- Original description
This research addresses obstructive sleep apnea syndrome (OSAS), affecting 6-12% of French adults, often treated with mandibular advancement devices (MADs). MADs may lead to occlusal modifications, causing a 50% treatment abandonment rate. The study employs surface electromyography to assess masticatory muscle activity before and during MAD use, correlating it with occlusal changes after 6 months. The primary goal is to determine dental displacement profiles post-6-month MAD treatment, providing insights for personalized care and minimizing treatment failures.Read full original descriptionShow less
