Cephalometric analyses of the craniofacial pattern using the Jarabak analysis

Abstract

Background: For an accurate orthodontic diagnosis and management, knowledge of face development and progression is required. Objective: To evaluate the linear cranial base (LCB) and angular cranial base (ACB) measurements in various Anterior and Posterior (AP) skeletal correlations, research study used Bjork-Jarabak evaluation. Material and Methods: A total of 220 young participants presenting (120 females and 100 males; average ages of 19.34 ± 2.51 and 24.84 ± 2.81 years, correspondingly) at the Multan Medical and Dental College, Multan from March 2022 to September 2022, Pakistan, served as the basis for this retrospective cross-sectional study. Results: In comparison to Jarabak's standards, male dimensions revealed significant differences in the articular angle, AP cranial bases, ramus height, jaw length, anterior face height while women displayed low significant differences, with the exception of mandibular body length, which is longer in Pakistani women. Conclusion: Skeletal differences between Pakistani man and women were considerable, and a contrast to the study of Bjork Jarabak's standardized linear and angular values was also noteworthy.

Cone Beam Computed Tomographic Evaluation of the Maxillary Sinus in Different Craniofacial Patterns

“…Different methods in the literature were used to assess the craniofacial type. In our study, we have made this discrimination according to the Jarabak's ratio [8,9] . Craniofacial patterns refer to the unique skeletal structures and proportions of the face and skull.…”

“…This ratio is obtained by the formula posterior facial height / anterior facial height x 100. The measurements of facial height were done from the nasion to the menton for the anterior face and from the sella to the gonion for the posterior face [8] . (figure 1,2)…”

“…Group 1: Normal growth pattern when the ratio is between 62-65%, Group 2: Hyperdivergent growth pattern/long facial pattern, when this ratio is less than 62%. Group 3: Hypodivergent growth pattern/short facial pattern, when the ratio is higher than 65% [8,9] .…”
