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
Treatment of young Class III patients with maxillary deficiency is generally directed towards achieving positive overjet through a combination of dentoalveolar and skeletal effects. Reverse pull headgear has been used for the protraction of the deficient maxilla in young class III patients, it does not have a positive feedback esthetically and can be an obstruction in daily routine. The short term outcomes of maxillary protraction treatment have been documented limited orthopedic effect on the maxilla, rotation of the mandible and dentoalveolar changes. The long term follow ups of maxillary protraction indicated a 25% to 33% chance of relapse. A significant proportion of patients with maxillary deficient Class III skeletal malocclusion ultimately require orthognathic surgery, any treatment approach that could eliminate the need for, or reduce the extent of, future surgery would be of great benefit to these patients.

Book Description
This case-based clinical text is an exhaustive review of orthodontic problems in the vertical dimension and evidence-based guidelines for successful diagnosis and treatment. A total of 21 cases address dental deep bites, skeletal deep bites, dental open bites, skeletal open bites, and posterior open bites. Each case includes pre-treatment, interim, and post-treatment orthodontic records, as well as references to provide a solid evidence base for decision making. Written with a clinical focus, Orthodontics in the Vertical Dimension is ideal for the practicing orthodontist and makes an excellent resource for residents in pursuit of board certification.

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. Other chapters cover: Class II Correction with TADs, Distalization with TADs, TAD-anchored Maxillary Protraction, Maxillary Expansion with TADs, Anterior Open Bite Correction with TADs, TAD-assisted Aligner Therapy, TADs vs. Orthognathic Surgery; Legal Considerations When Using TADs; and much more. Provides evidence-based information on the use of TADs, with a focus on improving outcomes for patients Considers topics ranging from diagnosis and treatment planning to specific clinical applications and appliances Takes a real-world clinical approach, with case studies demonstrating concepts Written by international experts in the field Presents hundreds of high-quality clinical photographs to support the text Temporary Anchorage Devices in Clinical Orthodontics is an essential resource for orthodontists and orthodontic residents.

Book Description
Objectives: The purpose of this study was to use Finite Element Method (FEM) to simulate various clinical protocols for maxillary protraction with micro-implants, which can provide skeletal changes without the use of surgery. We aim to analyze how location and direction force alters the skeletal effect. Analysis of the skeletal effects can be used to improve clinical protocols for treating class III patients. Methods: A 3-dimensional cranial mesh model with associated maxillary sutures was developed from CT images and Mimics modeling software. Utilizing ANSYS simulation software, protraction forces were applied at different locations and directions to simulate conventional facemask therapy; seven different maxillary protraction protocols utilizing micro-implants. Stress distribution and displacement were analyzed. Video animations and superimpositions were created to illustrate the skeletal effect from varying location and direction of force application. Results: Conventional facemask and facemask from anterior micro-implants at 15° below and 30° above the occlusal plane result in counter-clockwise rotation of the maxillary complex. In contrast, maxillary protraction at 45° below the occlusal plane with anterior or posterior micro-implants displayed clockwise rotation of the maxilla. At 30° below the occlusal plane, Facemask with palatal or anterior micro-implants translated the maxilla downward and forward, while protraction from posterior micro-implants closely resembled pure anterior protraction of the maxilla. Facemask without micro-implants resulted in higher internal stresses, suggesting force dissipation to bone rather than to the sutures. Conclusion: Location of micro-implant placement and direction of pull altered the skeletal response, changing the upward or downward displacement of the maxillary complex, maxillary incisor upward or downward movement, and amount of protraction. Brachyfacial class III patients with a deep bite would benefit from counter-clockwise rotation of the maxilla, resulting in bite opening. Dolicofacial patients with open bite tendency require protraction that minimizes maxillary downward movement. As a result, class III growth modification treatment with micro-implants can be customized for each patient to maximize clinical effectiveness.
