Comparison of the Planas Functional Masticatory Angle Across Deciduous, Mixed, and Permanent Dentition Stages: A Cross-Sectional Pilot Study

. This pilot study suggests PFMA decreases with dentition progression, reflecting physiological occlusal adaptation. Class I predominance supports functional symmetry, but PFMA-molar class associations require larger samples. Longitudinal studies are needed to further explore the clinical applicability of PFMA as a functional descriptor of masticatory adaptation.
