dc.description.abstractO sorriso gengival caracteriza-se pela exposição excessiva de tecido gengival durante o sorriso, podendo causar impacto estético e psicossocial negativo. Sua etiologia é multifatorial, envolvendo fatores musculares, dentários, gengivais ou esqueléticos. Entre as alternativas terapêuticas minimamente invasivas, a aplicação de toxina botulínica tipo A (BTX-A) destaca-se pela eficácia, previsibilidade e rápida recuperação. O objetivo deste trabalho foi relatar um caso clínico de correção de sorriso gengival por meio da aplicação de toxina botulínica tipo A (Dysport®), evidenciando seus resultados clínicos e a satisfação da paciente. O estudo foi aprovado pelo Comitê de Ética em Pesquisa sob parecer no 8.048.998. Paciente do sexo feminino, 22 anos, atendida na clínica odontológica da Universidade Christus, Fortaleza, Ceará, apresentava insatisfação estética decorrente da excessiva exposição gengival ao sorrir. Após avaliação clínica e diagnóstico de erupção passiva alterada associada à hiperatividade muscular do lábio superior, foi instituído plano terapêutico com aplicação de BTX-A nos músculos elevadores do lábio superior. Observou-se redução significativa da exposição gengival, melhora estética do sorriso e elevado grau de satisfação da paciente, sem intercorrências. Entre as principais vantagens da técnica destacam-se sua natureza minimamente invasiva, segurança, rápida execução e previsibilidade dos resultados. Entretanto, apresenta como limitações o caráter temporário dos efeitos, com duração média de três a seis meses, e a necessidade de reaplicações periódicas. Complicações são incomuns, mas podem incluir assimetria do sorriso, edema, hematoma local e resultados estéticos insatisfatórios quando a técnica não é adequadamente executada. Conclui-se que a aplicação de toxina botulínica tipo A constitui uma alternativa segura e eficaz para a correção do sorriso gengival em casos selecionados, promovendo melhora estética e aumento da autoestima dos pacientes.pt_BR

dc.description.resumo_abstractGummy smile is characterized by excessive gingival display during smiling, which may negatively affect facial aesthetics and psychosocial well-being. Its etiology is multifactorial and may involve muscular, dental, gingival, or skeletal factors. Among the minimally invasive therapeutic alternatives, botulinum toxin type A (BTX-A) has emerged as an effective and predictable approach with rapid recovery. This study aimed to report a clinical case of gummy smile correction using botulinum toxin type A (Dysport®), highlighting its clinical outcomes and patient satisfaction. The study was approved by the Research Ethics Committee under approval number 8.048.998. A 22-year-old female patient treated at the dental clinic of Christus University, Fortaleza, Ceará, Brazil, reported dissatisfaction with the excessive gingival display when smiling. Following clinical examination and diagnosis of altered passive eruption associated with upper lip muscular hyperactivity, a treatment plan involving BTX-A injections into the upper lip elevator muscles was established. A significant reduction in gingival exposure, improvement in smile aesthetics, and a high level of patient satisfaction were observed, with no adverse events reported. The main advantages of this technique include its minimally invasive nature, safety, rapid application, and predictable outcomes. However, its limitations include the temporary effect, which typically lasts three to six months, requiring periodic reapplications. Although uncommon, complications may include smile asymmetry, edema, local bruising, and unsatisfactory aesthetic outcomes when the procedure is not properly performed. In conclusion, botulinum toxin type A represents a safe and effective alternative for the correction of gummy smile in selected cases, contributing to improved smile aesthetics and enhanced patient self-esteem.pt_BR
