Book Description
Objective: The purpose of this study was to evaluate the maxillary central incisor position changes after orthodontic treatment in Class I, II and III malocclusions. Material and Methods: This retrospective cohort study evaluated nighty non extraction orthodontic Class I, II and III cases which were collected randomly from the Orthodontic clinic at the University of Alabama at Birmingham and the Institutional Review Board of the University of Alabama at Birmingham approved the study. All the chosen cases were treated with fixed appliances and according to the standards of American Board of Orthodontics. All the lateral cephalo-metric radiographs were taken using the Orthopantomograph OP100, Instrumentarium Corp.Imaging Division machine(Finland) and traced digitally using the Dolphin Management and Imaging Software, Version05.05.5070.221436(US &Canada). In order to evaluate the maxillary incisor position changes ,the U1-PP(°), U1-SNo, U1-NAo, U1-NA(mm), U1 perpendicular to FH mm(U1-FH) and U1-Oc° cephalometric measurements were carried out based on the post-treatment lateral cephalometric measurements. In order to determine if there is a statistically significant difference in Maxillary central incisor positions among class I, II and III malocclusions , equivalence tests for post-treatment cephalometric measurements were performed using a range of ± 2 either degrees or millimeters Results: The maxillary incisors position does show a significant difference from the normal value among the Class I, II and III. Class III malocclusion presented a greater proclination of maxillary incisor teeth compared to Class I and Class II malocclusions. Class I has a tendency to be more positive of the normal and Class II to be more negative than the normal. The maxillary incisors changes, seem to not fall within the range of ±2 mm according with the equivalent tests for post-treatment cephalometric measurements compared to the respective normal value. The final position of the maxillary incisors after orthodontic treatment depends mainly on the initial position of these teeth and the discrepancy of jaws. Conclusion: There is a significant difference in the positioning of the maxillary incisors among the class I, II and III malocclusions. The post-treatment measurements such as U1-FHmm, U1-NA mm and U1-SN° and U1-NA° present a significance difference among Class I, II and III malocclusions. In In the class II, the maxillary teeth showed to be more upright than Class I and III malocclusions after orthodontic treatment. The U1-PP° showed no significant difference among the malocclusions. In this study, the U1-PP° was the same for r the Class I and III.

Book Description
From an award-winning author, this concise and visual guide describes the two-phase treatment approach to the orthodontic management of children with uncrowded Class II division one malocclusion. In this widely accepted treatment method, a bionator (Andresen) appliance is used in phase one, followed in phase two by high quality preadjusted fixed appliances. Properly managed, and with correct case selection and timing, this system of treatment produces high-quality results, and can be the easiest route to a successful outcome in many patients. A new book by one of the most successful orthodontics authors in the world which offers a concise and easily assimilated account of the treatment of an important group of orthodontic patients. Describes the two phase treatment approach a functional appliance in phase one, and the latest and best in bracket and wire technology in phase two. This produces consistently high-quality results and is the easiest route to an ideal outcome in many patients. Stage by stage case histories enhance the readers understanding of the system. Lavishly illustrated with top-quality colour photographs and line diagrams. Has a focus on methods of optimising patient cooperation, a topic which is often overlooked. Discusses difficult situations where growth or cooperation levels are below expectations.

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.
