Cirurgia de reposicionamento labial para correção do sorriso gengival por meio da “muscle detachment technique”: uma nova abordagem cirúrgica

RESUMO

A exposição gengival excessiva, que gera um sorriso gengival, pode representar motivo de grande queixa estética, demandando intervenção odontológica para sua correção. Uma das possíveis técnicas propostas para diminuição da exposição gengival é a cirurgia de reposicionamento labial. O objetivo deste relato de caso foi apresentar uma nova abordagem cirúrgica para correção da exposição gengival excessiva, que envolve miotomia e contenção muscular, além de suturas para reorientação de fibras musculares, o que é possível por meio da desinserção muscular proposta neste artigo – motivo da denominação “muscle detachment technique”. Após dois meses, um procedimento de aumento de coroa clínica foi efetuado e, após cicatrização, peças cerâmicas foram instaladas. A nova técnica possibilitou a obtenção de uma significativa diminuição da exposição gengival e alcance de melhor estética, sem recidiva após um período de seis meses pós-operatórios.

Palavras-chave – Sorriso gengival; Exposição gengival excessiva; Técnica cirúrgica.


ABSTRACT

Excessive gingival exposure, which generates a gummy smile, can represent a major aesthetic complaint, requiring dental intervention for its correction. One of the possible techniques proposed to reduce gingival exposure is lip repositioning surgery. The aim of this case report was to present a new surgical approach to correct excessive gingival exposure, which involves myotomy and muscle restraint, in addition to sutures for reorientation of muscle fibers, which is possible through the muscle detachment proposed in this article, which is the reason for the denomination “muscle detachment technique”. After 2 months, a clinical crown lengthening procedure was performed and, after healing, ceramic veneers were installed. The new technique made it possible to obtain a significant decrease in gingival exposure and the achievement of better esthetics, without relapse after a period of 6 months postoperatively.

Key words – Gummy smile; Excessive gum exposure; Surgical technique.
