Research progress of gingival aesthetics evaluation in aesthetic restoration of anterior area

Gingival aesthetics is one of the factors that affect the clinical effects of prosthesis, and is particularly important in the aesthetic restoration of anterior teeth. However, gingival aesthetics involves a number of parameters for which there is no standardized evaluating criteria available so far. In addition to implant, other methods of restoration still lack recognized aesthetic evaluation systems for clinical use. At present, there are lots of solutions to improve anterior gingival esthetics, and most of the solutions can effectively improve the aesthetic effect in clinical treatment. This article reviews the aesthetics criteria of the anterior gingival area and the aesthetics restoration methods. Key words: Esthetics, dental; Gingiva; Aesthetic prosthesis
