Description
Book SynopsisUnilateral posterior crossbite is a problem often seen in orthodontic practice, and properly understanding chewing patterns will lead to the most effective treatment program. Drawing on their research and available literature, Drs.
Trade Review"I would highly recommend this book to postgraduate students, specialists in orthodontics, pedodontics, and stomatognathic physiology, and general dentists. It can be a great reference for anyone treating a young patient whose teeth may be developing in a questionable position." (
