Summary:

Despite a great increase in the use of fixed appliances, the majority of courses of orthodontic treatment are still carried out using removable appliances. This practical guide contains essential information on the design and construction of removable appliances, in addition to guidance on diagnosis and treatment through the use of clinical case studies. Written by three leading authorities in the field, Removable Orthodontic Appliances contains relevant, up-to-date information making it an invaluable purchase for all dental undergraduates, practitioners involved in orthodontic treatment and dental technicians.
