Ortodoncia lingual: Procedimientos y aplicación clínica

Julia Harfin and Augusto José Ureña Rodríguez wrote their recently published text, Ortodoncia lingual: Procedimientos y aplicación clínica , in Spanish. With the popularity of clear aligner therapy, clear brackets, and a desire for more esthetic treatment options, it is a welcome addition that gives the reader a well-organized book with many color photos, illustrations, and useful information backed up by literature. This text is organized into 13 chapters. Each chapter starts with an introductory history and review of the pertinent literature elaborated with clinical cases. The patients are all presented with treatment plans and objectives along with color photos of the initial presentation, progress images, and final photographs.

The initial chapter covers clinical and laboratory procedures used in lingual orthodontics. The type and placement of brackets as well as indirect bonding are discussed. The archforms used in lingual archwires and how to ligate these to the brackets and the bends for canines and molars are thoroughly reviewed with many color photos. The 3 phases of treatment—initial leveling and aligning, space closure and root alignment, and finishing—are also reviewed. Concluding this chapter is a section of clinical pearls that are helpful in addressing the challenges of lingual orthodontics.

The importance of the soft-tissue papilla in obtaining an esthetically pleasing outcome is the topic of chapter 2. The authors reviewed the literature, which shows that the level of bone dictates the level of the soft tissues, and how these relate to the treatment of diastemas. Chapter 3 covers a problem that affects almost 80% of the population: mandibular incisor crowding. The different types of crowding and the studies by Sinclair, Riedel, and Little are reviewed. The various treatment options to address this problem, from interproximal reduction to extraction of teeth from incisors to premolars, are nicely summarized.

Correction of Class II malocclusions in nongrowing patients is the subject of chapter 4. Biomechanics, anchorage control, extractions, and use of elastics in Class II treatment are all reviewed. Chapter 5 discusses the pendulum appliance in conjunction with lingual orthodontics to address mesially drifted and rotated maxillary molars. The nonsurgical treatment of Class III malocclusions is the subject of chapter 6. The different types of Class III patients and the cephalometric analysis of both hard and soft tissues are covered.

In chapter 7, the treatment of deep overbites is explored. Treating these patients with lingual orthodontics offers some advantages with bracket occlusal interference by passively extruding the posterior teeth. In chapter 8, appropriately titled “A chapter never before thought of,” the authors show how lingual orthodontics can be used in growing patients with interceptive treatment and functional appliances.

A challenging malocclusion encountered in orthodontics—open bite—is the subject of chapter 9. The biomechanics used as well as the placement and use of elastics are demonstrated. In chapter 10, unconventional treatments such as canine extractions and treatment of cleft lip and palate patients are shown.

Chapter 11 covers the effects of the oral environment on the dental materials we use in orthodontics. The different ways a material can be affected, from corrosion, wear, and pigmentation, to the effects of water absorption are covered.

As with all orthodontic treatments, the topic of retention is always important and is covered in chapter 13. The authors present their retention protocol along with photos illustrating their techniques for fixed retention. The final chapter is dedicated to the key elements in achieving success in lingual orthodontic treatment.

This book is appropriate for anyone wanting to practice lingual orthodontics. It is nicely illustrated with many color photos demonstrating the mechanics and techniques, making it easy for the reader to understand the concepts. These concepts are integrated with the clinical cases used to demonstrate the ideas of each chapter. Each patient has a treatment plan, and the treatment objectives are carefully explained so that the reader can apply the ideas in clinical practice. The authors did a wonderful job in this evidence-based text, with an appropriate review of the literature and a bibliography at the end of each chapter. If you plan to utilize this technique, which is popular in many countries, or if you are just interested in offering more esthetic orthodontic options to your patients, this book is a must-have for your library.
