Abstrakt: Aims and Objectives: To compare the efficacy of titanium 2.0-mm curved locking strut plate and 2.0-mm straight locking miniplate with regard to their intraoperative use and the stability of fixation achieved both, clinically and radiographically.
Materials and Methods: Forty patients with 62 sites of mandibular fractures requiring open reduction and internal fixation were included in the study. The sample was divided into two groups of twenty patients each depending upon whether patient received three-dimensional 2.0-mm locking curved strut plate (group A) or 2.0-mm straight locking miniplates (group B). Mouth opening, teeth in the fracture line, degree of displacement, time taken, neurosensory and bite force evaluation were done preoperatively, 1st, 7th day, 2nd week, 4th week, 6th week and 12th week postoperatively.
Results: Positive correlation was found between preoperative and postoperative bite force values at subsequent follow-up weeks. At 3rd month evaluation, the change in bite force from the previous follow-up visit was significantly greater in group A (locking strut plate) than group B (locking miniplate) in the incisor, left molar and right molar region. Statistically significant difference was observed between the two groups regarding time taken ( P  < 0.016) depicting less time taken for placement of three-dimensional 2.0-mm locking curved strut plate(group A) 20.30 ± 4.85 min as compared to 27.30 ± 6.82 min for fixation with 2.0 mm straight locking miniplates in group B.
Conclusion: The findings were suggestive that the both systems had better adaptation during fixation, comparable radiographic reduction and increased stability in postoperative period. However, 3D locking strut plate took relatively lesser operative time, offered good rigidity and better stabilization of fractured segments in three dimensions along with significant improvement in the masticatory bite force postoperatively.
