In the recent years, number of adults seeking orthodontic treatment has significantly increased because of many factors including easier access to orthodontists, the availability of aesthetic treatment alternatives that make the appliance invisible, or improved awareness. Adults not only have malocclusions of different severity when they first arrive, but they also have additional restorative and periodontal considerations that need for interdisciplinary care that is well-coordinated. Adult patients can be divided into two groups: younger adults, who are typically under 35 and frequently in their 20s, and older adults, who are typically in their 40s and 50s. The first group looks for the most thorough orthodontic care and improvement. The second group, in contrast, pursues orthodontic treatment as an add-on technique to the significant periodontal & restorative objectives.The goal of this book is to evaluate the various adjunctive orthodontic treatment methods and their treatment sequence for adult patients. This book seeks to provide readers with a better grasp of the most recent developments in adjunctive orthodontic therapy.
