue is in a forward position, it serves to keep the back of the tongue from collapsing during sleep and obstructing the airway in the throat. Mandibular Repositioning Appliances. These help to reposition and maintain the lower jaw (mandible) in a protruded position during sleep. This serves to open the airway by indirectly pulling the tongue forward, stimulating activity of the muscles in the tongue and making it more rigid. It also holds the lower jaw and other structures in a stable position to prevent opening of the mouth. Dentists with training in oral appliance therapy are familiar with the various designs of appliances, and they can determine which one is best suited for your specific needs. The dentist will work with your physician as part of the medical team in your diagnosis, treatment, and ongoing care. Determination of effective treatment can only be made by joint consultation of your dentist and physician. The initial evaluation phase of oral appliance therapy can take anywhere from several weeks to several months to complete. This includes examination, evaluation to determine the most appropriate oral appliance, fitting, maximizing adaptation of the appliance, and its function. |
