TMD Appliance IFU

Indications for use 

Dandy TMJ Appliances are intended to reduce pain and discomfort in the TMJ and in some cases help re-train muscles to avoid these movements. The devices are worn while sleeping to support patients’ TMJ  in the position prescribed by the dentists. The appliances are removable by the patient. 

Appliance Fit & Adjustments 

The dental staff or dentist should remove the appliance from packaging and rinse under water. Then place the device in the patient’s mouth, checking for proper fit and function of the appliance. The appliance adjustments should always be performed by the prescribing dentist. Any adjustments in the fit of the device should easily be made chairside to ensure that their patient is pleased with the fit and function of their new appliance.

Operating Instructions 


Brush with a toothbrush before each use. 


Dry and store in the provided case when not in use. 


All adjustments should be done by the prescribing dentist or physician. 


To properly remove the appliance, using both index fingers, pull down in the front area of the  upper appliance. 

For Dawson B-splint, do this for the upper first; second, for the lower, pull up in the front area.

To avoid breakage, do not pull down the back of the appliance. 


Expect a 2-3 year product life with the appliance. 

Appliance replacement signs are; cracks in the acrylic and failure of the device to maintain retention in the patient’s mouth. 


For the select subset of patients that have surgery to treat TMD or any TMJ issues, any further treatment with TMJ appliances / splints should be prescribed by the surgeon.
