Design characteristics of the T4

  1. Firm polyurethane construction - provide excellent retention.

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

  3. Extended lip bumper and high sides - discourage strong, overactive lips and facial muscles.

How the T4 works

Myobrace T4

The T4 provides final alignment of the teeth and jaws. Its firm polyurethane construction also provides excellent retention. The hollow tongue tag encourages final tongue position. The T4 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 Myobrace for Teens™ is most effective when a patient has most of their permanent teeth (ages 10 to 15) and is available in a range of sizes.

Directions for use

The T4 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 T4
The T4 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.

Appliance use

Designed For

• Class II Division 1 + 2 malocclusion
• Anterior (upper + lower) crowding
• Deep bite
• Open bite


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.
