Intended Use

The Oral Device-OA is intended to reduce night-time snoring and / or mild to moderate obstructive sleep apnea (OSA) for adults 18 and older. The Oral Device-S is intended to reduce night time snoring for adults 18 and older.

Device Story

Oral Device-OA and Oral Device-S are mandibular repositioning devices (MRDs) designed to reduce snoring and/or mild-to-moderate OSA. Devices consist of pre-formed upper and lower trays; user-fitted via impression material to teeth. Oral Device-OA is fitted by a dentist; Oral Device-S is fitted by the user at home. Mechanism involves screw-based adjustment to advance the mandible, holding the lower jaw forward to maintain airway patency. Used in home (both) and clinical (OA only) settings. Output is physical repositioning of the mandible; healthcare providers use the device to manage airway obstruction during sleep. Benefits include reduced snoring and improved sleep apnea symptoms.

Clinical Evidence

Bench testing only. Testing included functional durability (180-day equivalent), flexural strength, fracture toughness, water absorption/solubility, mechanical/tensile testing, and drop testing. Biocompatibility testing (cytotoxicity, sensitization, irritation) performed per ISO 10993-1 and FDA guidance for intraoral devices.

Technological Characteristics

Mandibular repositioning device; pre-formed trays; screw-based advancement mechanism; allows lateral/vertical movement. Materials biocompatibility per ISO 10993-1. No energy source; mechanical operation. Single-patient, multi-use.

Indications for Use

Indicated for adults 18+ to reduce night-time snoring (Oral Device-S) or snoring and mild-to-moderate obstructive sleep apnea (Oral Device-OA). Contraindicated for central sleep apnea, severe respiratory disorders (asthma/emphysema), patients under 18, jaw joint disorders, severe jaw pain, loose teeth, periodontal disease, full dentures, fixed braces/retainers, or dental implants <1 year old.

Regulatory Classification

Identification

Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea are devices that are worn during sleep to reduce the incidence of snoring and to treat obstructive sleep apnea. The devices are designed to increase the patency of the airway and to decrease air turbulence and airway obstruction. The classification includes palatal lifting devices, tongue retaining devices, and mandibular repositioning devices.

Special Controls

*Classification.* Class II (special controls). The special control for these devices is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea; Guidance for Industry and FDA.”
