I was very flattered having received the invitation to preface this book. After reviewing its contents, I wish to take this opportunity to thank each of the authors who have contributed so magnificently to the orthodontic literature.
Orthodontic management of the Class III malocclusion has been a genuine challenge to the profession and remains a controversial issue among clinicians and researchers. Some support the dictum that growth and size of the craniofacial complex are genetically predetermined and cannot be altered. They assume that the great majority of Class III cases are “untreatable” by orthodontics alone, and that surgical management after growth has been completed is inevitable. Others agree that heredity plays a major role in this type of deviation, yet support the contention that the pattern and direction of growth can be modified and that forces generated in orthopedic and orthodontic treatments are able to minimize and even successfully correct some Class III malocclusions. The controversy is real and one question still to be answered: How much can orthodontics really do?
Orthodontic Treatment of Class III Malocclusions helps to answer many questions and leads to fascinating suggestions for more research. It is truly an indoctrination of the very basic issues of growth and development and the influence of heredity in the growing and non-growing patient. Skeletal anchorage devices, surgical protocols, lingual orthodontics and a very interesting chapter on cleft lip and palate patients can be found in the text. All the material presented is well anchored on scientific and clinical evidence.
As an academician who has devoted a great deal of time to Class III treatment, I would say that this text is a great addition to the literature, reinforcing and supporting the premise that appropriate interventions at the proper time, accompanied by a family growth study may very well minimize or camouflage the Class III to acceptable and stable results without surgical intervention. There is clinical and scientific evidence that selected procedures can change questionable prognoses.
And yet, with the introduction of the vast amount of new knowledge promulgated by the most recent research; the many authors, in their brilliant presentations offer evidence that the influence of skeletal anchorage, early intervention and heredity can certainly help the orthodontist make a more cogent decision in the ultimate treatment plan for the patient with the disfigured countenance.
Yes, indeed, this is a book packed with nuggets, and well worth reading.

This new eBook is a clinical text with plentiful illustrations to highlight both research findings, as well as clinical treatment of patients with Class III malocclusions. In addition, the craniofacial biology behind the various treatment strategies will empower clinicians with a sound knowledge for treatment of Class III problems. Contemporary orthodontic appliances, using micro-implants as anchorage, provide new avenues in the treatment of Class III patients. This text has appeal for both academicians and clinicians, but the targeted readership involves all practicing professionals in the field of orthodontics globally. The prevalence of Class III malocclusion is higher in Southern Asia countries. The international expertise addressing this important clinical area will be particularly appealing to clinicians throughout the world where there is a high influx of Asians with Class III malocclusions.
This book is broadly divided into five parts. Part I of the book introduces the Class III skeletal growth pattern and the genetics of mandibular prognathism. Since chincaps, facemasks and Class III elastics are routinely used for modifying Class III growth patterns, it is appropriate to update the readers on the biologic response of the mandibular condyle to orthopedic/orthodontic forces. Part II focuses on the diagnosis and treatment of Class III malocclusions in the growing patients. There are three main treatment options for skeletal Class III malocclusion: growth modification, dentoalveolar compensation, and orthognathic surgery. The authors present guidelines for choosing among these treatment options. The emphasis is on the discriminative diagnosis and the characteristic procedures of each treatment option. A systematic review on the current literature on the stability of early treatment was included and a novel approach for using micro-implants for early orthopedic treatment was introduced. Part III focuses on the diagnosis and treatment of Class III malocclusion in nongrowing patients. This part introduced the use of self-ligating bracket system and temporary anchorage devices (TAD) to camouflage adult patients with mild to moderate Class III malocclusion. The use of TAD facilitates the treatment for specific types of Class III malocclusion and expands the range of orthodontic camouflage treatment. Patients with severe Class III malocclusion will require orthognathic surgery to correct the deformity. A significant number of these patients have mandibular asymmetry. The authors will present a contemporary way to treat these patients with combined orthodontics and orthognathic surgery. Part IV provides plentiful illustrations to guide the readers on the treatment of non-growing Class III patients, with camouflage to lingual treatment. The last portion of the text provides clinical insight and concerns relative the treatment of dentoalveolar craniofacial anomalies. The emphasis is on the scar-associated physiological and developmental problems that plague the orthodontic treatment of cleft lip and palate orthodontic patients. We would like to thank Dr. Araujo Eustaquio for writing the foreword and Bentham Science Publishers, particularly Manager Publication Aniza Naveed, for their support and efforts.
