## TL;DR

This study compares different angles used in orthodontics to assess jaw discrepancies, finding Yen and Beta angles more reliable than ANB.

## Contribution

The study introduces Yen and Beta angles as more accurate alternatives to the ANB angle for diagnosing sagittal jaw issues.

## Key findings

- Yen and Beta angles showed the strongest correlation and predictive value for sagittal dysplasia.
- Wits appraisal was found to be less reliable compared to other angles.
- K angle was more reliable than ANB but less than Yen and Beta angles.

## Abstract

Accurate assessment of sagittal skeletal discrepancies is crucial in orthodontic diagnosis. The commonly used ANB angle has limitations
influenced by craniofacial growth and landmark variability. This study compared Yen angle, Beta angle, Wits appraisal and K angle with
ANB angle in 120 cephalograms of adults aged 18-30 years. Statistical analysis showed Yen and Beta angles had the strongest correlation
and predictive value, followed by K angle, while Wits appraisal was less reliable. Hence, Yen and Beta angles serve as more dependable
alternatives to ANB angle in diagnosing sagittal dysplasia.
