Sorriso gengival: abordagem ortodôntica e periodontal
Advisor(s)
Abstract(s)
A região anterior da maxila é considerada pelos pacientes como a mais importante em termos de estética, pelo que as alterações na zona gengival podem comprometer a harmonia e a simetria do sorriso. Entre essas alterações destaca-se o excesso de exposição gengival.
O termo “sorriso gengival” é utilizado quando existe um excesso de exposição de gengiva durante o sorriso. Contudo, não existe consenso, em termos de literatura, relativamente à quantidade de gengiva exposta durante o sorriso para este ser considerado gengival, pois os valores variam entre 2 e 4mm.
O sorriso gengival é o resultado de uma combinação de variáveis tais como alterações gengivais, esqueléticas, musculares, dentárias, labiais externas entre outras. O tratamento depende da etiologia e do diagnóstico clínico. Nesse sentido e através de uma revisão bibliográfica, a autora deste trabalho teve como objectivo abordar as diversas técnicas para a correcção do sorriso gengival, nomeadamente gengivectomia, reposicionamento ortodôntico, aplicação de toxina botulínica e cirurgia óssea ressetiva para alongar a coroa clínica.
The anterior region of the maxilla is considered by the patients as the most important in terms of aesthetics, so that changes in the gingival area may compromise the harmony and symmetry of the smile. Among these changes, it is worth noting the excessive gingival exposure. The term “gingival smile” is used when there is excessive gum exposure during the smile. There is, however, no consensus in terms of the literature regarding the amount of gingiva exposed during the smile to be considered gingival; values vary between 2 and 4mm. The gingival smile is caused by a combination of variables such as gingival, skeletal, muscle, dental changes, external labia, among others. Treatment depends on the etiology and clinical diagnosis. In this sense, through a bibliographic review, the author of this work had as per objective to approach the various techniques for the correction of gingival smile, namely, gingivectomy, orthodontic repositioning, botulinum toxin application and the resective bone surgery to elongate the clinical crown.
