Available in PDF, EPUB and Kindle. Book excerpt: Objectives: The increased use of 3-dimensional (3D) cone-beam computed tomography (CBCT) in orthodontic and orthognathic cases has provided a clear understanding of its benefits compared to 2-dimensional (2D) cephalometric radiographs. However, current "3D hard tissue analyses" continue to rely on 2D linear and angular measurements and do not take advantage of the vast amount of information that can be derived from CBCTs. The long-term objective is to establish a user-friendly true 3D skeletal and dental analysis including quantifiable subnorms with respect to age, gender, and ethnicity. In order to eventually create a comprehensive and effective 3D analysis, it is necessary to first develop a true 3D description of the craniofacial structure that is both accurate and practical for the user. The specific objective of this study is to develop an approach for automatic point acquisition for 3D hard tissue analysis. Materials and Methods: The skeletal boundaries of the maxilla/palate, cranial base/zygoma, and mandible of 24 patient samples were manually plotted in a previous study conducted at UCLA. The same strict inclusion and exclusion criteria was used in both studies, including requirements for patients to be 18+ years old, have a class I skeletal relationship, and mesocephalic pattern and omitting patients with significant craniofacial defects, gross skeletal asymmetry or deformity, or history of orthognathic surgery. An extended form to the Active Shape Model (ASM) was further extended to function in 3D. Using ASM, automatic point acquisition along the boundaries of the maxilla/palate, cranial base/zygoma, and mandible was trained and implemented. A general Procrustes alignment was performed and elliptical-fourier descriptors were computed on both the points automatically plotted ("estimated landmarks") and points manually plotted ("ground-truth landmarks"), which were later compared. Results: An approach for automatic point acquisition on normative 3D CBCT images of the adult craniofacial complex was created. Conclusion: The development of an approach for automatic point acquisition on 3D CBCT images is an essential step towards establishing a true 3D skeletal and dental analysis. While this approach improves practicality by eliminating the need for a user to plot a great number of points thereby eliminating several hours of the user's time, further development of this method is needed to improve its accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review of the state of the art in Ultrasonography (USG) dentomaxillofacial imaging to help radiologists and dentists in their training and daily practice. The book examines the relationship between clinical features, diagnosis, and choice of minimally invasive technique for a range of dentomaxillofacial disorders and provides information on post-treatment therapy. Accurate interpretation of indications for treatment is the cornerstone of success in medicine, and as such, the book explains how the selection of imaging technique is closely linked to clinical and diagnostic aspects and how recognition of this relationship forms the foundation for optimal outcomes. In addition to examining the various modalities, the book highlights the role of the latest USG imaging techniques. Further, it discusses in detail the pathology, treatment, and prognosis of common and rare diseases, as well as congenital/developmental malformations in the dentomaxillofacial, an area that is often underestimated and largely ignored by dentists. Featuring updated high-resolution images created with state-of-the-art equipment, the book introduces readers to current imaging modalities. It also includes pathological descriptions of radiologic diagnoses to help clarify the pathophysiology of the disease, while the pearls and pitfalls of image interpretation provide a quick reference guide for practitioners. Written by leading international experts, this outstanding book is a valuable resource for both radiologists, dentists and students seeking a more in-depth appreciation of the subject and its contribution to the scientific radiology community.

Book Synopsis Cone Beam Computed Tomography in Orthodontics by : Sunil D. Kapila
Download or read book Cone Beam Computed Tomography in Orthodontics written by Sunil D. Kapila and published by John Wiley & Sons. This book was released on 2014-08-29 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction to dentistry, cone beam computed tomography (CBCT) has undergone a rapid evolution and considerable integration into orthodontics. However, despite the increasing popularity of CBCT and progress in applying it to clinical orthodontics, the profession has lacked a cohesive, comprehensive and objective reference that provides clinicians with the background needed to utilize this technology optimally for treating their patients. Cone Beam Computed Tomography in Orthodontics provides timely, impartial, and state-of-the-art information on the indications and protocols for CBCT imaging in orthodontics, clinical insights gained from these images, and innovations driven by these insights. As such, it is the most current and authoritative textbook on CBCT in orthodontics. Cone Beam Computed Tomography in Orthodontics is organized to progress sequentially through specific topics so as to build the knowledgebase logically in this important and rapidly evolving field. Part I provides the foundational information on CBCT technology, including radiation exposure and risks, and future evolutions in computed tomography. Part II presents the Principles and Protocols for CBCT Imaging in Orthodontics, focusing on developing evidence-based criteria for CBCT imaging, the medico-legal implications of CBCT to the professional and the protocols and integration of this technology in orthodontic practice. Part III provides critical information on CBCT-based Diagnosis and Treatment Planning that includes how to interpret CBCT scans, identify incidental pathologies and the possible other uses of this technology. Part IV covers practical aspects of CBCT’s Clinical Applications and Treatment Outcomes that encompasses a range of topics, including root morphology and position, treatment of impacted teeth, virtual surgical treatment planning and outcomes, and more.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Objectives This study evaluated the accuracy of deep neural patchworks (DNPs), a deep learning-based segmentation framework, for automated identification of 60 cephalometric landmarks (bone-, soft tissue- and tooth-landmarks) on CT scans. The aim was to determine whether DNP could be used for routine three-dimensional cephalometric analysis in diagnostics and treatment planning in orthognathic surgery and orthodontics. Methods: Full skull CT scans of 30 adult patients (18 female, 12 male, mean age 35.6 years) were randomly divided into a training and test data set (each n = 15). Clinician A annotated 60 landmarks in all 30 CT scans. Clinician B annotated 60 landmarks in the test data set only. The DNP was trained using spherical segmentations of the adjacent tissue for each landmark. Automated landmark predictions in the separate test data set were created by calculating the center of mass of the predictions. The accuracy of the method was evaluated by comparing these annotations to the manual annotations. Results: The DNP was successfully trained to identify all 60 landmarks. The mean error of our method was 1.94 mm (SD 1.45 mm) compared to a mean error of 1.32 mm (SD 1.08 mm) for manual annotations. The minimum error was found for landmarks ANS 1.11 mm, SN 1.2 mm, and CP_R 1.25 mm. Conclusion: The DNP-algorithm was able to accurately identify cephalometric landmarks with mean errors
