With the intention of improving the rate, quality, and stability of orthodontic tooth movement, those in the field are now moving toward accomplishing this 'acceleration' with minimally or non-invasive methods. New procedures have been widely tested in humans, animal models, and in vitro. While interest is growing both in the industry and at the clinical level, the understanding of the biology is limited. Considering that a simple increase in force will result in tooth morbidity and arrest of the tooth migration, a multi-disciplinary approach is critical for success. This publication brings together multi-disciplinary expertise on a wide variety of processes related to and involved in orthodontic tooth movement. The premise is that, by better understanding the biological structures and the mechanism through which they respond to biomechanical forces, one can get a better assessment of the 'acceleration'. This work presents research aimed at an improved understanding of conventional and accelerated orthodontic tooth movement from a biological perspective and will be of great value to clinicians, researchers, academics, and students.

The interface between orthodontics and periodontolgy is as broad as any between two disciplines in clinical dentistry. Controlled tooth movements utilize the dynamic nature of the periodontium which remodels actively when external forces are applied. Periodontal tissues are also continuously at risk from plaque-induced diseases that compromise the support of the dentition. The accumulation of plaque is enhanced when patients wear orthodontic appliances and the dental hygienist has a vital role to play before, during, and after orthodontic treatment. Changes in tooth relationships are often a consequence of periodontal disease. When the condition has been controlled orthodontic treatment may be indicated to, for example, align drifted incisors, or to upright molars that have tipped into extraction spaces. The objective of this book is to explore fully the interrelationships between the periodontium in both health and disease, and orthodontics. It is not a text that is aimed purposely towards the specialist management of orthodontic or periodontal cases. We have instead examined exhaustively the common ground upon which the orthodontist and periodontist are often called upon to meet and collaborate on cases that demand multi-disciplinary care. The text is presented in two parts. Part I comprises three chapters covering the basic sciences. Chapter 1 deals with the anatomy and physiology of the peridontium and investigates the role of dental anatomy in the initiation and progression of periodontal disease. Chapter 2 summarizes the microbiology and pathogeneisis of periodonatla disease and it is evident that many of the biological mediators which are involved in the perpetuation of disease are also implicated in the day-to-day remodelling of the supporting tissues. Chapters 3 studies the histological aspects of orthodontic tooth movements and looks at the biological mechanisms involved. Part II comprises the remaining six chapters. Chapter 4 discusses the exmaination and treatment planning for the orthodontic management of patients who have a history of periodontal disease. Chapter 5 deals with different concepts of occlusion and how common occlusal problems can initiate periodontal problems. The importance of controlling periodontal disease before orthodontic treatment is explained in Chapter 6. Aids to oral hygiene for the orthodontic patient and the periodontal complications of orthodontic treatment are described. Chapter 7 covers the orthodontic management of specific periodontal problems and the periodontal effects of surgical adjuncts to orthodontic therapy are outlined in Chapter 8. The final chapter discusses aspects of relapse, the need for retention, and the soft tissue procedures that have been advocated in the prevention of relapse. This book will serve as a helpful volume for all specialists in the orthodontic and periodontal disciplines. It is also directed towards postgraduate students and practitioners with a special interest in these subjects.

Biomarkers of orthodontic tooth movement with fixed appliances and vibration device: A randomized clinical trial Marie-Claude Chouinard D.M.D. ABSTRACT Background: On average, comprehensive orthodontic treatments last approximately 21-27 months in non-extraction cases and 25-35 months when teeth elected for extraction. Longer treatment times have been associated with multiple detrimental effects such as white spot lesions, root resorption, gingival inflammation and dental caries. Recently, some evidence has shown that the application of mechanical vibration to the dentition can increase the rate of tooth movement. However, the biological mechanism underlying this effect is not clearly understood. The aims of this study were to determine if the addition of vibration to the regular fixed orthodontic appliances could alter the expression of biological factors involved in bone remodeling as well as the speed of orthodontic tooth movement and to evaluate its role in the control of pain in patients. Materials and Methods: A total of 14 patients, aged from 15 to 35 years old, in good health and exhibiting at least 5 mm of crowding were randomly allocated to two groups: one group used a vibration device 20 minutes per day in combination with fixed appliances and the other group solely had fixed appliances treatment. Biomarkers in saliva, the regularity index, the mobility of the teeth, the oral quality of life as well as the level of pain experienced during treatment were examined during the trial for an overall period of 3 months. Results: Overall, no statistically significant difference in the rate of tooth movement was found between the control and the experimental groups. Multivariate linear regression was also performed to assess any potential correlations between the initial irregularity, age, sex and type of intervention on the reduction of the irregularity index. The only significant difference appreciated among the groups was attributed to the gender at T0 and T1, with the female group experiencing statistically significant less crowding. There was no significant difference in pain levels as well as the oral quality of life of the patients at any time points between both groups. Tooth mobility at the level of the incisors significantly increased after T0, peaking at the 5 weeks’ adjustment appointment. No statistically significant difference was seen in the expression of IL-1B, IL-8 and TNF-α when control group was compared to Acceledent group. However, great variability was seen between patients. Conclusions: Application of vibration during orthodontic treatment did not show a statistically significant difference in the rate of tooth movement, the level of pain experienced by the patient as well as the oral quality of life assessment compared to the fixed appliances only group. The salivary expression of IL-1 and IL-8 also failed to show any differences between both groups at any time points.
