Establishing the constraints and loading. (A) The bilateral temporomandibular joints were completely constrained. (B) For incisal loading, a 66.7-N compressive load was applied to the central incisors perpendicular to the occlusal plane. (C) For contralateral molar loading, a 260.8-N compressive load was applied to the occlusal surface of the right first molar perpendicular to the occlusal plane.
