In the endeavor to provide beautiful smiles to the patients, an Orthodontist is blessed with a wide array of fixed appliances that can be used, although often times this may turn out to be a bane due to lack of consensus and scientific evidence, as to which appliance truly works the best. This book provides an in-depth analysis and understanding of the efficiency of three commonly used fixed orthodontic appliances - Pre-adjusted edgewise, Tip-edge and Begg - in the treatment of Class I Bimaxillary Protrusion cases. The book features description of the three appliance types, characteristics of bimaxillary protrusion cases, dentoalveolar and soft-tissue changes produced by fixed appliances, measurement of incisor intrusion and molar extrusion using Centroid analysis and a detailed discussion on the ICON Index devised by Richmond & Shaw with respect to Bimaxillary protrusion cases . The book can be particularly useful to Orthodontic practitioners, academicians, researchers & students interested in gaining new perspectives and understanding the working and clinical efficiency of the fixed orthodontic appliances, while discovering the methodology of a research study to do so.
Achievement of stable results is one of the most important goal of orthodontic treatment beyond facial and dental aesthetics, function, health and longevity of the dentition. Over the years retention as a separate phase of orthodontic treatment was largely neglected and therefore clinicians had to face the wrath of relapse of their corrections. A steady evolution in the importance of the retention and appliances has been observed over the last 50 years. Retention appliances have transformed from the bulky, acrylic removable appliances towards the more aesthetic and comfortable invisible retainers, Essix retainers and the fixed bonded retainers. A multitude of factors responsible for post-orthodontic relapse have been recognized by various authors. Hence the orthodontist should be meticulous enough in planning retention and stability of the post-treatment results right at the binging of the treatment itself.
Fixed Functional appliances have been used since the nineteenth century. By using functional appliances in conjunction with fixed appliances and extra-oral forces, best possible results for a patient can be accomplished with less possibility of problems and greater long-term stability, a stability that depends on the balance of teeth, bone and muscle achieved during the treatment. An update review on Fixed Functional Appliances and philosophy behind their modus operandi is presented in this book. Various appliances are discussed with illustrations. This book will provide Clinical Orthodontists with Secrets of Manipulation and Construction of various Fixed Functional Appliances. An updated review on this subject is presented for benefit of postgraduate students also.
