Experimental and Numerical Modeling of Screws Used for Rigid Internal Fixation of Mandibular Fractures

Table 5

Force components (N) applied to the screw implants by the fixation plate in FEA of a fractured and fixated mandible. The x-direction is along the length of the mandible, y is normal to the bone plane, and the z-direction is their cross product.

Screw location	x	y	z
Superior posterior medial	55.3	−13.2	39.4
Superior anterior medial	−57.6	8.9	−26.3
Inferior posterior medial	−67.6	−16.4	22.2
Inferior anterior medial	51.0	21.8	−30.0
