Abstract
Mandibular fractures are common and normally require surgical treatment.
The ideal method for treating these fractures is rigid or stable internal
fixation by means of plates or miniplates
(1)
Early techniques used to immobilize Mandibular fractures included
bandage immobilization and intermaxillary fixation. Fixation of the maxilla
to the mandible was first used in 1992
(2)
Occasionally when there has been an excessive delay in treating a
fractured mandible, interpositional tissue between the two bone ends can
prevent a satisfactory closed reduction. (In this situation an open reduction
is necessary to remove the soft tissue between the fragments). Nonunion is
distinguished from delayed union by the potential of the bone to heal.
Delayed union is a temporary condition in which adequate reduction and
immobilization eventually produces bony union. On the other hand,
nonunion may persist indefinitely without evidence of bone healing unless
surgical treatment is undertaken to repair the fracture. Nonunion is generally
characterized by pain and abnormal mobility following treatment.
Malocclusion may be present in dentate cases and mobility exists across the
fracture line. Radiographs demonstrate no evidence of healing and in later
stages show rounding off of the bone ends. Delayed and nonunion occur in
about 3% of fractures

Wound healing occurs in three distinct but overlapping phase.
