Myosa® for TMJBDS® Stage 1 - S1

Establish a functional airway and habit correction

The Myosa®for TMJBDS®S1 is used in patients with a Breath Hold Time of 25 seconds or more. It works by advancing the sleeper’s lower jaw and opening the bite, which has the effect of opening the airway. Additionally, the S1 has four breathing holes at the front to regulate breathing, as well as an air spring base to cushion the jaw joint. For better retention during sleep, the patient can use the mouldable version of the S1 appliance (S1M). Progress to the S2 when the patient’s BHT reaches 35 seconds or more.


S1 Design Features

The design features of the S1 open the airway and provide comfort for the TMJs in patients with moderate BDS.

Directions for Use

The Myosa® appliance is to be used for one to two hours each day, plus overnight while sleeping. The patient's teeth may become slightly sensitive in the early stages of treatment. This is quite normal, however, if pain becomes excessive, decrease application time with the aim to build it back up once the appliance is accustomed to and sensitivity subsides. The Myosa® appliance may change the position of the teeth and jaws, though the flexibility of the appliance minimises this potential.
