The Diamond Digital Sleep Orthotic (DDSO) is a removable intraoral device intended to reduce or alleviate snoring and mild to moderate obstructive sleep apnea (OSA) in adults. The device functions as a mandibular repositioner, maintaining the lower jaw in a forward, (protrusive) position during sleep. This mechanical protrusion acts to increase the patient’s pharyngeal space and decrease air turbulence, therefore improving their ability to exchange air during sleep.
