Intended 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.

Indications for Use

Indicated for treatment of simple snoring in dentate and edentulous patients, including those with periodontically compromised dentitions or Temporomandibular Dysfunction (TMD).

Regulatory Classification

Identification
