How the TMD works

The Myosa® TMD appliance is specifically designed for the diagnosis and treatment of TMJ disorder. The appliance, which should be fitted and customised by your doctor to the correct therapeutic bite, has a comfortable low profile allowing for daytime use and unimpeded speech. While the flexible Myosa® TMJ is ideally suited to night time use, the Myosa® TMD can be used while sleeping provided the fit is secure. Use for short periods during the day initially, then once comfortable use all day removing only for eating or cleaning.

Instructions for use:

Prior to using the Myosa® TMD see a medical or dental practitioner for evaluation of your TMJ disorder to determine the potential benefit of the appliance in conjunction with other treatments. The Myosa® TMD serves as both diagnostic tool and initial treatment modality and can determine if your symptoms are directly related to causes of TMJ disorder. Use for short periods during the day initially, then once comfortable use all day removing only for eating or cleaning. The Myosa® TMD appliance must be fitted by your doctor. After fitting ensure it fits tightly and can be easily removed and replaced into the correct position.

TMD instructions

Step 1 – Hold the Myosa® facing right way up.
Step 2 – Place the Myosa® into your mouth.
Step 3 – Close down on the Myosa® and allow it to guide your jaw forward.
Step 4 – Make an effort to keep the lips together and breathe through the nose.

Initially when removed the teeth may feel they do not meet. This is common and indicates the Myosa® TMD has identified a bite problem.

Cleaning the TMD appliance
The TMD appliance should be cleaned under warm running water every time the patient removes it from their mouth. Use Myoclean™ tablets to correctly clean twice a week. Myoclean™ is the recommended cleaning agent for MRC's appliances.
