DESIGN CHARACTERISTICS OF THE T4A™ PHASE 2
High sides - guide erupting canines.
Tongue tag - trains the tongue to sit in the roof of the mouth, improving myofunctional habits.
Tooth aligners - impart a light force on misaligned teeth.
HOW THE T4A™ PHASE 2 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. TheMyofunctional 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 or clear) 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.
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. UseMyoclean™ tablets to correctly clean twice a week. Myoclean™ is the recommended cleaning agent for MRC's appliances.
