Book Description
Open-Bite Malocclusion: Treatment and Stability presents the etiology, treatment, and its stability of anterior open bite malocclusion in the early, mixed, and permanent dentitions. Special emphasis is devoted to orthodontic treatment and its stability in the permanent dentition because this is the time when treatment of open bite presents greater relapse. Appropriate for clinicians, orthodontic residents, and dental students, Open-Bite Malocclusion covers the most simple treatment approaches to the most complex, from orthodontic devices to tooth extraction to surgery. Unique to this book is the discussion of post-treatment stability. Drs. Janson and Valarelli highlight the post-treatment changes and presents strategies to increase treatment stability. This allows the clinician to be able to predict the stability probabilities when treating anterior open bite malocclusions in the permanent dentition either with or without extraction, orthodontic-surgical therapy, or with occlusal adjustment.

Book Description
Evidence-Based Orthodontics satisfies the educational demands of orthodontics, which demands the integration of the best research evidence with the clinician’s expertise and the patient’s unique values and circumstances. This land-mark text is the first to be devoted to the methodology, principles and practice of evidence-based practice in orthodontics. It aims to serve as a reference for those wishing to understand the principles of evidence-based practice including the foundation for clinical study design, epidemiology and the statistical inferences from data. The ability to define a search strategy from established databases and to identify relevant clinical and translational research in the scientific published literature requires a new approach in orthodontic education. Evidence-Based Orthodontics provides a contemporary approach to those strategies in clinical orthodontic practice. The growing ability to translate critical appraisals of evidence into clinical practice and evaluate clinical evidence for its validity and potential usefulness requires an understanding of basic elements in epidemiology and biostatistics. Evidence-Based Orthodontics provides its readers with a cogent, clear resource with which to navigate and understand this important subject area. It provides students and practitioners of orthodontics with an indispensible guide to this vital tenet of education, research, and clinical practice.

Book Description
This handbook provides a short, contemporary text on the management of dentofacial deformities. The importance of a well organised, inter-disciplinary approach is emphasised throughout and the following key areas are presented: A detailed account of the role of the psychologist, from initial assessment through to post-operative support. A systematic approach to dentofacial assessment, including a section on diagnostic records and an overview of cephalometry. A logical step-by-step approach to treatment planning, emphasising the interactive thought process required when setting orthodontic and surgical objectives. The fundamentals of surgical orthodontics, with the scope and limitations of orthodontic appliances clearly explained for each phase of treatment. A description of orthognathic technical procedures and how potential errors can be minimised in order to improve the accuracy of model surgery. An account of how to carry out photo-cephalometric profile prediction planning, including a critique of the method. A detailed description of the full range of mandibular and maxillary orthognathic surgical procedures, including indications and complications. A chapter on higher-level osteotomies for the treatment of more severe craniofacial abnormalities is included for completeness. A series of six contrasting case studies. There is an emphasis on the technological advances that are rapidly enabling the global paradigm shift from 2D to 3D planning.

Book Description
This study aimed to examine end-of-treatment outcomes of severe Class II Division I malocclusion patients treated with surgical or non-surgical approaches. This study tests the hypotheses that occlusal outcomes (ABO-OGS) at end of treatment will be similar while cephalometric outcomes will differ between these groups. A total of 60 patients were included: 20 of which underwent surgical correction and 40 of which did not. The end of treatment ABO-OGS and cephalometric outcomes were compared by Mann-Whitney U tests and multivariable linear regression models. Following adjustment for multiple confounders (age, gender, complexity of case, and skeletal patterns), the final deband score (ABO-OGS) was similar for both groups (23.8 for surgical group versus 22.5 for non-surgical group). Those treated surgically had a significantly larger reduction in ANB angle, 3.4 degrees reduction versus 1.5 degrees reduction in the non-surgical group (p=0.002). The surgical group also showed increased maxillary incisor proclination (p=0.001) compared to candidates treated non-surgically. This might be attributed to retroclination of incisors during treatment selection in the non-surgical group - namely, extraction of premolars to mask the discrepancy. Studies such as this are necessary because they begin to give practitioners view of not only the outcomes of a single treatment plan, but a comprehensive approach by providing evidence of the over-arching treatment used for successful treatment in both groups.

Book Description
Class II malocclusions can be treated with a combination of orthodontics and orthognathic surgery. The severity of the malocclusion and growth potential play an important role in the treatment decision. Treatment involving orthognathic surgery is usually recommended after active growth is over to minimize relapse. On the other hand, improvement of a severe skeletal deformity and associated esthetic imbalance during adolescence can increase the patient’s quality of life and, in some cases, early treatment may decrease the financial burden due to changes in insurance coverage. Also, surgery and recovery from surgery may be easier and with less complications in younger individuals. The purpose of this study is to evaluate the effect of timing on treatment outcomes and the surgical complications of orthognathic surgery between younger and older Class II malocclusion patients. Methods Records of local orthodontists and oral surgeons were screened for inclusion in the study: Class II malocclusion treated with a combination of orthodontics and orthognathic surgery of the mandible (with or without maxillary surgery). Syndromic patients were excluded. Lateral cephalograms (initial, pre-surgical, post-surgical and final) as well as surgical notes were obtained. Patients were divided in 3 groups based on chronological age: 13-19, 20-25, 33-40. Dolphin imaging software was used and landmarks identified for cephalometric analysis. Cephalometric measurements were used to analyze the dental and skeletal changes associated with surgical and orthodontic treatment. Immediate and post-surgical complications were evaluated. A total of 112 patients were identified who fit the inclusion criteria. Only 35 patients had available cephalometric data (T1 pre-orthodontics; T2 pre-surgical; T3 postsurgical and T4 post treatment) which were used to compare anteroposterior (A-P) changes between the adolescent and adult patients. Less changes in cephalometric measurements were observed between T1-T2 and T3-T4 in the younger patients. Surgical data for 104 patients were included in the study, 8 patients were excluded due to missing data. For 1-jaw surgery, blood loss in the older group was greater than in the younger group. Limited TMJ opening (24-31 mm) at 6 weeks and more post- surgical complications after 1 jaw surgery were observed in the older group. More post-surgical complications after 2 jaw surgery (condylar resorption, infection, residual sensory loss and TMJ pain) were observed in the younger patient group. Younger patients who underwent orthognathic surgery to correct a Class II malocclusion had similar orthodontic treatment outcomes and similar immediate surgical complications compared to older patients. Possible continued mandibular growth contributed to improved skeletal relationships after the orthognathic surgery in the younger patients. Overall, there was no statistical or clinical difference in A-P changes of mandibular advancement surgery, nor differences in surgical complications between young and older patients.
