Product
The core device is a personalized mandibular-advancement appliance worn in the mouth during sleep. Suenia describes a professional pathway for determining the therapeutic jaw position, fitting the appliance and monitoring treatment with sleep and dental specialists.
Individual jaw positioning
The fitting approach determines a therapeutic lower-jaw position for each patient. Advancing the jaw aims to create more space in the upper airway and reduce the collapse that interrupts breathing during sleep.
Specialist-led assessment
The clinical pathway combines assessment by sleep specialists, ear, nose and throat physicians, and dentists. Dental health and the severity of sleep apnoea help determine whether an oral appliance is appropriate.
Adjustment and follow-up
Dentists adapt the appliance to the patient and review comfort and fit over time. Follow-up evaluates symptoms and treatment control, with further adjustments or sleep testing considered when clinically needed.
Market Overview
Obstructive sleep apnoea is treated with CPAP, oral appliances and, in selected cases, surgery. Mandibular advancement devices are a clinically established alternative for patients who cannot tolerate CPAP, creating a specialist market spanning sleep clinics and dental providers. Adoption depends on fit, comfort and objective treatment response.
