“…In these reports, however, the assessment of soft tissue was only performed in the lip area which was changed by the orthodontic treatment. The results of comparison of Caucasians and Japanese were generally similar to the observations of other investigators 3,[10][11][12] . Therefore, Nezu et al 12) suggested that the frequency of Japanese extraction cases for in orthodontic treatment will increase because of the retruded chin, the bilabial protrusion, the limitation of the upper molar distalization, and the improvement of soft tissue.…”

“…In addition, consideration must be given to reconstructing the symphysis by reduction genioplasty as an additional surgical operation to decrease the lower third facial height and the prominent chin. Our analysis including soft tissue measurements can clarify the morphological characteristics of orthognathic surgical cases in the Class III group better than conventional cephalometric analyses 3,6,7) even though there are still some measurement variables.…”

“…its facial, skeletal and dental components, along with a recognition of the limitations of current orthodontic therapy 14) . A number of cephalometric assessments 3,6,7,11,12) are primarily designed to harmonize the position of the teeth with the existing skeletal pattern. These analyses are commonly used for orthodontic analysis.…”

The purpose of this study was to establish a Japanese standard norm for orthognathic surgical analysis to be used in clinical applications and to clarify maxillofacial morphological characteristics in skeletal Class III malocclusions requiring orthognathic surgery. The materials were pretreatment lateral cephalometric radiographs in the relaxed lip posture from 50 subjects with skeletal Class III malocclusions diagnosed as requiring orthognathic surgery. The control group consisted of 50 subjects with normal occlusion and well-balanced faces. Detailed cephalometric measurements were recorded and analyzed statistically. The skeletal, dental, and soft tissue measurements from the normal group did not reveal any marked differences between the sexes. The Class III group exhibited a more retrognathic maxilla and prognathic mandible, a steeper mandibular plane, a more prominent chin, and a larger lower facial height in the skeletal measurements; a significant lingual inclination of the mandibular incisor in the dental measurement; and a more concave profile with prognathic mandible, a larger lower facial height, a more acute nasolabial angle and chin in the soft tissue measurements. We suggest that this analysis can be clinically useful in diagnosis, treatment planning, and posttreatment evaluation for orthognathic surgical cases who are Class III patients.

“…Various other studies on different ethnic groups distributed in many geographic locations such as Japan [5][6][7][8][9][10], China [11][12][13], Iran [4,14], Korea [15] and African ancestry negro [28,29]. These studies have proved the difference in ethnic values and the importance to have norms developed for regional population for interpretation, deformity assessment and treatment planning.…”

Primary aim Variability is characteristic of different faces and facial types, and normative data based on one population group does not represent all. Hence, this study was undertaken to establish skeletal cephalometric norms for the South Indian (Karnataka) population utilizing the norms laid by Burstones's analysis for Caucasians. Methods The sample comprised of lateral cephalograms taken in natural head position of 100 participants (50 men, 50 women). The cephalograms were traced, analyzed and interpreted using the landmarks and values given by Burstone's analysis (Cephalometric analysis for Orthognathic surgery). The student's t test, standard deviation and mean deviation were calculated to compare between two groups. Results Statistically significant skeletal differences were found between men and women of the South Indian origin in comparison to Caucasian origin. Men had decreased facial divergence, anterior maxillary dental height and proclined upper incisors. Women had marginally increased cranial base, increased midfacial height and proclined upper incisors.Conclusion Statistically significant differences were found between South Indian men and women when compared with Caucasians in certain key parameters. These differences need to be considered when analyzing the cephalogram for orthognathic surgeries. The values derived from this study may be considered to make the deformity assessment and plan surgery to get optimal results for people of south Indian origin conclusive results can be derived after conducting a study with an eager sample size.

“…Most investigators have assessed craniofacial structures of different ethnic and racial groups and established norms for each group. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] However, the evaluation of craniofacial structures by means of intracranial reference lines has been criticized for the following reasons:…”

Objective: (1) To establish cephalometric standards for the Turkish adult population, (2) to compare Turkish norms with the published standards of McNamara norms, and (3) to compare the assessment of craniofacial structure by extracranial and intracranial reference lines. Materials and Method: The main study sample consisted of 44 female and 29 male dental students aged between 19 and 29 years. All of the head films were taken in the natural head position, which was determined with 0.5-mm wire that was attached to a fluid level device to represent the true horizontal and a metal chain that was suspended in front of the cassette to check the true horizontal.
