Abstract
The maxillofacial trauma has increased by many folds in recent times, due to an increase in road traffic accidents (RTAs). Incidence of particularly, mandibular fractures is high as it is the most prominent and mobile bone of the facial bones.
Fractures of anterior mandible may be treated by various techniques that follow the standard principles of open reduction and internal fixation with either plates and screws or lag screws.
Our study aimed to compare the outcomes of treatment by the use of cortical lag screws versus mini plates considering stability, operative time, intraoperative difficulties, postoperative complications and cost in patients who have anterior segment mandibular fractures.
The study was conducted in the period from January 2018 to August 2019 for 20 patients with anterior mandibular fractures. The patients have been randomly classified into 2 groups, group (A) patients were fixed by mini plates and group (B) patients were fixed by lag screws.
Lag-screw fixation was a safe and effective method that has a number of advantages over plate osteosynthesis. Lag screw fixation was found to have good stability and rigidity, was inexpensive, and was less time consuming in treating anterior mandibular fractures compared with miniplates.
