Indications:

• Obstructive Sleep Apnea (OSA) – mild to moderate cases.

• Primary snoring.

• Upper airway resistance syndrome.

• Patients intolerant or non-compliant with CPAP.

• As adjunct therapy in orthodontic/orthognathic patients with airway concerns.

Contraindications:

• Severe OSA needing CPAP or surgical management.

• Patients with extensive edentulism (poor retention).

• Severe TMJ dysfunction or limited mandibular protrusion.

• Poor periodontal support.

Corrects:

• Reduces pharyngeal airway collapse during sleep.

• Maintains mandible in an advanced position → increases retroglossal airway space.

• Has nasal dilator components that stent the nasal valve → reduces nasal resistance.

• Improves airflow both nasally and orally.

Design:

• Intraoral mandibular advancement device with dual action:

  • Oral component: holds mandible in protrusion (advances tongue base).

  • Nasal dilator tabs/flares: fit inside nasal vestibule to enlarge nasal valve area.

• Custom fabricated, usually with upper and lower splints linked to maintain protrusion.

• Adjustable for mandibular advancement (stepwise titration).

Philosophy:

• Combined oral and nasal airway management in one device.

• Unlike conventional mandibular advancement devices (MADs), it addresses both retroglossal obstruction and nasal valve collapse.

• Improves oxygen saturation, reduces snoring, and decreases apnea-hypopnea index (AHI).

Modifications:

• Can be fabricated with variable degrees of mandibular advancement (titration).

• With or without nasal dilator flares, depending on patient need.

• Can be integrated with orthodontic/surgical planning for airway patients.

Advantages:

·         Designed for sleep-disordered breathing → effective for mild to moderate obstructive sleep apnea (OSA) and snoring.

·         Dual action design → advances the mandible and gently opens nasal airway (via nasal dilator mechanism).

·         Improves oxygenation and sleep quality → by maintaining airway patency throughout the night.

·         Minimally invasive alternative → to CPAP in selected patients with higher comfort and compliance.

·         Custom-fit fabrication → ensures retention, comfort, and ease of nightly wear.

·         Encourages nasal breathing → reduces mouth breathing and associated complications.

·         Lightweight, low-profile appliance → increases patient acceptance compared to bulkier devices.

·         Durable materials from Maxdent → precision acrylic and metal components for longevity.

·         Adjustable design → allows titration of mandibular advancement for optimal effect.

Lightweight and easy to carry.
