Design characteristics of the K1 Broad

  1. Flexible material - for use in more extreme starting cases and for improved patient compliance and comfort.

  2. Patented Broad design - specifically for broader arch forms.

  3. Tongue tag, guard and elevators - train the tongue to position properly.

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

How the K1 Broad works

Myobrace® K1 Broad
The Myobrace® for Kids – Broad appliance series is a three-stage system with a specialised arch form for specific genetic and racial groups. This wider arch form is prevalent in many Asian countries, as well as Central and Latin American groups. The appliance is characterised by its flatter anterior arch form with wider canine area, and a more flared posterior arch form. Ultimately, the natural arch form is determined by the tongue position and the K Broad series treats breathing, corrects tongue positioning and arch form.

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 nasal 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 Kids - Broad is best used after the permanent front teeth have come through (ages 5 to 10) and before all adult teeth have developed at ages 12 and older. Only available in medium and large.

Directions for use

The K1 Broad 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® K1 Broad
The K1 Broad 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.

Arch Expansion

In more severe cases when the jaws are under developed, appliances such as the Farrell Bent Wire System™ (BWS™) and/or  Biobloc may be required for extra widening of the dental arch form. An advantage of using the BWS™ is that it can be using in conjunction with the K1 Broad. MRC have also developed a procedure for composite build ups know as Myolay™.
