“…In the study of Aldrees AM. et al 18 the correlation between the dental relation of the molars and the ANB angle was 57.7%, while in the study of Zhou L. et al 19 the correlation was 61%. The difference is explained with the age of the patients who were included in both studies, i.e., the presence of patients with early permanent dentition where the molars are still in the tubertuber position before their transition to Class I.…”

Introduction: Finding a simpler and more accurate approach for the analysis of sagittal relations of jaws is a big challenge. The choice is not simple, due to the variability of the points on which the ANB angle is based, which leads to the usage of an additional linear parameter such as Wits. Objective: To observe the daily involvement of the Wits appraisal and its correlation with the ANB angle, as well as to show the justification of the usage of the Wits appraisal, its stability, and modifications for obtaining a comprehensive diagnostic image. Material and methods: Literature reviews and analysis were performed by the research network ResearchGate, Academia.edu and PubMed, by searching for papers not older than 2000, with the keywords Wits appraisal, Steiner cephalometric analysis, Orthodontic cephalometry and literature from books and contemporary journals publication. Results: The variable position of the points that determine the ANB angle showed the justification for the additional use of the Wits appraisal, and a correlation was observed in normodivergent patients. The influence of the occlusal plane position on the Wits noted its disadvantage and its modification requirement in patients with increased lower face height and high FMA angle. Conclusion: Sagittal jaws relations analysis should take into consideration additional factors such as the size of the FMA angle, the inclination of the occlusal and the mandibular plane, the vertical growth. If necessary, the modification of the Wits appraisal can be used.

INTRODUCTION: Among the diagnostic tests to evaluate sagittal maxillomandibular skeletal discrepancies and the different changes that occur during growth, the following are presented: ANB angle, (Riedel 1948); the Wits Assessment, (Jacobson 1975) of linear type and the A:B Ratio (Terreros 2020), study of geometric proportions, as alternative diagnostic tests to establish the intermaxillary sagittal relationship. OBJECTIVE: To analyze the correlation of intermaxillary sagittal appreciation between angular diagnostic tests (ANB), linear (WITS) and A:B ratio (geometric proportional) in different facial types. MATERIALS AND METHODS: Comparative radiographic study with a quantitative, cross-sectional, retrospective approach in search of 55 cephalometric radiographs of boys and girls aged 8 to 13 years, descriptive-analytical design study, deductive method. RESULTS: In this study it was shown that between the ANB Angle and the A:B Ratio there is a moderate negative relationship of -0.59, between the Wits assessment and the A:B Ratio the correlation is -0.504, which indicates that there is a moderate negative relationship and Angle ANB with the Wits Rating the value is 0.501 which indicates that there is a moderate positive correlation. CONCLUSION: It is established that the ANB angle diagnostic test uses the Nasion point as a reference and that its position affects its diagnosis. There is a moderate to good correlation between the diagnostic tests ANB Angle, A:B Ratio and Wits Assessment in the determination of the intermaxillary sagittal relationship.

“…In other words, a person presenting with Class I malocclusion on Angle's classification may have a Class II or Class III skeletal pattern and vice versa. However, another study also reported a similar percentage of 57% (5). Therefore, when performing prevalence studies of malocclusion types in a region or population, it is important to distinguish how the classification is done and which type of malocclusion is being reported.…”

Prevalence studies of malocclusion should distinguish how skeletal classification was done because of the moderate correlation that exists between dental arches and skeletal patterns. The validity of using the ANB angle as a diagnostic tool to determine skeletal patterns remains questionable. This study aimed to determine the prevalence of skeletal patterns in the Malay population, their association with gender and age groups, and whether the ANB angle is a highly correlated variable in diagnosing skeletal patterns radiographically by using Principal Component Analysis (PCA). Two thousand one hundred eighty-two lateral cephalograms of Malay patients were digitally traced. Respective skeletal patterns were determined using the ANB angles. Descriptive analysis was used to describe the prevalence, whereas the association with gender and age groups were determined using the Chi-Squared and Fisher's Exact tests. PCA was done on all commonly used cephalometric variables in Class III samples. The prevalence for the Class I, Class II and Class III skeletal patterns were 41.3%, 46.1%, and 12.6%, respectively. A significant association was found between gender and skeletal patterns (p = 0.012). Most of the significant variables in principal component (PC) 1 were vertical measurements. ANB angle was not captured in the first five PCs. Class III skeletal pattern was significantly less prevalent in the Malay population when compared to other skeletal patterns, especially in males. Vertical, sagittal cephalometric measurements and incisor angulation variables were more highly correlated than the ANB angle and, therefore, may be more useful to diagnose the Class III skeletal pattern.
