Digital smile design for gummy smile correction

Abstract

Some tools can be used as an aid to the surgical planning for gummy smile correction, such as digital smile design (DSD), which allows to determine patterns of harmony and eventual asymmetries between teeth and gums. This work aims to report a gummy smile correction using DSD as reverse planning. The clinical examination revealed the presence of gummy smile and extensive bone exostosis in the premolar region. DSD was performed in the upper arch, determining the amount of gingiva to be removed, thus providing more safety and precision to the procedure. The surgery was performed by performing using an internal bevel incisions, detachment of a full thickness flap, and osteotomy and osteoplasty. After 6 months of preservation, there was an increase in the clinical crown of the teeth, with smile harmony, less exposure of the gingiva in the smile and a high level of patient aesthetic satisfaction.
