DSP provides treatment of the deadly disease of obstructive sleep apnea by providing oral appliance therapy to individuals that cannot tolerate continuous positive airway pressure or CPAP. Oral appliance therapy refers to the use of a dental appliance, similar to an orthodontic retainer or an athletic mouth guard, which is worn in the mouth during sleep to prevent obstruction of the airway.Oral appliance therapy mechanically positions the lower jaw and tongue forward preventing the collapse of the airway and in turn reducing or eliminating your sleep apnea.
