Book excerpt: Cleft lip with or without cleft palate (CL/P) is one of the most common craniofacial anomalies. Patients with CL/P often require extensive and prolonged orthodontic treatment due the skeletal and dental malocclusions that frequently manifest, making the orthodontic burden of care significant compared to the non-cleft patient. Orthodontic treatment may be required at various stages in their dental and skeletal development, during which orthodontic records must regularly be taken, including cephalometric radiographs. These radiographs allow for analysis of skeletal and dental relationships by relating various anatomical landmarks through linear and angular measurements. Due to the time-consuming nature of the current computer-aided method, which currently involves an orthodontist locating points of a lateral skull radiograph on a computer monitor, systems have recently been developed to automate the cephalometric process. However, while systems such as CephX have been shown to significantly shorten analyzing time, the accuracy of the measurements is inadequate. Further, radiographs of CL/P-affected patients are often excluded from the sample, as identification of cephalometric landmarks is more complicated due to abnormal anatomy. There is promise that lateral simulated 2D cephalometric projections from CBCTs improve the accuracy of cephalometric measurements over 2D cephalograms. This study sought to compare the accuracy and analyzing time between web-based fully automated and computer-aided cephalometric analysis of lateral cephalometric images derived from cone-beam computed tomography in unilateral cleft lip and palate-affected patients. Both methods of cephalometric analysis were performed on 36 CBCTs obtained of individuals with unilateral cleft lip and palate in the mixed dentition stage. Of the 12 measurements obtained, 4 measurements, U1-PP (°), SN-MP (°), U1-SN (°) and U1-NA (mm) were both statistically significant (P

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).

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive reference work for managing patients with orofacial clefts and complex craniofacial conditions from birth to skeletal maturity Cleft and Craniofacial Orthodontics is a comprehensive and detailed reference work on the management of patients with orofacial clefts and complex craniofacial conditions. Covering patients ranging from birth to skeletal maturity, the book provides orthodontists, plastic and oral and maxillofacial surgeons, speech and language therapist, pediatric dentists, and prosthodontists with the information they need to evaluate and treat these conditions. Highlighting the multidisciplinary team approach, the book aids clinicians in developing a complete plan for their patients. Each chapter is organized to reflect clinical practice, making it easy to apply the information to the treatment setting. Additionally, a companion website offers video clips of surgical and orthodontic procedures to further aid in reader comprehension and application. Sample topics covered within the work include: Introduction to orofacial clefting: cleft lip and palate anatomy, cleft types and classification, epidemiology, and genetics of cleft lip and palate Early management of orofacial clefting: prenatal diagnosis and counselling, feeding infants with clefts, and development of nasoalveolar molding therapy Orthodontic treatment: interceptive orthodontics, management of anteroposterior and transverse discrepancies, preparation for alveolar bone grafting, and combined orthodontic-orthognathic management. Orthodontic and multidisciplinary management of twenty complex craniofacial conditions including craniofacial microsomia, Treacher-Collins syndrome, and syndromic craniosynostosis Orthodontists, plastic surgeons, craniofacial surgeons, oral and maxillofacial surgeons, speech and language therapist, pediatric dentists, prosthodontists, and otolaryngologists can use this book to attain essential knowledge on managing patients with orofacial clefts and complex craniofacial conditions and understand how to apply that knowledge to practical patient settings.

This book was released on 2013 with total page 238 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.
