Mandibular fractures are a common type of facial fractures. The surgical treatment has developed over the years due to improved understanding of biomechanics, biomaterials and scientifically based treatment outcomes. since customized fixation mechanism is more suited to the bone surface which helps to meet the requirements of a semirigid fixation. Customized Z plate is a new geometry of miniplates that may provide superior preservation of mental nerve, stability, support and easier in adaptation compared to the standard 2 miniplates system for fixation of parasymhyseal/body mandibular fractures.

Inclusion Criteria:
