Cephalometric Measurements

The analysis of scientific literature points to significant ethnic, racial, age and sexualdifferences in cephalometric indices obtained by the method of C. J. Burstone, whichnecessitates conducting similar cephalometric studies among different age and sexgroups of the population of Ukraine with physiological bite. The purpose of the study isto establish and analyze the cephalometric parameters by the method of C. J. Burstonein boys and girls of the Podillia region of Ukraine with orthognathic bite. Primary lateralteleroentgenograms of 38 boys and 55 girls with normal occlusion close to orthognathicbite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken fromthe data bank of the research center of the National Pirogov Memorial MedicalUniversity, Vinnytsya. Cephalometric measurements were performed according to therecommendations of C. J. Burstone. The statistical processing of the obtained resultswas carried out in the licensed package "Statistica 6.0" using nonparametric methodsfor evaluating the obtained results. When comparing the cephalometric parametersused in the analysis of C. J. Burstone between boys and girls with orthognathic bite inboys, the values of the following distances are significantly higher: Ar-Pt (PosteriorSection of Cranial Base), Pt-N (Anterior Section of Cranial Base), N-ANS (AnteriorUpper Facial Height), ANS-Gn (Anterior Lower Facial Height), PNS-N (Posterior UpperFacial Height), 1l-MP (Distance of Incisal Edge of 1L to Palatal Plane), 6u-NF (Distanceof Mesial Cusp of 6u to Palatal Plane), 6l-MP (Distance of Mesial Cusp of 6l toMandibular Plane), ANS-PNS (Maxillary Length), Ar-Go (Ramus Length), Go-Pog(Mandibular Length), B-Pog (distance from point Pog to point B, parallel to mandibularplane) and A-B (Distance of A to B on Occl. Plane); and in girls - only angle OP-HP(Angle of Occl. to Horizontal Plane). More than half of the cephalometric parametersobtained in the boys and girls of Podillia with orthognathic bite have reliable or tendencydifferences with the magnitude of the parameters given by C. J. Burstone, whichconfirms the need to establish their regional standards for correct use in Ukraine.

In spite of the existence of numerous developed methods of cephalometric analysis, which should help to choose the right direction of orthodontic treatment, usually the doctor has to act intuitively, based on his experience, because their development didn’t take into account numerous factors (ethnicity, age, gender, etc.). Improving these techniques, considering the above-mentioned factors, would significantly increase their effectiveness, and hence the quality of providing dental care to the population. The purpose of the work is to construct and analyze a regression model of teleroentgenographic indicators used in the method of C. J. Burstone in young men and women with normal occlusion close to orthognathic bite and harmonic face. Primary side teleroentgenograms of 38 young men (aged 17-21 years) and 55 young women (aged 16-20 years) with normal occlusion close to orthognathic bite and harmonic face, obtained from the Veraviewepocs 3D device, Morita (Japan), taken from the bank data of research center of National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of C. J. Burstone. All indicators were divided into three groups: 1 - metric characteristics of the skull, which usually do not change during surgical and orthodontic treatment; 2 - indicators of the tooth-jaw system, the definitions of which most often need to be guided by the orthodontic treatment of growing patients and orthodontic surgery, which allows people with already formed bone skeleton to change the width, length, angles and position of the bones of the upper and lower jaws; 3 - indicators that actually characterize the position of each individual tooth relative to each other, to the bony cranial structures and face profile. Regression models of individual teleroentgenographic indicators used in the method of C. J. Burstone, built using the licensed package “Statistica 6.0”. Constructed all 6 reliable models of indicators included in the second group (anterior lower facial height ANS-Gn/Me, maxillary length ANS-PNS, ramus length Ar-Go, mandibular length Go-Pog, anterior upper facial height N-ANS and posterior upper facial height PNS-N) depending on the indicators of the first group (posterior section of cranial base Ar-Pt, anterior skull base length N-CC, angle of the cranial tilt POr-NBa, anterior section of cranial base Pt-N and distance P-PTV); as well as all 7 reliable models of indicators included in the third group (distances 1u-NF, 1l-MP, 6u-NF, 6l-MP and angles OP-HP, Max1-NF/Max1-SpP, Mand1-Mp/Mand1-MeGo) depending on the indicators of the first and second (distance A-B, A-NPog, Gо-CF, Max-Mand, N-A, N-B, N-Pog and Xi-Pm and angles MeGo-NPog, MP-HP, NAPog, N-ANS-Pog, N-CF-A, NPog-POr, POr-CFXi і POr-ANSPNS) groups. It was established that in young men the model of telerentgenographic indices included in the second group depending on the indicators of the first group and included in the third group, depending on the indicators of the first and second groups, have a higher determination coefficient than in young women (R2 from 0.806 to 0.918 in young men and from 0.510 to 0.768 for young women, and from 0.750 to 0.993 for young men and from 0.510 to 0.986 for young women). In the analysis of entering into the regression models of the relevant predictors found that in young men among the teleroentgenographic indicators of the first group included in the models of indicators of the second group most often included - distances P-PTV (33.3%), Pt-N and N-CC (by 25.0%); and in young women– distances N-CC (38.5%) and P-PTV (30.8%). It was also found that among young men among the teleroentgenographic indicators of the first and second groups that were included in the models of the third group of indicators most often included - distance ANS-Gn/Me (12.8%), the magnitude of the angles NAPog, POr-CFXi and POr-ANSPNS (by 9.4%); and in young women– distance ANS-Gn/Me (13.2%), distances А-В and PNS-N and the magnitude of the angle NAPog (by 7.9%).

