Effect of the shape of mini plate on the stability of mandibular fracture

Abstract

Introduction: Both thickness, width-length and shape of the miniplate along with number and dimensions of the screws play a role for fracture stability however the researches that studied the effect of the shape are few. Aim: Aim of this work is to study the effect of the miniplate shape on fracture stability while the other factors are fixed. Materials and Method: Specially designed straight and L shaped miniplates both are equal in length, width and number of the holes, used to manage symphyseal fracture of acrylic mandible whether in single or double manners the stability of the fracture was invstigated through bending and torque test. Results: L shaped plate was more stable than straight plate on both bending and torque tests. Conclusion: Changing the shape of the plate may have a role for fracture stability while other factors are fixed.
