Typically using conventional braces may be slower vs clear aligners ie) Invisalign. However with the new ADA approved Orthodontic Accelerated methods it can be up to 50% faster. To answer your question, we may be able to use Invisalign and it may take 11-15 months; if Accelerated Orthodontic device is used, we can cut that time in half!! Of coarse we would have to do a proper screening and examination to make sure you are a good candidate for either treatment.
I am sure your final results will look fantastic!
All the best,
