Figure 2:
(a) Nonlever model of the mandible illustrating a generic tooth contact, adapted from Katona [24]. The approximation to the centroidal (neutral) axis of the mandible (dashed line) is a distance ℊ below the tooth-tooth contact point. The anterior section of interest is demarcated by horizontal distance ℎ from the tooth contact. (b) FBD (free-body diagram) of the (fractured-off or imaginary) anterior segment.
