Book Description
The purpose of this study was to evaluate a cohort of patients who had early treatment with a facemask to determine initial outcomes of the treatment, evaluate post-treatment relapse, assess the long term need for subsequent treatment, and identify patient characteristics that may be indicative of future treatment need. Patients treated with a facemask were identified at the University of Washington School of Dentistry Graduate orthodontics clinic and two Seattle-based private orthodontic practices. Treated patients were frequency matched to historic untreated controls. Cephalometric changes between different time points were compared among the two groups to determine which changes can be attributed to growth versus treatment. For the treated group, the need for orthognathic surgery was assessed by three orthodontists, independently. Based on their recommendations, a logistic regression model was developed to identify variables associated with surgical need both when the patient is in the permanent dentition and prior to initiation of facemask therapy. The following significant mean changes were seen over the course of facemask therapy in the treated group: SNA increased by 0.9°, ANB increased by 1.0°, mandibular plane increased by 1.0°, overjet increased by 3.3 mm, IMPA decreased by 1.9°, interincisal angle decreased by 4.0°, and U1-NA increased by 3.7°. The change in SNB, Wits Appraisal, and LFH were not statistically significant. Over an average of 3.1 years following interceptive treatment, there was a statistically significant decrease in overjet by 1.2 mm, ANB by 1.4° and an increase in SNB by 2.1°. All other values did not show significant change. Even after early treatment with a facemask therapy, orthognathic surgery as the ideal subsequent treatment was recommended for 41% of patients. Decreased overjet, proclination of the maxillary incisors, retroclination of the lower incisors, and increased lower facial height were associated with surgical recommendations. The lower incisor position prior to interceptive treatment is also associated with the future need for surgery. Although there was significant skeletal change over the course of interceptive treatment, similar change was also seen in untreated controls. Thus, the positive change in overjet as a result of facemask therapy is attributed more to dental change than skeletal. The skeletal change we see during the interceptive treatment is most likely due to growth and not facemask therapy. Following treatment, the decrease in overjet can be attributed to continued mandibular growth. The position of the maxillary and mandibular incisors are important characteristics to take into consideration when determining the probability of facemask therapy preventing the future need for orthognathic surgery.

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."

Book Description
This book describes the scientific evidence for a newly developed ACTIVE SKELETONIZED SUTURAL DISTRACTOR APPLIANCE (ASSD). ASSD appliance where used successfully in a randomized clinical trial that proof its power to correct sever skeletal class III malocclusion. ASSD appliance can be consider a paradigm shift in the treatment of class III malocclusion as it can replace conventional surgical distractor. ASSD can provide adolescent Class III patients with a rapid and comfortable treatment option. It is hoped that this clinically effective, noninvasive and inexpensive treatment will have a significant improvement in the quality of life of those type of patients.

Book Description
Provides the latest information on all aspects of using temporary anchorage devices in clinical orthodontics, from diagnosis and treatment planning to appliances and applications Written by some of the world’s leading experts in orthodontics, Temporary Anchorage Devices in Clinical Orthodontics is a comprehensive, up-to-date reference that covers all aspects of temporary anchorage device (TAD) use in contemporary orthodontics. Taking a real-world approach to the subject, it covers topics ranging from diagnosis and treatment planning to the many applications and management of complications. Case studies demonstrate the concepts, and high-quality clinical photographs support the text throughout. The book begins with an overview of clinical applications and fundamental principles of TADs. It then goes on to cover biomechanical considerations for controlling target tooth movement with TADs. Biomechanical simulations for various clinical scenarios treated with TADs are addressed next, followed by an examination of histological aspects during the healing process and anatomical considerations with TADs.

Book Description
This book uses real-world clinical case analyses of hot topics to provide insights into noninvasive mechanical ventilation (NIV). Written by leading international teachers and experts, it features a selection of “major controversial topics in clinical practice” and demonstrates how these cases can be used to teach about NIV. It then presents a discussion of the topics in various scenarios (anesthesiology, critical care, emergency, pneumology and sleep medicine, as well). The chapters allow readers to develop a case-by-case understanding of NIV in acute and chronic respiratory disorders, and perioperative and in intensive care patients, also thanks to Electronic Supplementary Materials. Lastly the authors summarize five key points / recommendations. This book is an attractive resource also for universities / educational seminars / national and international postgraduate courses and hot-topics sessions at national/international congresses.
