Open-Bite Malocclusion: Treatment and Stability presentsthe etiology, treatment, and its stability of anterior open bitemalocclusion in the early, mixed, and permanent dentitions. Specialemphasis is devoted to orthodontic treatment and its stability inthe permanent dentition because this is the time when treatment ofopen bite presents greater relapse. Appropriate for clinicians,orthodontic residents, and dental students, Open-BiteMalocclusion covers the most simple treatment approaches to themost complex, from orthodontic devices to tooth extraction tosurgery.
Unique to this book is the discussion of post-treatmentstability. Drs. Janson and Valarelli highlight the post-treatmentchanges and presents strategies to increase treatment stability.This allows the clinician to be able to predict the stabilityprobabilities when treating anterior open bite malocclusions in thepermanent dentition either with or without extraction,orthodontic-surgical therapy, or with occlusal adjustment.
