Fig. 4: Mandibular kinematics during left group biting.

a The displacement patterns of hard and FGM[90–0] prostheses (mediolateral, anteroposterior, craniocaudal, and magnitude) during left group biting. b The correlation and Euclidean distance between the displacement patterns of the hard, FGM[90–0], FGM [90–10], and FGM [90–20] designs against the intact mandible during the INC and LGF biting tasks.
