TOXINA BOTULÍNICA PARA MODERAÇÃO DO BRUXISMO

Temporomandibular dysfunction (TMD) is a complex, intermittent or transient pathology with a multifactorial or biopsychosocial etiology that affects the TMJ, the muscles of mastication and musculoskeletal structures related to the neck and head. It can limit jaw movements and cause tinnitus, but its main symptom is pain. Among the parafunctions associated with TMD, bruxism is the most prevalent pathology and has a direct impact on the quality of life of the affected individual. This disorder is classified as a parafunctional habit, characterized by the habit of unconsciously clenching or grinding the teeth, which can occur during wakefulness (WB) and sleep (SB). This study aims to understand and explore the mechanism of action of botulinum toxin in controlling bruxism, as well as checking for possible adverse effects and generalities related to the therapeutic use of this substance. According to the above, TMJ dysfunction is a complex abnormality of the temporomandibular joint and/or the muscles responsible for mastication, mainly due to its multifactorial nature and the fact that it can be intermittent or transient, so that bruxism is the most prevalent pathology resulting from this process generated by TMD or capable of triggering it. In this context, botulinum toxin is seen as a successful therapeutic alternative for faster pain relief in patients due to its action on muscle activity in a minimally invasive way, combining the maintenance of balance between the components of the stomatognathic system with the preservation of health.
