Abstract
The aim of our study was to compare the biomechanical stability of three different
systems used to fix mandibular condylar fractures on synthetic polyurethane mandibles
using a servohydraulic testing unit and finite element analysis (FEA). We measured
the resistance to displacement loads causing 1.75 and 3.5 mm displacements of the fragments, and the maximum resistance values before failure
of the fixation system in 30 condylar necks of 15 polyurethane mandible models. The
three subgroups investigated were arranged as a triangular plate (n = 10), a quadrangular plate (n = 10), and a straight miniplate (n = 10). The most successful fixation pattern was achieved with two straight four-hole
miniplates. However, the triangular plate can easily be applied as a second option
by an endoscopic approach. The rectangular plates showed no success in mandibular
condylar fractures.
