Botulinum Toxin-A for Bruxism Using Digital Occlusal Analysis

Sponsor: Bilecik Seyh Edebali Universitesi

Summary

Bruxism is a repetitive jaw-muscle activity that may lead to tooth wear, muscle pain, headaches, and functional limitations. Current diagnostic approaches mainly rely on self-reported symptoms and clinical examination findings, which may not accurately reflect ongoing muscle activity. Digital occlusal analysis systems offer an objective method for evaluating bite force and occlusal function. The aim of this randomized, placebo-controlled clinical trial is to investigate whether a digital occlusal analysis system can objectively assess bruxism and monitor treatment response following Botulinum Toxin-A (BTX-A) injections. Thirty-six adults diagnosed with bruxism will be randomly assigned to receive either BTX-A injections or placebo injections into the masseter muscles. Clinical examinations, patient-reported outcomes, and digital occlusal measurements will be collected at baseline and at 2 weeks, 3 months, and 6 months after treatment. Primary outcomes include bite force characteristics, force distribution, occlusion time, disocclusion time, and center of force. Secondary outcomes include pain intensity, maximum mouth opening, muscle tenderness, functional limitation scores, and self-reported bruxism-related symptoms. This study aims to provide objective evidence regarding the usefulness of digital occlusal analysis in the diagnosis and follow-up of bruxism and to evaluate the effectiveness of Botulinum Toxin-A treatment using both objective and subjective outcome measures.
