Abstract

Aim: The present study was scrutinized to evaluate efficiency of lag screw fixation in the treatment of anterior mandibular fractures.
Patients and Methods: The study was conducted on 30 patients with mandible fracture at the anterior site, treated with lag screws and was evaluated cause, the type, and the site of fracture as well as the surgical complications.
Results: In this study the major reason for the cause of mandibular fracture is due vehicle collision. The predominant type of fracture was found to be oblique type (18 patients) and saggital type (12 patients). After the lag screw fixation, the there was a significant (p<0.0001) mouth opening in 4th week and 3rd in oblique and saggital fracture respectively. Further there was a significant improvement in the mobility of fracture fragments after lag screw fixation in both the oblique and saggital fracture. Meanwhile, out of 18 patients in oblique fracture 11 patients resumed their normal activities in one week. Whilst, in the case of saggital fracture (n=12), 11 patients resumed their normal activities in one week. The occlusion was more seen in oblique type and after lag screw fixation, significant (p<0.0001) reduction was observed in both the oblique and saggital fracture. Furthermore, no infections were detected at the fractured site, hospital stay was minimal in both the fracture types and effective bony reunion was visualized based on the radiographic findings.
Conclusion: Titanium lag screw fixation was found to have good rigidity, stability, economic and less time consuming in anterior mandibular fractures
