Abstract

Aim: This study aimed to compare the clinical outcomes of a conventional Erich's arch bar vs a modified screw-retained arch bar in maxillomandibular fixation of mandibular fracture. Materials and methods: This parallel-arm randomized control trial included patients from the outpatient clinic with single favorable mandibular fractures that are indicated for closed reduction. They were subjected to maxillomandibular fixation using conventional Erich's arch bars in the control group and modified screw-retained arch bars in the study group. The outcome measures included operating time, glove perforations, postoperative pain, oral hygiene, fixation stability, occlusion, and mucosal coverage. Results: A total of 20 patients (12 males and 8 females) with a 1:1 allocation ratio were included. There was a significant statistical difference regarding operation time and number of glove perforations in favor of group B as p < 0.001, p = 0.007, respectively. There was a significant statistical difference regarding pain after 1 day (p < 0.001), 1 week (p < 0.001) in favor of group B, and at 4 weeks (p = 0.015), and 6 weeks (p = 0.002) in favor of group A. Regarding oral hygiene at 1 week (p = 0.021) and at 6 weeks (p < 0.001), there was a significant statistical difference in favor of group B. Regarding mucosal coverage at 6 weeks, there was a significant statistical difference in favor of group A (p = 0.005). Conclusion: The modified screw-retained arch bar can be considered an alternative to conventional arch bar as it provided less application time and better operator safety. It also showed better patient satisfaction regarding pain and oral hygiene. Clinical significance: Maxillomandibular fixation with the conventional technique was modified to screw-retained arch bar which is less time-consuming and provides better patient and operator satisfaction.
