Design characteristics of the B3

  1. Widened Channels - to accommodate clear aligners.

  2. Tongue tag, tongue guard and elevators - trains the tongue to sit in the correct position in the upper jaw.

  3. Extended lip bumbper and high sides - discourages overactive lip function and encourages nasal breathing.

How the B3 works

Myobrace® B3

MRC has pioneered the use of appliances to correct myofunctional habits in growing children and improve the success of orthodontic correction. This involves correcting mouth breathing, tongue position and swallowing patterns, which can lead to better facial and arch development in growing children.

Myobrace for Braces™ is used to correct these myofunctional habits in combination with braces and helps expand jaws and align the teeth more easily.

Goals of treatment

• Lips together at all times except when speaking or eating.

• 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.

• Improved dental alignment.

• Improved facial development.

For the Myobrace® to work, you must correct your poor myofunctional habits.

Myobrace for Braces™ is a three-stage appliance system specifically designed to be compatible with braces while correcting poor oral habits, improving upper and lower jaw developmental problems and assisting fixed appliances to align permanent teeth.

These appliances correct poor myofunctional habits, which can cause crooked teeth, while providing light forces to assist in expanding the upper jaw and help braces align teeth into the correct position.

Treatment considerations

Treatment time can differ depending on the biological adaptability of each patient. The Myobrace® appliance must be used daily for a successful outcome.

Regular monitoring by your dentist or orthodontist is essential for successful treatment and to avoid unwanted treatment outcomes.
