Abstract: Abutment is an important restoration structure for connecting implants and upper restorations, the characteristics of the abutment, such as the abutment materials, the manufacturing method, the color, the shape of the gingival profile, and the surface properties of the abutment will have different effects on the gingival aesthetics. More and more patients have higher and higher aesthetic requirements for the anterior region. The gingival margins, the vertices of the gingiva, the gingival papilla, the pink aesthetic score of the gingiva(PES) and gingival contours are important factors affecting the aesthetics of the gingiva in the anterior region. The purpose of this article is to introduce the characteristics of the abutment and the thickness of the gingiva surrounding the implant and perceptual aesthetics, Strive to provide clinicians with appropriate implant abutments in the anterior aesthetic region.

Key words: implant prosthetic abutments, gingival aesthetics, thickness of gingiva, perceptual aesthetics
