Frequently Asked Questions:

What are the indications for using the Restful Jaw?

Any long dental procedure for supporting the mandible from the dental forces on the jaw. Other key indicators include: Symptomatic TMJ/TMD patients; asymptomatic patients with signs of TMD; movement disorders (e.g., Tardive dyskinesia, Parkinson, MS, or geriatric patients) – hyperactivity can be reduced by securing the device shoulder straps around dental chair, instead of the patient.

How does the Restful Jaw work?

The Restful Jaw’s memory foam cushion supports the patient’s mandible in the open mouth position. With the device’s support, patients do not have to tense their jaw muscles to hold their mouth open. The Restful Jaw is clinically proven to minimize jaw pain, fatigue and soreness from dental procedures.

Does the device fit all patients?

Our ongoing field studies show that the Restful Jaw fits a wide range of adult sizes and shapes.

Will the device interfere with my dental work?

No. The device supports the patient’s mandible and does not get in the way between you and the patent’s mouth.

Will the device block access to the patient’s airway?

Based on our clinical studies with sedated patients, the device does not block access to the patient’s airway.

Can the device be used in pediatric dentistry?

The current device is made to fit adult-size patients. A separate product extension is currently under design for pediatric dentistry.