According to many numerical literary sources, the modern direction of provision of dental care involves an individual approach to the patient, in particular, based on his gender, age and nationality. This calls for the creation of its own regulatory bases for the population of different countries and ethnic groups, taking into account all possible criteria. The purpose of the study is to establish and analyze the cephalometric parameters by the method of E.P. Harvold in young men and women of Podillia region of Ukraine with orthognathic bite. Primary lateral teleroentgenograms of 38 young men and 55 women with normal occlusion close to orthognathic bite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken from the data bank of the research center of the National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of E.P. Harvold. Statistical processing of the obtained results was carried out in the license package "Statistica 6.0" using nonparametric methods of estimating the results. When comparing teleroentgenographic indices between boys and girls of the Podillia region of Ukraine with orthognathic occlusion, significantly higher values of the length of the upper and lower jaw, lower facial height and interjaw differences in young men were established, and Ap1uAp1l-DOP angle was significantly higher in young women. When comparing these data with the results obtained by E.P. Harvold, the boys and girls of the Podillia region of Ukraine with orthognathic bite have significantly lower values of the length of the upper and lower jaw and lower facial height. In addition, Ukrainian young women have significantly higher values of the Ap1uAp1l-DOP angle and a tendency to lower interjaw differences, while in young men, the tendency towards higher values of the cross-sectional angle than the value of these parameters obtained by E. Harvold is established. The results of the study confirm the need to create a normative basis for teleroentgenographic indices by the method of E.P. Harvold for the population of different regions of Ukraine, taking into account both sexual and age affiliation.

OBJECTIVE: The aim of this study was to determine the standards of facial height in 30 young (14-year-old) Japanese-Brazilian descendants with normal occlusion, and assess whether sexual dimorphism is evident. METHODS: The cephalometric measurements used followed the analyses by Wylie-Johnson, Siriwat-Jarabak, Gebeck, Merrifield and Horn. RESULTS: Results showed dimorphism for total anterior facial height (TAFH), lower anterior facial height (LAFH), anterior facial height (AFH), total posterior facial height (TPFH) and upper posterior facial height (UPFH) measurements. CONCLUSIONS: The standards of facial heights in young Japanese-Brazilian descendants with normal occlusion were observed. Sexual dimorphism was identified in five out of thirteen evaluated variables at this age range.

