INTRODUCTION: Both earlier and recent studies have relied exclusively on the ANB angle to quantify malocclusion. Since the ANB angle is measured at the nasion, variations of the relative position of the nasion between populations may influence the reliability of ANB angle for malocclusion classifications. The Wits appraisal offers an alternative that excludes variability from skeletal differences beyond the jaws. However, few studies have examined the Wits appraisal relationship with ANB angle, and none in South Africa, leaving the interpretation of ANB measurements in local populations uncertain. AIMS AND OBJECTIVES: This study aimed to assess the efficacy of the ANB angle for skeletal malocclusion by correlating it with the Wits appraisal. DESIGN: A cross-sectional quantitative approach. METHODS: A total of 114 lateral cephalograms were sampled and measured using ImageJ software. Spearman's correlations were performed between ANB angles and Wits appraisal using PAST statistical software. RESULTS: All correlations were statistically significant. The ANB angle and Wits appraisal showed a moderate correlation in the entire sample, but stronger in the negative category and weak in the positive category. CONCLUSION: The ANB angle was not considered consistently reliable to distinguish between malocclusion classes because of the considerable lack of agreement with the Wits appraisal measures.
