“This is a great textbook, and I will use it in my classes.  Highly organized and elaborately illustrated, the authors’ work is inspired by problem-based learning and stimulates cognitive processes by encouraging critical thinking.  Their text deserves a ‘must read’ category for orthodontic professionals of all ages.”Dr. Jeryl D. English DDS, MSChairman and Graduate Program DirectorDepartment of OrthodonticsThe University of Texas Health Science Center at Houston  “A terrific book for students of orthodontics and dentofacial orthopedics, covering the vertical dimension and much more.  A wide range of cases are presented, treatment plans are realistic, and the authors openly discuss complications encountered during treatment.”Dr. Greg J. Huang, DMD, MSD, MPHProfessor and ChairDepartment of OrthodonticsThe University of Washington School of Dentistry  “This comprehensive text prepares the reader in the context of a mini-residency with a question-answer teaching style.  Resident and experienced orthodontists can match their cases with fully worked up patients and alternative treatment options.  Well written.”Dr. Katherine L. Vig, BDS, MS, FDS, D.OrthProfessor Emeritus and Former Head of OrthodonticsThe Ohio State University College of Dentistry"The profession of orthodontics is largely a discipline of observation, reasoning, and decision-making. This book aims at strengthening those in-treatment decision abilities. It is perfect both for orthodontic residents just learning their technique and for experienced clinicians interested in improving their proficiency. I promise it will be one of the most remarkable books you have ever read."Journal of Clinical Orthodontics March 2016
