Abstract
Background: Sagittal jaw discrepancies are a critical determinant in orthodontic diagnosis and treatment planning, necessitating an accurate assessment. This study aims to investigate the predictive efficacy of various sagittal parameters (ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle) in diagnosing skeletal Class I malocclusion across diverse growth patterns.
Materials and Methods: A retrospective cross-sectional analysis was conducted using lateral cephalograms of 60 patients diagnosed with skeletal Class I malocclusion. Sagittal skeletal parameters (ANB angle, Beta angle, Yen angle, W angle, and Wits appraisal) were evaluated across three distinct growth patterns (vertical, horizontal, and average). Mean and standard deviation were calculated for each parameter within each growth pattern. One-way ANOVA with post-hoc Tukey's HSD test was employed for pairwise comparisons between groups. The inter-relationship between cephalometric parameters and growth patterns was assessed using Pearson's correlation coefficient, with statistical significance set at p ≤ 0.05.
Results: A total of 60 participants (30 males and 30 females) with a mean age of 18.60 ± 4.17 years were included in the study. Highly statistically significant differences were noted for Beta and Yen angle (p ≤ 0.001), whereas statistically significant differences were noted for ANB angle. The correlation test revealed a possible association between assessed parameters in the overall sample.
Conclusion: Angular and linear parameters revealed some degree of correlation in skeletal class I malocclusion patients irrespective of their growth pattern. However, the reliability of individual parameters in accurately classifying the skeletal discrepancies among different malocclusion states should be further investigated.
