MRC Trainer T4A for Alignment

How the T4A Phase 1 works

The T4A is like the T4K? but designed for the permanent dentition. It has higher sides in the canine region to align erupting canines and the distal ends are longer to accommodate the second molars. The combination of labial bows and tooth channels with the 2 phase hardness, polyurethane material, give good alignment of anterior teeth. The Myofunctional Effect also retrains oral musculature making it ideal in retention and minor relapse cases. The T4A is made of polyurethane and is available in two versions – Phase 1 (softer version) and Phase 2 (harder version).

T4A Phase 1 (Starting)

The Phase 1 T4A (blue or clear) is a softer material with the flexibility to adapt to misaligned anterior teeth. When used, light forces are applied to the anterior teeth to assist their alignment into the correct arch form. The T4A Phase 1 can also be used simultaneously with specific arch development appliances. Extra spacing in the palatal area means it can be used with the BENT WIRE System (BWS and also MRC’s Myolay arch-development system.

Combined with the myofunctional habit correction of the T4A these light intermittent forces produce dental alignment improvements within 3-6 months.

T4A Phase 2 (Finishing)

Phase 2 T4A (red) is the same design but made in a harder material putting more force on the anterior teeth. It is to be used after the phase 1 T4A once more aligning force is required. This further improves the tooth and Class II correction (minor) while continuing the myofunctional habit correction. It can be phased into use starting with 1-4 hours during the day while continuing with the softer starting T4A at night. Treatment period varies and can be a further 3-6 months plus retention.

Patient Selection

The T4A is best suited to patients 12 – 15 years of age in the early stages of the permanent dentition. The T4A can be used as a myofunctional retainer for patients who do not wish to have permanent bonded retainers fitted. It is also useful for treating minor relapse cases without re-fitting fixed orthodontics, and for minor cosmetic alignment of the anterior teeth.

Direction for use

The T4A 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 T4A?

The T4A? should be clean 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.
