OBJECTIVE:To determine the mean soft tissue facial profile for Circassian adults as determined by Legan–Burstone cephalometric analysis.MATERIALS AND METHODS:71 lateral cephalometric radiographs for nongrowing Circassian adults with normal occlusion were traced and accurately measured.RESULTS:With regard to facial form analysis, Circassian adults showed higher facial convexity angle, retruded mandible, and obtuse lower face–throat angle. When compared with lip form norms, Circassians showed increased nasolabial angle, deeper mentolabial sulcus, and increased maxillary incisor exposure. Comparison between men and women showed that mentolabial sulcus depth was significantly increased in Circassian men compared with Circassian women.CONCLUSION:The results of this study showed that soft tissue facial profiles for Circassians and Caucasians are different in certain values. Such differences should be taken into account when formulating a treatment plan for Circassian patients seeking orthodontic treatment and orthognathic surgery.

“…Moreover, the studies of soft tissue cephalometric norms in Caucasian and Singaporean Chinese populations did not perform gender-stratified analysis [12,24], limiting a direct comparison with the current 3D Taiwanese Chinese data. The Bustone cephalometric method used in this study is a quantitative technique commonly employed for orthognathic surgical planning and outcome assessment [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. However, other methods exist which use 3D digital image-based measurements to enhance the arsenal of strategies and possibilities of clinicians.…”

“…In 1978, Burstone developed the "Cephalometrics for Orthognathic Surgery" [11,12]-a detailed analytical method which is widely accepted and used in the fields of orthodontics and orthognathic surgery [13][14][15][16][17][18][19][20][21][22][23][24]. This two-dimensional (2D) image-based cephalometric method includes clinically useful facial bone (linear and angular measurements in horizontal and vertical directions) and soft-tissue (facial form and lip position) analysis [11,12].…”

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.

“…Dental, skeletal and soft tissue characteristics of a particular malocclusion can differ based on ethnicity, race, age, sex and geographical region [ 1 , 2 , 3 ]. Understanding this variation may help us to better treat our patients using individualized approaches by customizing our treatment plans that account for the above factors.…”

The dental, skeletal, and soft-tissue characteristics of a particular malocclusion can differ based on ethnicity, race, age, sex and geographical location with Class II malocclusion being one of the most prevalent malocclusions encountered in orthodontic clinical practice. The broad understanding of the characteristics of vertical skeletal and dental parameters in patients with Class II malocclusion can help clinicians to identify patterns and variations in the expression of this phenotype for better treatment outcomes. Hence, we compared the craniofacial characteristics of skeletal and dental Class II malocclusion traits from Indian and Vietnamese individuals to analyze the vertical skeletal and dental patterns in both population groups. The sample comprised of lateral cephalograms from 100 young adults with Class II malocclusion, of which fifty (25 males and 25 females) were from South India and the other 50 age- and sex-matched adults from Vietnam. The lateral cephalometric radiographs were digitized into anonymous image files and were traced and assessed for 16 vertical skeletal and dental parameters. The ANB angle was greater in males (+1.4 deg; p < 0.001) and females (+1.9 deg; p < 0.001) in the South Indian population. The Vietnamese males had a larger mandibular plane angle, articular angle, anterior facial height and lower anterior facial height compared to the Indian males. The Vietnamese females had larger mandibular plane and articular angles compared to the Indian females. The skeletal class II malocclusion was more severe in the South Indian compared to the Vietnamese adults. The Vietnamese sample showed a generalized tendency towards a more vertical skeletal growth pattern and in males this pattern seemed to be due to the dentoalveolar component. The Vietnamese females showed a tendency towards a vertical growth pattern, but without apparent contribution by the dentoalveolar component.
