Written by a team of renowned experts in the field, »Dentofacial and Occlusal Asymmetries« will serve as an invaluable resource to postgraduates in orthodontic, pediatric dentistry and oral and maxillofacial surgery programs as well as orthodontists, pediatric dentists, pediatricians and oral and maxillofacial surgeons aiming for optimal results in the diagnosis and management of these complex malocclusions and dentofacial deformities.
Birte Melsen is the past President of European Orthodontic Society in 2004 and has made significant contributions to the field of orthodontics with her research, publishing around 350 papers in scientific journals on topics related to anchorage (orthodontics) and adult orthodontics. She is currently an orthodontist from Denmark.
