Book Description
Orthodontics is a sub-specialty of dentistry that deals with the treatment of misaligned teeth. This book describes the history and evolution of orthodontics. Beginning with an introduction to the history of dentistry in general, the following chapters look at the history of orthodontics in different parts of the world, including the USA, UK and parts of Europe. The following sections describe the evolution of key aspects within orthodontics including cephalometrics, removable and fixed appliances and cleft palate. Separate chapters are dedicated to the contributions of eminent inventors in the field. The development of more recent advances in orthodontics such as invisalign and dental lasers is also covered. This book includes more than 180 photographs, tables and illustrations, as well as extensive references for further reading.

Book Description
Abstract: Introduction: The object of this research was to evaluate the reliability and validity of Peer Assessment Rating (PAR) index scores derived from computerized digital models. Computer based digital orthodontic models have been shown to be valid and reliable when making measurements of tooth size and simple diagnoses of dental malocclusions. The validity and reliability of PAR scores from digital models and plaster models that have been previously scored and standardized for a calibration exercise for the PAR index have not been established. Methods: Ten examiners were trained to score digital and plaster models using the PAR index. Thirty standardized and previously scored plaster PAR models used in PAR calibration were digitized using digital study model technology. The plaster and digital calibration models were randomized and scored by the ten examiners. All measurements were repeated by all examiners at a second session. Results: Plaster and digital scores were compared to the gold standard PAR scores for validity. The Intraclass Correlation Coefficients (ICC) for plaster models ranged from 0.808-0.926. The mean ICC for plaster models was 0.891 with a 95% confidence interval (CI) of 0.829-0.940. The ICCs for digital models ranged from 0.846-0.922. The mean ICC for digital models was 0.878 with CI of 0.811-0.931. Intra-rater reliability was excellent for plaster (ICC =0.919) and for digital models (ICC= 0.905). Inter-rater reliability was also good for plaster (ICC=0.912) and digital models (ICC=0.883). Conclusions: The PAR index scores obtained from the digital and plaster calibration models were shown to be valid and reliable.

Book Description
This is a research-based book on the clinical use of the Herbst appliance in the management of Class 2 malocclusions. Different clinical problems and questions are addressed in the light of the corresponding research existing. Thus, in contrast to other Class 2 alternative treatments, the Herbst appliance approach is based on scientific research.

Book Description
The purpose of this study was to investigate the degree of agreement between deviations from cephalometric norms and clinicians' subjective assessments of treatment difficulty and success. Six orthodontists subjectively assessed and ranked complete pre- and post-treatment records of 36 orthodontic patients for difficulty of treatment and favorability of treatment outcome. Twenty-five hard tissue and 20 soft tissue cephalometric landmarks were located and digitized by two orthodontic residents for all pre- and post- treatment headfilms. Each patient's pre- and post- treatment deviations from 7 commonly used cephalometric hard and soft tissue norm sets were determined. The subjective assessments were compared to the deviations from the published and sample's norms. There were no significant correlations between subjective assessments of difficulty or favorability of treatment and degree of deviations from hard tissue cephalometric norms. Significant negative correlations were found between subjective assessments of favorability of treatment and degree of deviations from specific soft tissue cephalometric norms (E-line and H-Line). This data suggests that clinicians' decisions regarding treatment difficulty or treatment success rely more heavily on factors other than coincidence with hard tissue cephalometric norms.

Book Description
"Orthodontic Treatment of Class III Malocclusion is a clinical textbook which highlights both research findings as well as clinical treatment of patients with Class III malocclusions. The volume equips readers with a critical review of present information about 1) the craniofacial biology behind various treatment strategies, 2) Diagnosis and treatment planning in both growing and non-growing Class III patients and 3) Contemporary orthodontic appliances using implants and miniscrews. The book is divided into sections proving evidence-based research on the following aspects of Class III malocclusions: the genetic and epigenetic factors contemporary diagnosis and treatment planning for patients early treatment of Class III problems treatment of Class III problems in the adolescents surgical treatment of adult Class III patients treatment of Class III problems in patients with craniofacial anomalies Orthodontic Treatment of Class III Malocclusion will empower clinicians with a sound knowledge about rationale for using certain treatment modalities and will help both general practitioners and specialists such as pediatric dentists and orthodontists to use this information for their daily practice."
