This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: AIM: To evaluate the accuracy of current semi-automatic and fully automatic 2D lateral cephalometric analysis programs. MATERIALS AND METHODS: 60 lateral cephalometric radiographs were randomly selected and grouped based their skeletal malocclusions to form 3 equal groups of 20 Class I, 20 Class II and 20 Class III. These radiographs were then analyzed via traditional hand-based analysis. The values obtained from this method of analysis were compared to 4 subsequent methods of analysis. These consisted of semi-automatic analysis using Dolphin Imaging software, semi-automatic analysis using Kodak Orthodontic Imaging software, fully automatic analysis using Kodak Orthodontic Imaging software and fully automatic analysis combined with limited landmark changes using Kodak Orthodontic Imaging software. RESULTS: ICC tests were completed to compare the gold standard hand-based analysis to the 4 subsequent methods. The values obtained from semi-automatic Dolphin and Kodak Orthodontic Imaging software were found to be comparable to hand-based analysis. Whereas, the values obtained from the fully automatic mode of Kodak Orthodontic Imaging software were not found to be comparable to hand-based analysis. CONCLUSIONS: Digital cephalometric programs can be used as an accurate method when performing lateral cephalometric analyses. The fully automatic mode of these programs should only be used as a support to diagnosis and not as a diagnostic tool.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its advent in 1931, analysis of lateral cephalometric radiographs has been an important aspect of orthodontic diagnosis and treatment planning. This type of orthodontic analysis provides a quantitative evaluation of the positions of various anatomical structures of the face, including skeletal, dental, and soft tissue features. Cephalometric analysis, however, is a time-consuming process and is not always performed in clinical practice. Cephalometric analysis from Cone-Beam Computed Tomography (CBCT) imaging is particularly cumbersome, requiring both reconstruction of a two-dimensional lateral cephalogram as well as subsequent computer-assisted tracing analysis using a program such as Dolphin. As the use of CBCT continues to become more prominent in orthodontics, methodologies to expedite cephalometric analysis may be valuable in facilitating their use by clinicians. Several different commercially available (e.g. CephX) and proprietary products have been created to analyze cephalometric radiographs using automated artificial intelligence (AI), but the accuracy of these products remains incompletely established. Our study examined the accuracy and workflow impacts of CephX's ABO analysis directly from CBCT compared to manual reconstruction and tracing by human examiners on 40 CBCT volumes. We hypothesized that automatically generated cephalometric analyses from CBCT volumes would differ significantly from those generated by human examiners, and that workflow time would be statistically significantly decreased in the automated analysis. In contrast, overall workflow time was found to be significantly greater for the CephX software than for the human examiners. Furthermore, our study showed that seven of the eleven measurements in the ABO analysis differed statistically significantly from the human examiners: SNB, ANB, SN-MP, L1-NB, L1-MP, LL to E-Plane, and UL to E-Plane. Nine of the eleven measurements showed average measurement error within clinically acceptable limits, while two showed greater average error than is clinically acceptable - U1-SN and L1-MP were the least accurate measurement in our study. Bland-Altman plots were constructed showing that FMA may show a slight tendency towards greater accuracy at high values, while LL to E-Plane may display a slight tendency to underestimate more frequently at low values and overestimate more frequently at high values. Only one measurement (ANB) showed limits of agreement within the maximum allowed difference; ten out of the eleven variables exceeded the maximum allowed difference. Overall, CephX may offer clinically acceptable performance for most variables in the ABO analysis, but needs further improvement overall, particularly with the inclination of the upper and lower incisors (U1-SN and L1-MP).

Download or read book The Surgery First Orthognathic Approach written by Jong-Woo Choi and published by Springer Nature. This book was released on 2021-01-20 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive guide to the surgery-first orthognathic approach for patients with malocclusion and skeletal disharmony, which has been successfully applied by the authors in their practices over the past 15 years. The approach breaks with the time-tested principles of traditional orthognathic surgery in that corrective bone surgery is performed first, without the removal of dental compensations, followed by orthodontic finishing. All aspects are covered with the aid of numerous illustrations, the aim being to provide surgeons with a systematic educational tool that will enable them to introduce the approach into their own practice. In addition, the book addresses one of the hot issues in orthodontics, occlusal plane-altering orthognathic surgery, in which surgical modification of the occlusal plane is employed to treat various types of dentofacial deformity and improve facial proportions. This promises to become a very powerful tool in modern orthognathic surgery.

Download or read book Early age Orthodontic Treatment written by Aliakbar Bahreman and published by Quintessence Publishing (IL). This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents readers with the information necessary to understand the morphogenesis of orthodontic problems, to differentiate among various conditions, and to apply early intervention approaches to optimal effect. Through integration of basic science and clinical practice, detailed case reports, and abundant illustrations, the author: * Provides an overview of dental development, from tooth formation to permanent occlusion. * Emphasizes the developmental stages that must be recognized during patient examination to facilitate differential diagnosis. * Presents clear, step-by-step instructions for different treatment options. * Demonstrates the benefits achieved by intervention in developing malocclusions and guidance of eruption. The discussions in part 1 of the concept of early-age treatment and the basic foundation of occlusal development empower practitioners to detect anomalies and intervene as necessary. Part 2 consists of chapters explaining the ontogeny, diagnosis, and early detection of, as well as the proper intervention for, nonskeletal problems. Part 3 includes chapters on early intervention for dentoskeletal problems in the sagittal, transverse, and vertical dimensions. This book cuts through the controversy surrounding early versus late treatment and shows that clinicians must decide on a case-by-case basis when to provide orthodontic treatment.

Download or read book Esthetic Oral Rehabilitation with Veneers written by Richard D. Trushkowsky and published by Springer Nature. This book was released on 2020-04-16 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book acquaints the clinician with the full range of parameters that need to be considered before undertaking an esthetic rehabilitation with veneers and describes current clinical concepts and techniques. The initial chapters provide the foundation for a comprehensive treatment plan. It is explained how digital smile design in conjunction with a wax-up and functional esthetic prototype allow a patient to visualize the possibilities. Occlusion prior to the initiation of treatment and following treatment is key to the longevity of restorations, and this aspect is given careful consideration. Detailed advice is also offered on proper selection of materials and their placement. The guidance provided will ensure that the reader is fully equipped to gather and assess all relevant information prior to commencement of the final treatment. The treatment itself can range from minimally invasive to more complex depending on the requirements of each individual case. Among the clinical concepts discussed in the book are the use of etched porcelain restorations, minimally invasive CAD/CAM veneers, and the ink glue technique.
