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. Phase 1 medium (hardness) Phase 2 harder (both polyurethane).

TWO PHASE system
The T4A™ is made from super elastic, high memory polyurethane material. This allows adaption to the patient’s arch form without special fabrication. The material imparts a light force on misaligned anterior teeth similar to the action of arch wire.
Phase 1 (Starting) T4A™
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 Crozat, LAD, Q-Helix and BWS™ (BENT WIRE System™ – see video) appliances. Combined with the myofunctional habit correction of the T4A™, these light intermittent forces produce dental alignment improvements within 3-6 months.
Phase 2 (Finishing) T4A™
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.
