This is the first edition of a comprehensive textbook written by Dr Guilherme Janson, Professor of Orthodontics at Bauru Dental School in Brazil, and Dr Fabrico Vlarelli, Associate Professor of Orthodontics at Ingá Dental School, Brazil. The extensive research experience of both authors, focusing on open bite and Class II malocclusions, speaks volumes for the credibility and quality of this publication.

Following the first chapter, which is an outline of both genetic and environmental aetiological factors concerning open bite malocclusions, the remaining four chapters discuss treatment options in order of ascending difficulty, finishing with a chapter on surgical options. The distress caused to both patient and clinician by relapse along with the importance of considering the stability of any treatment plan, particularly in these challenging cases, is clearly acknowledged in this book with each chapter finishing with a section on the stability of the discussed treatment modalities.

The core two chapters of the book look at open bite treatment, first in the deciduous and mixed dentition and then the permanent dentition. Cases are beautifully illustrated with colour photos taking the reader through each stage of treatment. In fact, practically every point made in this text is demonstrated with a reference, figure or illustration making even complex topics an easy read.

The entire book is heavily evidence based, with references both embedded in the text and listed as an aid for further reading at the end of each chapter. The references include not only the most up to date publications on relevant topics but also important landmark papers.

In conclusion, the comprehensiveness of this book, although impressive, targets it towards the experienced orthodontic trainee, specialist or consultant as opposed to students or general dental practitioners. Undergraduate curriculums tend to only touch upon open bite treatment in the deciduous or mixed dentition whereas treatment in the permanent dentition and surgical options are usually topics for the qualified, specialist clinician. For these practitioners, this textbook would be a valuable and enjoyable read.
