• Abstract:

  Since 2019, the Federal Council of Dentistry (CFO) has regulated orofacial harmonization as a dental specialty in resolution 198/2019, given that dental surgeons are professionals capable of competently performing facial aesthetic procedures. Among the procedures that cover facial harmonization, botulinum toxin stands out, a neurotoxin that blocks the transmission of nervous stimulus and reduces the potential for muscle contraction. Botulinum toxin presents itself as a minimally invasive technique with both aesthetic and therapeutic applications in the area of dentistry, presenting a low risk of adverse effects with safe and effective protocols. The mechanism of action of botulinum toxin is to temporarily inhibit the neuromuscular junction by blocking the release of acetylcholine in response to a nerve impulse. Given the above, the central objective of the present study was to describe the mechanisms of action of botulinum toxin in facial aesthetic procedures. To this end, a bibliographical search was carried out in the Google Scholar, Pubmed, and Scielo databases.
