The Craniofacial Growth period from 1965 to 1974 solidified a shift toward viewing growth as a tissue-system process governed by functional matrices, foregrounding soft tissues and functional demands in shaping craniofacial form. Methodologically, researchers emphasized longitudinal growth trajectories and remodeling concepts, enabling predictions of mandibular rotation and vertical changes and aligning basic biology with clinical decision-making. The era unified postnatal growth with surgical planning, creating a cohesive framework for understanding age-related facial development.
