Basavaraj Subhashchandra Phulari [email protected] AAccckkknnnooowwwllleeedddgggmmmeeennntttsss Writing history of the oldest specialty of dentistry and as fascinating as orthodontics at that, was a herculean task. For writing history of any field, even it requires the author/historian to be present at that specific time and place of the event that has taken place, which is practically not possible. An event of today becomes history tomorrow. As we unravel and cherish the history of yester- years, a new history would be shaping today. In the light of this practicality, I do agree that none of the chapters in the book is directly written by me. I have drawn generously from the existing literature about the subject in the form of various books, journal articles, research papers and thesis, etc. In many of the chapters, literature about a specific event or person/researcher is kept as it appears in its original literature so as to maintain authenticity and also not to inadvertently twist the history. Many of the illustrations of the orthodontic appliances and photographs of eminent researchers used in this book are facsimiles of the pictures that appear in the existing literature about the subject. I hereby humbly acknowledge all the authors of various orthodontic books, articles, thesis, seminars, etc., whose works inspired the birth of this project. The list of the literature used for the preparation of this project is given at the end of the book under the heading of suggested reading. I also gratefully acknowledge all the professors, teachers and postgraduate students of the faculty from various dental institutions in India and abroad who have contributed directly or indirectly to this exhaustive piece of work. My special thanks to my beloved wife, Dr Rashmi GS, Reader and Postgraduate Guide, Department of Oral Pathology, Manubhai Patel Dental College and Hospital and Oral Research Institute, Vadodara, Gujarat, India, for her valuable critical comments during the preparation of the manuscript, editorial assistance and proofreading. I take this wonderful opportunity to thank Dr Rajendrasinh Rathore, Chairman of Manubhai Patel Dental College and Hospital and Oral Research Institute, Vadodara, for his inspirational support during this endeavor and throughout my career. I also thank Dr Yashraj Rathore, Trustee, Manubhai Patel Dental College and Hospital and Oral Research Institute, Vadodara, for encouraging me during this project. I owe a debt of gratitude to Professor (Dr) US Krishna Nayak, Dean Academics, AB Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India, for his continuous encouragement in all my endeavors and for providing foreword to this book. I am indebted to Dr Anil Shah for all the help and encouragement I have received from him during the formation of the Chapter 7—History of Dental Lasers and their Applications in Orthodontics in the book. I extend my heartfelt gratitude to Dr Padmaja Ankit Arora for helping me with important references that were required for writing the chapters on TM Graber, James McNamara and Invisalign. My heartfelt gratitude goes to Dr Poorya Naik, Assistant Professor, College of Dental Sciences, Davengere, Karnataka, Dr Ramesh GC, Assistant Professor, Sharavati Dental College, Shimoga, Karnataka, and Dr Sujay J, Assistant Professor, SJM Dental College, Chitradurga, Karnataka, who have helped immensely in this endeavor. Exceptional efforts made the production of this book possible. I extend my special thanks to Dr Hina Desai for comments and suggestions regarding chapter on Dr TM Graber’s Contribution to Orthodontics. xii History of Orthodontics I will be failing in my duty if I do not mention the affection and support I have received from Dr Syed Zakaullah, Chairman, Al Badar Dental College and Hospital, Gulbarga, Karnataka, who has always provided that moral boost much needed during compilation of this book. My heartfelt gratitude goes to Shri Jitendar P Vij (Group Chairman), Mr Ankit Vij (Managing Director) and Mr Tarun Duneja (Director-Publishing) of M/s Jaypee Brothers Medical Publishers (P) Ltd, New Delhi, India, whose exceptional efforts made the production of this book possible.

  • Serial Extraction: Is It a Panacea for Crowded Arches?
    Review article Annals and Essences of Dentistry SERIAL EXTRACTION: IS IT A PANACEA FOR CROWDED ARCHES? * Radhika Chopra * Senior Lecturer, Karnavati School of Dentistry, Ghandhinagar ABSTRACT Serial Extraction or the guidance of eruption is an age old procedure to correct crowded arches and is still used in routine dental practice. But the efficacy of this procedure has always been controversial and it requires very precise clinical skill for a favorable outcome. This article presents a review regarding the proper selection of cases for serial extraction, its limitations and various adjuncts that are required to get good results.

  • Serial Extraction
    أ. د. أكرم فيصل الحويزي 5th Year Lec. No. 11 SERIAL EXTRACTION Serial extraction involves the timed extraction of primary and, ultimately, permanent teeth to relieve severe crowding and to guide the erupting permanent teeth into a more favorable position. It is better termed it ‘Guidance of Eruption’ or ‘Guidance of Occlusion’. Commonly at 7-8 years of age the maxillary and mandibular central incisors have erupted, but there is inadequate space in anterior segments to allow normal eruption and positioning of lateral incisors. In some cases, mandibular lateral incisors have already erupted but they are usually lingually positioned and rotated. The same is with the maxillary lateral incisors. The orthodontist has four option: Wait for growth to provide more space and re-evaluate later. Expansion of the dental arch. However, the stability of expansion may be compromised by the insufficient alveolar basal bone. Cement a transpalatal or lingual bar to preserve the Leeway space for later on. Serial extraction can reduce crowding and irregularity during the mixed dentition. HISTORY Bunon (1743) made the first reference to the extraction of deciduous teeth to achieve a better alignment of permanent teeth. In 1929, Kjellgren of Sweden first used the term ‘serial extraction’. In the 1940s, the technique was popularised in the United States by Nance who is known as the Father of serial extraction. It was advocated originally as a method to treat severe crowding by their own dentists without or with only minimal use of appliance therapy, thus minimizing demands upon the orthodontic service. Although serial extraction makes later comprehensive treatment easier and often quicker, by itself it almost never results in ideal tooth position or closure of excess space.

