Design characteristics of the S3

  1. Lower sides provide good retention for established nasal breathers.

  2. 2 small breathing holes designed to maintain nasal breathing.

  3. Tongue tag maintains the tongue in the correct forwards and upwards position.

  4. Tongue elevator holds the tongue in the correct position.

  5. Flexible material for improved patient compliance and comfort.

  6. Thinner base provides optimal jaw position and normal vertical opening.

How the S3 works

Myosa® for TMJBDS® S3 is made from medical grade silicone and is designed for patients who have progressed through previous stages of Myosa® treatment and largely corrected their mouth breathing habit. The S3 provides less advancement of the lower jaw and a thinner base for less vertical opening. This helps the patient transition to normal jaw positioning and vertical opening. The S3 is used once nasal breathing has been established and symptoms of TMJBDS® are greatly reduced. It is commonly used in conjunction with Myotalea® appliances to strengthen the tongue and lips to improve nasal breathing and correct poor oral habits.

 

Patient Selection
The TMJBDS® appliances are used based on a combination of the patient's ability to retain the appliances overnight, severity of their breathing dysfunction and their performance of Breath Hold Time activity (BHT). The S3 - is used in the third stage of treatment when the starting BHT is 40 or more. The non-mouldable S3 appliance provides optimum comfort and retention for patients who have established nasal breathing. Auxiliary appliances that aid treatment are based on the level of the patient's joint degeneration and serve as adjuncts to the use of the TMJBDS® appliances. The full protocol is outlined in MRC's courses and attendance is highly recommended. Additionally, you can download the Myosa® appliance protocol.

 

Indications for use
Prior to using the Myosa® 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.

 

Instructions for use

Do not chew on Myosa® appliance. Initially use the S3 during the day to correct habits.
 

Cleaning the S3 appliance
The S3 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.

Important Points

Intra-oral appliances may change the position of teeth and alter the jaw relationship. Unlike Rigid Mandibular Advancement Devices (MADs), the Myosa® appliances are flexible and minimise the potential to cause pain in the jaw joints or permanently change the bite.

Consultation with a Medical Practitioner is essential to correctly evaluate your condition.
