Abstrakt: Objectives: This retrospective study aimed to evaluate the relationship between the Index of Orthognathic Functional Treatment Need (IOFTN) and sagittal skeletal discrepancy (ANB angle) among orthognathic patients.
Study Design: Records of 403 orthognathic patients (229 females/174 males, aged 16-50 years) were reviewed. Malocclusion type (incisor-based), sagittal skeletal relationship (ANB angle), and IOFTN scores were documented. Spearman correlation coefficient (r) and scatter plots were utilized to examine the relationship between functional need (IOFTN scores) and sagittal skeletal discrepancy (ANB angle). Regression analyses were conducted to determine the extent to which variations in IOFTN scores could be attributed to variations in ANB angles.
Results: Class III malocclusion/sagittal skeletal pattern were most prevalent (62.3%). The Spearman correlation coefficient (r) for the entire sample was -0.297 (P < .001), indicating a weak negative correlation. Linear regression analysis demonstrated a coefficient of determination of 0.069, indicating that approximately 6.9% of the variance in IOFTN data could be accounted for by variations in ANB angles. Upon stratifying data by different malocclusions, coefficients of determination were 0.065, 0.034, and 0.089 for class I, II, and class III malocclusions, respectively.
Conclusion: The observed linear relationships between sagittal skeletal discrepancy (ANB angle) and IOFTN score were weak and lacked clinical significance.
