Materials And Methods:
Patients satisfying the inclusion and exclusion criteria underwent arch bar application followed by either closed reduction or open reduction with internal fixation. Pre-operatively: OHI, GI, radiographically displacement, no. of fractures, Perioperatively: Duration of procedure, glove perforation, wire prick injuries, screw loosening/wire breakage, stability, and comfort intraoperatively. Postoperatively: OHI index and GI index, screw loosening/wire breakage, arch bar removal time and glove perforation, wire stick injury, root perforation. Chi-square test was used for categorical data in tabular and graphical forms.
Results:
A statistically significant difference was observed in the postoperative OHI score, GI score, mean placement time, and mean removal time between Group A and Group B. The stability of the arch bar was matched between the groups. Screw loosening was non significant, Glove perforation was significant between Group A and B. Wire stick injury was non-significant between group A and B.
Conclusion:
The Hybrid Arch Bar proved to be superior to Erich's Arch Bar in terms of time efficiency, stability, comfort, and oral hygiene. Overall, the benefits of the Hybrid Arch Bar outweigh its disadvantages.
