Effect of plate configuration on resistance in mandibular angle fractures

Keywords: Mandibula, fracture, stabilisation

Abstract

Aim:  This in-vitro experimental study compared the biomechanical behaviors of three single-miniplate osteosynthesis configurations used in the treatment of mandibular angle fractures.

Methodology: Twenty-one synthetic polyurethane hemimandible replicas including the medullar and cortical portions were used in this study. The replicas were divided randomly into three groups (n = 5/group). Data from the three groups were compared using analysis of variance and the Tamhane T2 test. P values < 0.05 were considered to indicate significance. The replicas in all groups were fixed with 7-mm-long self-tapping screws and 2.0-mm four-hole miniplates in three different configurations external oblique, lateral angulus superior and lateral angulus inferior configuration.

Results: The replicas were tested on a servohydraulic apparatus, and the data were transmitted to a computer for analysis of peak displacement and peak force. Peak load and peak displacement did no differ significantly among the three groups..

Conclusion: This experimental study showed that the torsional forces resulting from the fixation of miniplates for the treatment of mandibular angle fracture did not differ among the three configurations tested.
