Introduction: For a long time Champy’s Miniplates and Lag screws remained as primary methods of fixation of mandibular fractures.
Both miniplates and lag screws have their specific advantages. This prospective study was conducted to compare the efficacy and
surgical outcomes of treatment of mandibular fractures using either titanium miniplates or titanium lag screws for internal fixation.
Materials and Methods: 200 patients were selected for the study and they were evaluated pre and post-operatively on various
parameters. Patients were divided equally into two groups. One group was treated with titanium miniplates (group M) and other
group by titanium lag screws (group L). Operating time was recorded and post-operative complications were observed over regular
interval of time.
Results: Mean preoperative distance at various points on fracture line in group M was 1.7930, 2.6440, 2.4330 respectively while
in group L it was 2.7560, 2.4950, 2.2230 respectively. There was significant decrease in distance between fracture segments post-
operatively. The mean operative time for titanium lag screw fixation was 80.10 mins while for miniplates it was 100.50 mins. Post-
operative complications were less in group L when compared to group M.
Conclusion: Lag screw has definite advantage over miniplates in terms of time duration of surgery, proper reduction and postopera-
