Researching orthodontics on the internet may be difficult for parents. There are many orthodontic offices and companies providing information about braces. The American Association of Orthodontist provides a good start at their website www.mylifemysmile.org
Questions? When do we start treatment? Extraction vs non extraction? Which type of braces/wires are used? Which treatment plan is best? Adult treatment?
Research in orthodontics is important to answer these questions. Good research is even better. Many research articles are published but only a few get selected for an orthodontic journal. The American Journal of Orthodontics & Dentofacial Orthopedics (AJO-DO) and The Angle Orthodontist are my favorite. The Angle Orthodontist at www.angle.org is free on the internet. This is a good place to search for questions about orthodontic treatment.
I also would visit www.kokichorthodontics.com . Dr Kokich Jr. has many great articles to read about adult orthodontics that are provided for free on his website.