  • Enhancing the Predictability of Clear Aligners
    Enhancing Predictability of Clear Aligners Bowman DRASTIC PLASTIC: ENHANCING THE PREDICTABILITY OF CLEAR ALIGNERS S. Jay Bowman ABSTRACT Once limitations of clear aligner treatments were identified, conceptualizing techniques to improve the predictability in producing desired results was the next logical step. A variety of concepts, methods, and adjuncts have subsequently been introduced to enhance the efficiency and effectiveness of clear aligners. As a consequence, the scope of biomechanics and type of malocclusions that can be more predictably treated has increased. As one example, the inclusion of miniscrew temporary skeletal anchorage has permitted the addition of direct and indirect anchorage to support and control more predictable programmed tooth movements with aligners. After reviewing the reported shortcomings of plastic aligners, this chapter explores possibilities for improving predictability of aligner therapy. KEY WORDS: Clear Aligners, Miniscrews, Bootstrap Elastic, Attachments, Bonded Buttons INTRODUCTION It has been 20 years since the introduction of a commercialized clear aligner product to the orthodontic marketplace. Based on suggestion by Harold D. Kesling over 50 years earlier, Invisalign and later, increasingly numerous propriety alternatives have come to pass; including the exponential growth of so-called direct-to-consumer (DTC or DIY) offerings [1]. From the original questions of whether even “acceptable” results could be obtained from a sequence of aligners, these queries have now evolved into: Is an orthodontist even needed to be interjected between the manufacturer’s plastic and their “customers?” So, the idea of moving teeth with plastic was nothing new, but the use of software to attempt to predict desired tooth movement and the associated 3D representations of individual tooth position were innovative.

Sheldon Friel Memorial Lecture, presented 13 June 2016 at the 92nd Congress of the European Orthodontic Society, Stockholm, Sweden. Summary Background and objectives: From the beginnings of modern orthodontics, questions have been raised about the extraction of healthy permanent teeth in order to correct malocclusions. A hundred years ago, orthodontic tooth extraction was debated with almost religious intensity by experts on either side of the issue. Sheldon Friel and his mentor Edward H. Angle both had much to say about this controversy. Today, after significant progress in orthodontic practice, similar arguments are being voiced between nonextraction expansionists and those who see the need for tooth extractions in some orthodontic patients. Furthermore, varying concepts of mechanical retention of

It is followed by the extraction of certain permanent teeth to maintain the proper proportion of tooth size and dentoalveolar bone space. However, this procedure is challenging as it requires in-depth clinical knowledge and skill. This article provides essential insights to the clinicians to identify and categorize the cases meticulously for serial extraction, apply both theoretical and practical aspects of growth and development, and diagnose the alarming signs of primary crowding in early mixed dentition period.

  • Relapse of Anterior Crowding in Patients Treated with Extraction and Nonextraction of Premolars
    ORIGINAL ARTICLE Relapse of anterior crowding in patients treated with extraction and nonextraction of premolars Aslıhan Ertan Erdinc,a Ram S. Nanda,b and Erdal Is¸ ıksalc Izmir, Turkey, and Oklahoma City, Okla Introduction: The purpose of this study was to evaluate long-term stability of incisor crowding in orthodontic patients treated with and without premolar extractions. Methods: Dental casts and cephalometric records of 98 patients were evaluated before treatment (T1), at posttreatment (T2), and at postretention (T3). Half of the patients had been treated with extractions, and half were treated nonextraction. Results: Irregularity, as measured by the irregularity index, decreased 5.51 mm in the extraction group and 2.38 mm in the nonextraction group. Mandibular incisor irregularity increased 0.97 mm in the extraction group and 0.99 mm in the nonextraction group, respectively, in the postretention period. Maxillary incisor irregularity relapse was smaller than mandibular incisor relapse for both groups. Intercanine width expanded during treatment. At T3, mandibular intercanine width decreased in both groups, but the differences were not statistically significant. At T3, intermolar width was stable, arch depth decreased, overbite and overjet slightly increased, SN mandibular plane angle decreased, and incisor positions in both groups tended to return to T1 values. Clinically acceptable stability was obtained. Conclusions: With the exception of the interincisal angle, no statistically significant differences were recorded between the extraction and nonextraction groups from T2 to T3. No statistically significant correlations were found between any variables studied and mandibular incisor irregularity at T1, T2, and T3. (Am J Orthod Dentofacial Orthop 2006;129:775-84) major goal of orthodontic treatment is to arises as to which treatment procedure is most helpful achieve long-term stability of posttreatment in achieving long-term stability.
