[Adult orthodontic technique: development and challenge].

Orthodontic treatments have increasingly become accepted by adults. However, the treatment therapies and philosophies for adults and adolescents have numerous differences. Orthodontic treatment for adults requires more careful planning, flexible management, interdisciplinary cooperation, and rational expectations. New techniques, such as mini-screw implants, invisalign, and self-ligating brackets, have recently been used to update treatments and widen the application of adult orthodontics by improving the treatment results. However, orthodontists still face a number of risks and challenges.
