How do Cerezen™ inserts work?

Inner ear diagram with Cerezen™ device inserted

 

The ear canal is located very close to the temporomandibular joint (TMJ). The shape of the ear canal changes somewhat when the jaw is opened or closed through movements such as chewing, smiling, and speaking. Cerezen™ inserts use this anatomical change to provide a unique near-field treatment for TMJD.

Cerezen™ inserts can be greater than 20% larger in their dynamic geometry than the ear canal when in a jaw-closed position. It is this change in ear canal space, as well as the inserts’ proximity to the TMJ and surrounding muscle and nerve tissue, that is believed to apply subtle pressure against the walls of the ear canal. This encourages the patient to return to the “open bite” position, thus minimizing the tendency to clench the jaw and surrounding muscle.