AbstractThe aim of this study was to evaluate the craniofacial cephalometric characteristics of individuals with Down syndrome (DS), comparing them with healthy subjects. An electronic search was made in Pubmed, Embase, Lilacs, Scopus, Medline and Web of Science without imposing limitations on publication date or language. Studies were selecting following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The PECO acronym was applied as follows: P (population), individuals with DS; E, (exposition) diagnosis of DS; C (comparison), individuals without DS; O (outcomes) craniofacial characteristics based on cephalometric measurements. Independent reviewers performed data extraction and assessed the methodological quality of the articles using the Newcastle–Ottawa Quality-Assessment-scale. Seven case–control studies were included in meta-analysis. Given the variability of the cephalometric measurements used, only those that had been reported in at least three or more works could be included. Anterior cranial base length (SN), posterior cranial base length (SBa), total cranial base length (BaN), effective length of the maxilla (CoA), sagittal relationship between subspinale and supramentale (ANB), anterior facial height (NMe), and posterior facial height (SGo) values were significantly lower in the DS population than among control subjects. No significant differences were found in sagittal position of subspinale relative to cranial base (SNA) and sagittal position of supramentale relative to cranial base (SNB). Summarizing, individuals with DS present a shorter and flatter cranial base than the general population, an upper jaw of reduced sagittal dimension, as well as a tendency toward prognatic profile, with the medium third of the face flattened and a reduced anterior and posterior facial heights.

Research of computed-tomographic size of teeth in representatives with differenttypes of faces and physiological occlusion allows dentists to make the correct approach toorthodontic treatment of patients in the clinic of orthodontics, orthopedic dentistry andmaxillofacial surgery. The purpose of the work is to establish the limits of the percentilescope and the peculiarities of the computed-tomographic vestibular-tongue sizes of teethin young boys and girls with physiological bite, depending on the type of face. Primarycomputer-tomographic dimensions of the width of the crowns of teeth, the width of theteeth at the anatomical neck, the distance from the anatomical neck to the apex of the rootand the distance from the middle of the cutting edge to the apex of the root of the teeth inthe vestibular-tongue direction, as well as the cephalometric parameters of 44 boys and 50girls with normal occlusion close to the orthognathic bite received from the data bank of theresearch center of the National Pirogov Memorial Medical University, Vinnytsya. Face typewas determined using the Garson morphological index. The statistical processing of theobtained results was carried out using the statistical software package "Statistica 6.0" usingnon-parametric estimation methods. In boys and girls with physiological bite with differenttypes of face the boundaries of the percentile width of the crowns width, the width of theteeth at the level of the anatomical neck, the distance from the anatomical neck to theapex of the root and the distance from the middle of the cutting edge to the apex of the rootin the vestibular-tongue direction are determined. The analysis of gender differences inthe size of the teeth showed that all the indicators of the distance from the anatomical neckto the apex of the root and the distance from the middle of the cutting edge to the apex ofthe root of the corresponding teeth in the vestibular-tongue direction in young boys with abroad face are significantly higher than that of girls with a wide face; the vast majority of thesize of the width of the crowns of teeth and the width of the teeth at the level of theanatomical neck in the vestibular-tongue direction in the young boys with a broad face arealso significantly higher than that of girls with a wide face. Reliable or tendentious differencesin computed-tomographic sizes of the teeth in the vestibular-tongue direction betweengirls with a very wide and wide face are not established. The results broaden theunderstanding of the anatomical structure of permanent teeth in young boys and girls ofPodillia with a physiological bite with different types of faces, which will allow dentists toimprove the efficiency of treatment of defects in teeth and dentitions.

Abstract Objective: To establish gender-specific normative data for Polish children at the age of 10 years. Materials and Methods: Thirty-nine boys and 34 girls (mean age 10.37, SD = 0.52) of Polish ethnicity were selected based on the following criteria: Class I molar relationship, lack of crossbite or scissor-bite, positive overjet and overbite less than 5 mm, adequate amount of space in both dental arches, no visible asymmetry, and good facial proportions. Lateral cephalograms of each subject were scanned and analyzed with the use of NemoCeph NX2005 software. Descriptive statistics (mean and standard deviation) were calculated for all measured variables. Independent t-tests were performed to assess the intergender differences. The results were compared to the published norms of other white populations. Normative data were presented in the tables. Results: Intergender differences included anterior cranial base length (sella-nasion), total and lower anterior facial height (nasion-menton and ANS-menton, respectively), posterior facial height (sella-gonion), SNA angle, point A to nasion perpendicular distance, pogonion to nasion perpendicular distance, and facial axis. Conclusions: Polish 10-year-old boys had a larger anterior cranial base, and larger total anterior, lower anterior and posterior facial heights than girls. The maxillae and chin protrusion were more pronounced in girls.

