Abstract

Objective: This study evaluates the efficacy of a multilayered xeomin injection technique compared to a conventional deep injection approach in managing bruxism.

Methods: Forty patients diagnosed with bruxism were divided into two groups: the control group received deep injections at four points in the masseter, while the study group received both deep and superficial injections, with internal redirection to four sites. Treatment outcomes were assessed using electromyography (EMG) to measure muscle activity, bite force measurement, Visual Analog Scale (VAS) for pain, and patient satisfaction scores, these outcomes were evaluated during different follow up intervals (Baseline, 1 month, 3 months and 6 months). Statistical analysis was conducted using SPSS, with significance set at p < 0.05.

Results: The study group exhibited significantly greater reductions in EMG activity and bite force compared to the control group (p < 0.05). Additionally, VAS scores demonstrated lower pain levels post-treatment in the study group, and patient satisfaction scores were significantly higher. The previously mentioned parameters were assessed at baseline, 1 month, 3 months, and 6 months post-treatment, with improvements starting from the 1-month follow-up and continuing through the subsequent intervals.

Conclusion: Multilayered xeomin injection into the masseter muscle provides superior therapeutic benefits for bruxism management, resulting in improved muscle relaxation, reduced bite force, and higher patient satisfaction compared to conventional deep injections. This technique may serve as a refined protocol for clinicians treating bruxism.
