For my father and mother,
who taught me about intellectual integrity,
which is the cornerstone of this book.
For Stefano and Federica, for putting up with such a “busy mom.”

This book's uniqueness lies in the fact that it studies malocclusion from a gnathological viewpoint, in terms of both diagnosis and treatment. The study of masticatory function includes gnathological principles that allow us to understand the functional aspects of malocclusion conditions and their effects on the entire stomatognathic system. A gnathological approach helps us understand the importance of selecting and applying treatments which respect overall physiological wellbeing.
Indeed, it is only through balanced and harmonious function that a developing system may grow healthily from a neurophysiological perspective, avoiding impairment and maintaining these results constantly throughout adulthood. Therefore, the final goal of early orthognathodontic treatment is to achieve (via the teeth) a rebalancing of function by following gnathological principles. The study of theories forwarded by respected scholars (from Gisi onwards) of the structure and function of the masticatory system and craniomaxillofacial area was extremely important for us.
During our studies we had the chance to understand the works of, as well as spend time with, B. McCollum, Ch. Stuart, H. Stallard, and P. K. Thomas (nicknamed “the immortals of Loma Linda University”), along with R. Lee, S. P. Ramfjord, T. Lundeen, and B. Jankelson. A special mention goes to R. Slavicek of the University of Vienna and A. Lewin of the University of Witwatersrand in Johannesburg, South Africa. The ideas and teachings of these scholars (on whose work our own is founded) were fundamental in the writing of this book about crossbite, thanks to their smart understanding of the risks and collateral effects as well as neuromuscular implications of the condition.
This is a matter studied and discussed by many but still deserving of further research, owing to the important and irreversible gnathological implications that we have learnt to identify thanks to the aforementioned experts. The knowledge gathered by research into mastication and then applied to the use of orthognathodontic devices before/after treatment has been essential in understanding the effect of occlusion on chewing cycles and the importance of respecting gnathological principles when selecting therapies.
The understanding and respect of these principles allowed the perfection over time of a therapy that for many years gave even better results than we could have predicted. Thanks to the study of masticatory function, many of these results became clearer, and they are described in this book in a precise and logical way (despite the complexity of the topic).
The project was not easy, and is the result of many years of research into the fields of orthognathodontics and masticatory function. I hope, above all, that this book can spark a change, a move towards a gnathological approach in the diagnosis and treatment of malocclusions, in light of the fact that the true goal of a medical dentistry field like orthognathodontics should be the functional balance and harmony of the stomatognathic system.