PURPOSE: Sex determination is one of the most important aspects of the personal identification in forensic medicine. The present study thus aimed to assess the value of cephalogram in determining sex by applying eleven linear and an angular cephalometric variables measured on lateral cephalograms among Iranians.METHODS: In a cross-sectional study, 11 linear and 1 angular cephalometric measurements were studied. Those are: basion to anterior nasal spine, upper facial height, length of cranial base, total face height, frontal sinus height, mastoidale to sella-nasion plan, mastoidale to porion-orbital plan, mastoid height from cranial base, mastoid with at the level of cranial base, mandibular effective length (central condyle to prognation), occipitofrontal diameter, and gonial angle. Measurements were assessed in 150 individuals (75 males and 75 females) aged 25 to 54 years. After preparing lateral cephalograms, the cephalometric measurements were analyzed using PACS software. SPSS version 22.0 was used for analysis. P values of 0.05 or less were considered statistically significant.RESULTS: With the exception of gonial angle, comparison of lateral cephalometric indices between two sexs showed greater values in males than in females (p<0.001). In general, almost all of the cephalometric measurements were found reliable to distinguish between male and female sex skulls with a high sensitivity (100%) and specificity (97.3% to 1000%).CONCLUSION: The cephalometric measurements used in this study are able to differentiate with high specificity and sensitivity between male and female skull

Three-dimensional (3D) computer-aided simulation has revolutionized orthognathic surgery treatment, but scarce 3D cephalometric norms have been defined to date. The purposes of this study were to (1) establish a normative database of 3D Burstone cephalometric measurements for adult male and female Chinese in Taiwan, (2) compare this 3D norm dataset with the two-dimensional (2D) Burstone norms from Caucasian and Singaporean Chinese populations, and (3) apply these 3D norms to assess the outcome of a computer-aided simulation of orthognathic surgery. Three-dimensional Burstone cephalometric analysis was performed on 3D digital craniofacial image models generated from cone-beam computed tomography datasets of 60 adult Taiwanese Chinese individuals with normal occlusion and balanced facial profile. Three-dimensional Burstone analysis was performed on 3D image datasets from patients with skeletal Class III pattern (n = 30) with prior computer-aided simulation. Three-dimensional Burstone cephalometric measurements showed that Taiwanese Chinese males had significantly (p < 0.05) larger anterior and posterior facial heights, maxillary length, and mandibular ramus height than females, with no significant (p > 0.05) difference for facial soft-tissue parameters. The 3D norm dataset revealed Taiwanese Chinese-specific facial characteristics, with Taiwanese presenting (p < 0.05) a more convex profile, protrusive maxillary apical bases, protruding mandible, protruding upper and lower lips, and a shorter maxillary length and lower facial height than Caucasians. Taiwanese had significantly (p < 0.05) larger maxillary projection, vertical height ratio, lower face throat angle, nasolabial angle, and upper lip protrusion than Singaporean Chinese. No significant (p > 0.05) difference was observed between 3D norms and computer-aided simulation-derived 3D patient images for horizontal skeletal, vertical skeletal, and dental measurements, with the exception of two dental parameters (p < 0.05). This study contributes to literature by providing gender- and ethnic-specific 3D Burstone cephalometric norms, which can assist in the multidisciplinary-based delivery of orthodontic surgical care for Taiwanese Chinese individuals worldwide, including orthodontic management, computer-assisted simulation, and outcome assessment.

ABSTRACT Objective: To analyze a possible correlation between different measures in the definition of vertical facial types. Materials and Methods: This is an analytical observational study about 95 lateral teleradiographs of Caucasian individuals with normal occlusion, of which 54 were male (56.84%) and 41 female (43.16%), aged between 15 years and 2 months old and 21 years and 4 months old. Facial types were divided into dolichofacial, mesofacial, and brachyfacial, according to the standards established by different authors. A relationship between these measurements was verified using total agreement analysis and the Kappa method, with the interpretation suggested by Landis and Koch. Results: Kappa was considered fair for Jarabak X VERT (0.22 and 60%) and slight for Jarabak X SN.GoGn (0.06 and 36.8%). Conclusions: Cephalometric studies often present different interpretations on the description of vertical facial types. In this study, the lowest agreement was between Jarabak and SN.GoGn. Such difference in interpretation may lead to distinct therapeutic approaches and thus different results.
