Design characteristics of the J2

  1. Medium-hardness material - for improved arch development.

  2. Hollow tongue tag; tongue guard and elevators - train the tongue to sit in final correct position and prevent thumb sucking.

  3. Breathing holes - assist the transition to correct nasal breathing.

  4. Extended lip bumper - discourages strong, overactive lip muscles.

How the J2 works

Myobrace J2
The Myobrace for Juniors™ is a three-stage appliance system designed specifically to correct poor oral habits while treating upper and lower jaw development problems. The J2 provides arch development as well as habit correction and is made of medium-hardness material which assists in widening and developing the jaws. The J2 is a single-size appliance available in pink and blue.

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 Myobrace for Juniors™ is most effective in the primary dentition from as early as three years of age.

Directions for use

The J2 must be worn for 1 hour 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 J2
The J2 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.
