Comparison of popular sagittal cephalometric analyses for validity and reliability

Abstract

All five-skeletal cephalometric sagittal analyses are reliable and can be used in orthodontic diagnosis as alternative to each other.

Evaluation of Various Sagittal Cephalometric Measurements in Skeletal Class I Individuals with Different Vertical Facial Growth Types

“…For this reason, we predict that it can be used even in individuals with different facial growth patterns. Although the limitations of this study suggest a reliability problem in terms of nasion point, and we predict that there may be errors in the geometric determination of the points used in determining the W, Yen and Beta angles (9,10,13,14,24), evaluating these measurements together will be useful in overcoming these problems. In addition, in order to evaluate the relationship between these measurements more clearly and in detail, we examined the differences in different sagittal and vertical malocclusion groups.…”

“…In previous studies, the relationship between these measurements was evaluated according only to the sagittal malocclusion classes (4-6, 9-14). Qamaruddin et al reported that the Beta, W and Yen angles showed significant changes in different sagittal malocclusion groups in which the anteroposterior relationship of the jaws was defined (10). In this study, the lowest values were obtained in the Class II malocclusion group, while the highest values were obtained in the Class III malocclusion group, and we observed that there was only a difference in the Wits appraisal, Pog-Nperp, Beta, W and Yen angle values in individuals with different vertical facial growth types (10).…”

“…Previous studies conducted among various populations examined the relationships between the Wits measurement and the ANB, Beta, Yen and W angles, but did so using only sagittal evaluations (9)(10)(11)(12)(13)(14). No study has shown the relationship between these angles according to different growth types of the face in the vertical dimension.…”

“…They are therefore more sensitive to the changes in the vertical dimension of the jaws used in a McNamara cephalometric evaluation (7). On the other hand, the use of the Beta angle, Yen angle and W angle, which are considered alternatives to the aforementioned measurements, has increased in recent years (4)(5)(6)(9)(10)(11)(12)(13)(14). However, it has long been known that orthodontic malocclusions arising from the difference in the lower and upper jaw positions occur effectively in all three planes (15).…”

Accuracy of different cephalometric analyses in the diagnosis of class III malocclusion in Saudi and Yemeni population

“…Another study conducted by Qamaruddin et al . [ 26 ] in 2017 in Pakistani population indicated that the W angle showed high diagnostic value and high correlation with other cephalometric analyses in diagnosis of skeletal discrepancies.…”
