SomnoDent Avant / Flex

SomnoDent is the flagship MAD brand from SomnoMed (Australia). The Avant model uses CAD/CAM 3D-printed resin with anterior interchangeable straps, while the Flex model uses traditional clear acrylic with lateral dorsal wing screws.

Avant: • 3D-Printed Resin Trays — Ultra-thin (~1.0mm) CAD/CAM design • Anterior Interchangeable Straps — 1mm incremental advancement per strap • Passive Mouth-Closing Design — Encourages nasal breathing Flex: • Clear Acrylic Trays — Traditional heat-cured PMMA • Dorsal Wing Screws — Lateral adjustment, 0.4mm per turn, 6mm total

Avant: Interchangeable anterior straps pull the mandible forward in 1mm increments. The thin profile maximizes comfort. Flex: Dorsal wing screws on the lateral aspects push the mandible forward. Both models feature a passive mouth-closing design that promotes nasal breathing — a key advantage for OSA patients.
