Correlation of 3D Morphometric Changes, Kinematics, and Muscle Activity During Smile.

Objective: Knowing the morphological, kinematic, and electrophysiological parameters of the smile in healthy individuals may contribute to evaluating, planning, and monitoring the smile reanimation. This study aimed to determine the correlation between 3D morphometric changes, movement kinematics, and muscle activity in the facial soft tissue of healthy individuals.

Method: In this cohort study, 20 volunteers were selected from healthy individuals with no facial disorders.
