Abstract
Aim: To evaluate the effect of customized V pattern plate fixation versus a conventional
superior-inferior mini plates fixation of mandibular angle fracture
Methodology: This work was conducted between January 2019 to January 2020 . A total of
26 pateients with unilateral unfavorable mandibular angle fractures were selected from the
outpatient clinic of Oral& Maxillofacial Surgery Department, Faculty of Dentistry-Cairo
University and Ahmed Maher Teaching Hospital to participate in this study.
Results: The results showed that there was a statistical difference between study group and
control group regarding the post-operative occlusion and bone density along the fracture line.
There was no statistical difference (p value > 0.05) in postoperative panoramic radiographs
that were taken within the postoperative first week. There was a statistically significant of
maximal mouth opening in both groups in postoperative first week and first month. However
there was no statistically significant of maximal mouth opening in the postoperative third
and sixth months in both groups in which maximal mouth opening became normal.
Conclusions: A customized V pattern plate design as comparble to the conventional superior
-inferior miniplates is an appropriate plate structure for unfavorable mandibular angle
fracture,it ensures a proper alingment of the fracture with plate fixation and adequate
postoperative radiographical results . It reduces the chance of post operatrive complications
such as occlusal discrepancy, and inferior alveolar nerve injury.
