## Indications for Use

To be used for the treatment of simple snoring in both dentate and edentulous patients. Can be used also for the treatment of snoring in patients with periodontically comprised dentitions and likewise patients presenting with Tempero-mandibular Dysfunction (TMD). Cephalometric and videoendoscopy studies have established that tongue protrusion creates a greater, increase in oropharyngeal, velopharyngeal and hypopharyngeal cross-sectional areas of the upper airway, hence improving airway patency and function.

## Device Story

Tongue Stabilizing Device; oral appliance designed to treat simple snoring. Principle of operation: tongue protrusion to increase cross-sectional area of oropharyngeal, velopharyngeal, and hypopharyngeal upper airway regions; improves airway patency. Used by patients to manage snoring. Clinical benefit: reduction of snoring via mechanical airway stabilization.

## Clinical Evidence

No clinical data provided. Efficacy supported by cephalometric and videoendoscopy studies cited in the indications for use regarding tongue protrusion and airway cross-sectional area.

## Technological Characteristics

Mechanical oral appliance. No electronic, software, or energy-based components. Materials and dimensions not specified in provided text.

## Regulatory 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.”
