Relationship Between Posterior Cranial Base Inclination And Skeletal Jaw Patterns, Ratna Sugiartati Arif, Maria Purbiati, Krisnawati E. Tarman

Taiwanese Journal of Orthodontics

Introduction: Variations in nasion (N) could influence the measurement of ANB, thus affecting the interpretation of skeletal jaw relationship. Points sella (S) and N represent the anterior cranial base, a crucial role in determining the skeletal jaw patterns. Improper S-N line can affect results of lateral cephalometric analysis, as a highly tilted S-N line relative to the Frankfort Horizontal Plane (FHP) can lead to discrepancies between the analysis results and true morphology. Therefore, alternative methods, such as analysing the posterior cranial base (sella to basion, S-Ba), are needed to establish a diagnosis.

Objective: To determine relationship between posterior …
