An illustrated guide for the complex process of orthodontic diagnostics and indication. The total process of treatment planning including the scientific bases is pictorially described. Beside the conventional methods of examination and model analysis, emphasis is placed on the cranio-facial growth processes, the aetiology of malocclusions and on the importance of functional analysis. The following three aspects are described in detail in this book: Growth of the Facial Skeleton - types of treatment which promote or guide growth. In order to control these natural processes artificially, a precise understanding of them is required. Aetiology of the Malocclusion - the various types of causative therapy and the elimination of the causes. Functional Analysis - many malocclusions are a result of dysfunctions. As a variety of methods are available for treating dysfunctions, functional analysis is taken very seriously.

Authored by the foremost experts in the field, this compact reference serves the student and clinician by relating basic science to successful treatment planning. It demonstrates how the best instrument in dental medicine is often the practitioner's knowledge of the body's biologic growth principles. Donald H. Enlow, MS, PhD, the acknowledged pioneer and research leader in facial growth study for the past twenty years, provides comprehensive insights into normal and abnormal craniofacial growth and development. His colleague, Mark G. Hans, DDS, MSD, contributes a concrete understanding of the importance of these concepts in clinical practice. It delves into the interrelationships between soft tissue and skeletal growth, and examines the impact of function upon development. And it stresses the ways in which these biological principles and concepts affect treatment planning, selection, results, relapse, tooth movement, and nonbiological prosthetic implants during growth. Detailed illustrations make key concepts and developmental processes simple to grasp, and a user-friendly organization allows for quick comprehension and convenient referral.

Objective: The objective of this study was to determine if a difference existed between arch forms created from tooth surfaces, alveolar bone, and overlying soft tissue. Materials and Methods: The sampling population for this study was 18 individuals with a Class I malocclusion, mild crowding, and a CBCT image of good diagnostic quality. The Facial-axis point was chosen to create the arch form from teeth, the Bowman-Kau point was used to establish the arch form from the alveolar bone, and the WALA ridge was used to calculate the soft tissue arch form. A predetermined algorithm was then used to create five separate arch forms per patient. The arch forms were categorized according to shape and then superimposed on each other within an arch and the distance between tooth, bone, and tissue was calculated. Results: For all characteristics of the tooth, bone, and tissue, the calculated distances were significantly different from 0. The distances between tooth and bone were larger for the mandible compared to maxilla (mean 3.30 vs. 2.48, respectively). The larger distances seemed to be located more posteriorly than anteriorly. The distance between tooth and tissue was largest for the second premolar (2.35±1.59), first molar (2.86±0.63), and second molar (3.25±0.87). A significant difference in distance between tooth and bone on both the maxilla and mandible was observed among race but limited to blacks vs. whites. There were no significant differences in distance between the tooth and either bone or tissue in regards to gender and age. Conclusions: The arch form shapes obtained from the teeth, alveolar bone, and soft tissue are highly individual. However, there was a significant positive correlation found between the tooth, alveolar bone, and soft tissue arch forms. The overall distance between tooth and bone was greatest for the mandible compared to maxilla. The largest difference between tooth and bone were found at the canine and second molar in the maxillary arch followed by the first molar, first premolar and then second premolar. In the mandibular arch the largest difference was found at the first and second molars followed by the canine, first premolar, and second premolar.

The size and shape of the arches have a considerable implication in orthodontic diagnosis and treatment planning, affecting the space available, dental aesthetics and stability of the dentition. There are variant types of faces which orthodontists have to treat with best possible esthetics and stability in their clinics. The arch dimensions are usually modified according to treatment plan which can ultimately also affect the arch forms. Stability of arch form is one of the most desirable goals of orthodontics. Current literature is insufficient in relating arch dimensions and arch form with other craniofacial dimensions. Hence this book evaluates the relationships of the above and compares the arch forms in various vertical face types. This book gives comprehensive information about the subject of arch dimensions and arch forms. The conclusions and the clinical applicability section will guide clinical orthodontists in establishing the orthodontic treatment goals customized to an individual patient with the best possible esthetics and stability.
