The A1 provides habit correction and initial dental alignment. The A1 is made of soft and flexible material to adapt to a wide range of arch forms and poorly aligned teeth. The soft material allows for better retention and comfort in the initial stages of treatment.
The B3 provides habit correction in the retention phase. It features a widened channel, tongue tag, tongue guard, elevators, extended lip bumpers and high sides to correct tongue position, discourage overactive lip function and encourage nasal breathing in conjunction with clear aligners.
