Background: Numerous studies suggest that examining the correlation between condylar position and skeletal pattern is crucial in orthodontics, as this relationship may influence the functionality and stability of the temporomandibular joint (TMJ). However, limited research is currently available on this topic. Objective: This study aimed to evaluate the correlation between condylar position and skeletal pattern in patients from the orthodontic clinic of the Francisco Luis Espinoza Pineda University between January 1, 2022, and June 30, 2024. Method: A retrospective cross-sectional study was conducted with 109 randomly selected patients (≥16 years) from the clinic’s total patient population. Condylar position was determined by classifying condylar displacement (anterior, centric, or posterior) using CBCT images. Skeletal class was assessed based on the A-B linear distance in the natural head position and categorized into Class I, II, or III. Descriptive statistics, Chi-square tests, and Pearson and Spearman correlations were performed using SPSS 26. Results: A centric condylar position was observed in 65.1% of patients, anterior in 21.1%, and posterior in 13.8%. Skeletal distribution showed that 57.8% of patients belonged to Class I, 32.1% to Class II, and 10.1% to Class III. No significant correlation was found between condylar position and skeletal class (r = 0.03, p = 0.72), nor were there differences by sex. Conclusion: Condylar position was not significantly associated with skeletal class, suggesting that its variability may depend on individual anatomical factors.
