A prospective study was conducted among patients who presented with isolated mandibular fracture which required active management over a 3–years period at the maxillofacial unit at D.J. College of Dental Sciences and Research Modinagar India.  A total of 32 cases was included in the study & were divided in two groups:  fracture reduction intra–operatively by manual method (non IMF group) & inter–maxillary fixation (IMF group). All the patients were postoperatively assessed clinically for occlusion and radio graphically (i.e. orthopantomographs) for anatomical reduction of fracture fragments.  Patients were followed up for minimum of two weeks after surgery. The P value for operating time for IMF group & non IMF group (p= 0.000), which is highly significant. Post–operative clinical as well as radiographic assessment for occlusion & fracture reduction in both the groups were similar. Our study suggests that the use of intra–operatively intermaxillary fixation is not routinely necessary for a favorable outcome of the treatment in isolated mandibular fractures.
