Executive Industry Relevance

Finite element analysis (FEA) models that accurately simulate surgically assisted rapid palatal expansion (SARPE) address a critical gap in predicting asymmetric skeletal responses in mature patients. This capability enhances predictive confidence at the intersection of surgical planning and device design, supporting risk-adjusted decisions in translational craniofacial research. The approach enables more reliable evaluation of expansion mechanics, directly informing cross-disciplinary R&D and device optimization.
