Product Description

T4K Pre-Orthodontic Trainer for Kids/MRC Teeth Trainer for Open bite/T4K Red Trainer for Deep Bite


The Pre-Orthodontic Trainer for Kids™ (T4K®) is a single size, prefabricated dental appliance that incorporates both myofunctional and tooth positioning characteristics. The T4K® is designed for treatment in the mixed dentition, while the permanent teeth are erupting and the child is still growing.


1. Tooth Channels and labial bows – guide erupting teeth into correct alignment.

2. Tongue Tag – trains the tongue to sit in the roof of the mouth, improving myofunctional habits.

3. Lip bumpers – discourage overactive lip muscle activity.


The T4K®
Since first being introduced in 1992, the Pre-Orthodontic Trainer for Kids(T4K®) has become one of the most popular and successful product available from MRC. The T4K® is most effective in early mixed dentition for tooth eruption guidance and correction of myofunctional habits.

Tooth channels and labial bows guide the erupting/developing dentition into correct alignment, while the tongue tag and lip bumpers treat myofunctional habits. Starting is a soft (Silicone) Phase 1 appliance and Finishing or Phase 2 is harder (Polyurethane). It requires no impressions, no moulding, and can be applied to children from 6 years of age in minimal chair time. The T4K® must be worn for 1 hour each day and overnight while sleeping.

T4K® Phase 2 – Correcting Tooth Alignment
Once the dental alignment improves, the harder T4K® Phase 2 (pink or red) is used. This is much stiffer (same principle as orthodontic archwire). As the teeth come into place, more force can be used to encourage their alignment. The myofunctional characteristics are the same as the T4K® Phase 1. Use the finishing T4K® Phase 2 for a further 6 to 12 months. Use beyond this period is recommended depending on the outcome and the next phase of orthodontic treatment.

Patient Selection
The optimum patient age for the T4K® is 6 – 8 years of age. Although it is possible to use the T4K® in patients ranging from the primary right through to the permanent dentition, as dentition progresses the effectiveness of the T4K® as the sole method of treatment is lessened.

Direction for use

The T4K® 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 T4K®
The T4K® should be clean under warm running water every time the patient removes it from their mouth. UseMyoclean™ tablets to correctly clean twice a week. Myoclean™ is the recommended cleaning agent for MRC’s appliances.


Designed For

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


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.
