Abstract
The purpose of this experimental study was to test the reliability of a single malleable
titanium miniplate using Champy's method of fixing fractures of the mandibular angle.
Eighteen sheep hemimandibles were used to evaluate 2 plating techniques. The groups
were tested with either a single non-compression titanium miniplate or a single malleable
titanium miniplate. A cantilever bending biomechanical test model was used for the
samples. Each group was tested with vertical forces using a servohydraulic testing
unit. The displacement values in each group at each 10 N stage up to 90 N were compared using 2-way analysis of variance (ANOVA). The displacement values
for the 2 groups differed significantly (p < 0.01). The variance analyses showed that the biomechanical behaviour of a single non-compression
miniplate was better than that of a single malleable miniplate. The non-compression
miniplate fixed by screws had greater resistance to occlusal loads than the malleable
plate fixed by screws, and the malleable plate alone was not sufficient to withstand
the early postoperative bite force.
