With the advances in clear aligner therapy, we can treat most maloccusions with Invisalign orthodontics. Align Technology (the Invisalign company) spends much money on research and has developed many new attachments, techniques, and aligner materials. As a result, Invisalign can correct most orthodontic problems. With the new aligner material, the wearing time for each aligner has decreased from 14 days to 7-10 days.
