OPR · VESTIBULAR SHIELD
Silicone Vestibular Shield
A removable oral muscle training device worn between the lips or cheeks and the teeth. Closed-lip wear and gentle traction exercises assist lip muscle function and management of selected oral habits.

Design & structure
An arched shield and an anterior traction feature form the device. Flexible silicone supports wear and training; the anterior traction feature is used for lip-resistance exercises under professional guidance.
Clinical use & follow-up
Habitual open-mouth posture or mouth breathing requires prior assessment of nasal patency and airway concerns. Do not force closed-lip wear. If pain, mucosal injury or breathing discomfort occurs, remove the device immediately and contact the clinician.
Sizes & selection
| Model / size | Selection basis |
|---|---|
| Clinician-selected size | Dentition stage, vestibular dimensions and fit |
The clinician selects the model using the stage of dental development, the dimensions of the oral vestibule and the fit of the device.
Reference ages are selection guides, not a treatment prescription. Final selection, wear and review follow clinical assessment and the applicable product instructions.
