Myosa®for TMJBDS®

For adults with TMJ, breathing and myofunctional disorders

Myofunctional Research Co. (MRC) originated from the combined treatment of TMJ, breathing and myofunctional disorders over 30 years ago. Driven by an increasing patient demand for more effective treatments, coupled with the increasing frustration and confusion of practitioners with current approaches, MRC has returned to its origins with the creation of The Myosa®for TMJBDS® System, the world’s most simple yet effective treatment approach for TMJ disorders by treating the underlying breathing and myofunctional causes.

Myosa® for TMJBDS® Stage 2 - S2

Transition to nasal breathing and habit correction

The Myosa®for TMJBDS®S2is used in the second stage of treatment when the patient's Breath Hold Time (BHT) has reached 35 seconds or more. The S2 is the main appliance in the TMJBDS® range and works by advancing the lower jaw and opening the bite, which has the effect of opening the airway. It also has numerous other features which help it to treat intracapsular TMJ disorders while improving breathing and myofunctional disorders. For better retention during sleep, the patient can use the mouldable version of the S2 appliance (S2M). Progress to the S3 when the patient’s BHT reaches 45 seconds or more.

Understanding the problem

Sleep and jaw joint disorders affect a large number of the population all around the world. Most suffering patients are undiagnosed or incorrectly treated since the wide range of symptoms can make it difficult to establish the causes and appropriate treatment. Symptoms such as headaches, neck pain, night-time snoring and daytime fatigue may seem unrelated. However, they can all be a part of a single health problem. Quite often these problems occur simultaneously because two of the causes of TMJ/D are mouth breathing and incorrect swallowing habits.

Normal nose breathing vs mouth breathing

Mouth breathing is abnormal and is one of the causes of Sleep-Disordered Breathing(SDB) problems. If a child breathes through the mouth, the jaws will not develop forwards correctly. Adults who have SDB will usually have underdeveloped jaws, which cause the tongue and lower jaw to restrict the airway. Therefore it is important to learn how to breathe correctly through the nose at all times in order to maintain an advanced position of the lower jaw and tongue, as well as keeping the airway open.

Treatment with oral appliances

The Myosa®program involves specific evaluation, diagnosis and treatment phases to identify the presence of Sleep-Related Breathing Disorders(SRBD) and Temporomandibular Joint Disorders(TMJ/D).These disorders are interrelated and have been combined into one collective syndrome known as TMJBDS-symptoms relating to Teeth, Muscles, Jaws, Breathing and Disordered Sleep. Along with providing rapid symptom relief, the Myosa® program facilitates treatment specifically designed to address the root causes of the problem. The Myosa®program aims for complete symptom resolution, although results may vary with each individual.

S2 Design Features

The design features of the S2 open the airway and improve TMJ symptoms, especially intracapsular disorders, in patients with mild to moderate BDS.

lHigh sides provide good retention without moulding.

l4 small breathing holes at the front which are designed to encourage nasal breathing while still allowing mouth breathing.

lTongue tag guides the tongue forwards and upwards into the correct position.

lTongue elevator holds the tongue in the correct position.

lSoft flexible material allows lateral movement making the Myosa® S2 more comfortable than rigid devices.

l4 small posterior holes open the airway and provide comfort for the jaw joints by allowing vertical movement, which decompresses the jaw joints and reduces clicking.

The Myosa®S2 can be used after treatment with the Myosa® S1 to assist in treating Sleep Disordered Breathing (SDB)

Myosa® S2 - Stage 2

Myosa® for TMJBDS® S2 is designed for patients who are not chronic mouth breathers or who have already undergone Stage 1 treatment with the S1 or S1Mappliance.The Myosa® S2 works by advancing the sleeper's lower jaw and opening the bite, which has the effect of opening the airway. The smaller breathing holes at the front of the appliance optimise breathing regulation by encouraging nasal breathing and lip seal maintenance. For better retention during the night, the patient can use the mouldable version of the S2 appliance (S2M), which provides a tighter, custom-fit due to its dual moulded construction.

Indications for use:

Prior to using theMyosa® device, the treating dentist may refer the patient to a medical practitioner for assessment of sleep disorders that have medical implications. The Myosa® intra-oral appliance provides treatment for patients with symptoms of TMJBDS® and is to be used during the day until comfort is achieved. Once accustomed, it should be used for 1 hour per day and overnight while sleeping.

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.
