Open-Bite Malocclusion: Treatment and Stability presents the etiology, treatment, and its stability of anterior open bite malocclusion in the early, mixed, and permanent dentitions. Special emphasis is devoted to orthodontic treatment and its stability in the permanent dentition because this is the time when treatment of open bite presents greater relapse. Appropriate for clinicians, orthodontic residents, and dental students, Open-Bite Malocclusion covers the most simple treatment approaches to the most complex, from orthodontic devices to tooth extraction to surgery.

Open-Bite Malocclusion: Treatment and Stability presents the etiology, treatment, and its stability of anterior open bite malocclusion in the early, mixed, and permanent dentitions. Special emphasis is devoted to orthodontic treatment and its stability in the permanent dentition because this is the time when treatment of open bite presents greater relapse. Appropriate for clinicians, orthodontic residents, and dental students, Open-Bite Malocclusion covers the most simple treatment approaches to the most complex, from orthodontic devices to tooth extraction to surgery.
Unique to this book is the discussion of post-treatment stability. Drs. Janson and Valarelli highlight the post-treatment changes and presents strategies to increase treatment stability. This allows the clinician to be able to predict the stability probabilities when treating anterior open bite malocclusions in the permanent dentition either with or without extraction, orthodontic-surgical therapy, or with occlusal adjustment.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
Dr. Guilherme Janson is Professor of Orthodontics at Bauru Dental School, University of São Paulo, Brazil. His three primary lines of research are asymmetric malocclusions, efficiency of Class II malocclusion treatment protocols, and stability of open bite treatment. He has authored and co-authored more than sixty peer-reviewed journal articles on these subjects. Dr. Fabricio Valarelli is Associate Professor of Orthodontics at Ingá Dental School, Maringá, Paraná, and has a private practice in Bauru, São Paulo, Brazil. He is especially interested in clinical research, focusing on Class II and anterior open bite malocclusion treatment and their stabilities.
