Design characteristics of the A2

  1. Medium hardness polyurethane - provides arch development.

  2. Tooth channels - align the front teeth.

  3. Tongue tag - trains tongue position.

  4. Lip bumper - trains the lower lip.

How the A2 works

Myobrace A2
The Myobrace for Adults™ is a three-stage appliance system designed specifically to correct poor oral habits while treating upper and lower jaw development problems. The A2 provides arch development as well as habit correction and dental alignment. It is made of medium-hardness polyurethane and provides arch development and puts small force on the teeth for improved dental alignment. It is available in regular and large.

MRC has pioneered the use of appliances to correct myofunctional habits in growing children and has proven success in orthodontic correction without braces. This treatment can also lead to better facial development in growing children. The key to this treatment is correcting the position and function of the tongue, obtaining correct nose breathing and retraining the oral muscles to function correctly.

Myobrace® appliances effectively train the tongue to position correctly in the upper jaw, retrain oral musculature and exert light forces to align the teeth.

Patient Selection
The A2 is made of firm polyurethane, and is suitable for mild malocclusion. The A2‘s firm material is designed to be used after the A1, and exerts more aligning forces on anterior teeth.

Directions for use

The A2 must be worn for 1 - 2 hours each day and overnight while sleeping and always remember to follow these few simple steps:
• Lips together - at all times except when speaking.
• Breathe through the nose - to assist the development of the upper and lower jaws, and to achieve the correct bite.
• No lip activity when swallowing - which allows the front teeth to develop correctly.

Cleaning the Myobrace A2
The A2 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

The steps for correct dental and facial development are:

• Lips together.

• Breathe through the nose.

• No lip activity when swallowing.

Poor myofunctional habits such as incorrect swallowing and breathing through the mouth are the major cause of misaligned teeth and poor jaw development. Research has shown that the correction of these poor myofunctional habits improves facial and dental development.

Due to the nature of removable appliances, patient compliance is essential. Therefore it is important to only select motivated patients and parents. If motivation is a problem, it may be better to suggest the use of conventional brackets.
