Cephalometric Evaluation of Anterior Cranial Base Slope in Patients with Skeletal Class I Malocclusion with Low or High SNA and SNB Angles
Öz: Objective: In the cephalometric analyses, it is observed that both SNA and SNB angles are higher or lower than normal for someskeletal Class I patients. The aim of this study was to assess the correlation between low or high SNA, SNB angles, and anterior cranialbase (ACB) slope.Methods: One hundred and seventeen skeletal Class I patients (45 males with a mean age of 14.5 years, 72 females with a mean ageof 14.4 years) were evaluated in three groups. Group 1(n=40): Control group, individuals with normal SNA(82°±2°), and SNB(80°±2°)values. Group 2 (n=37): Patients with SNA>84° and SNB >82°, Group 3 (n=40): Patients with both SNA and SNB values lower than 78°.On the cephalometric radiographs, three angulars (SN / FH; anterior cranial base, Ba-S / FH; posterior cranial base, SN-Ba; total cranialbase) and seven linear (S-FH, N-FH, Δ, Ba-S, Ba-N, Ba-A, Ba-B) measurements were performed to analyze the vertical and horizontalpositions of the S and N points and thereby the ACB slope. One-way ANOVA and Kruskal Wallis tests were used for statistical analysis.Results: The ACB slope was observed to be relatively flatter in Group 2, and steeper in Group 3 (p<0.05). The location of the S and Npoints in the sagittal plane did not significantly affect the SNA and SNB. However, the vertical position of the S and N points was afactor determining the inclination of the ACB, therefore the SNA and SNB.Conclusion: ACB slope directly affected SNA and SNB measurements. ACB might lead to misleading results when used as a reference plane.
