Invisalign First

Patient Chief Concern
crowding of lower anterior teeth

What learning would you share with other Invisalign providers?
Invisalign technique can achieve arch expansion up to 3mm , which is suitable for severe crowding cases caused by dental arch narrow during growth and development periods. 2、If the teeth are completely located outside the dental arch, the use of invisalign clear aligners can incorporate malposition of the teeth into the dental arch and arrange them , reducing the discomfort of patients because of using other assistive devices.3、When the arch expansion is more than 3mm, the posterior teeth can be overcorrected to increase the lingual torque 5 to 8 degrees to prevent the buccal tilt of the posterior teeth and open bite.

What contributed most to this treatment being successful?
The optimized expansion support attachment effectively realized the expansion of the upper and lower dental arch，created a aligned space for the severely crowded lower anterior teeth and align mandibular midline with maxillary midline . Moreover, because of the digital and personalized design properties of the invisalign，the 42 eruption compensation can be adjusted automatically according to the movement of the teeth, so it not only can create space for the 42 eruption but also can guide the 42 to the dental arch.so, no other auxiliary means are used throughout the clinical process, and finally achieved the ideal correction effect. Optimized retention attachment and added the root tongue torque prevented the the molar teeth open bite or palatine tipping ptosis, the occlusal was tight after the end.
