Abstract:

Gingival biotype refers to the morphological characteristics of periodontal and tooth tissues. Gingival biotype is a reference factor in predicting the success rate of esthetic treatments, such as restoration, implantation, and periodontal surgery. Differences were observed in the gingival biotypes among individuals and the responses of different gingival biotypes to external stimulation. Thin gingiva biotype was prone to gingival recession after treatment, and thick gingiva biotype was prone to inflammatory changes, such as probe bleeding. Thus, the evaluation of gingival biotype is extremely important from the start of treatment plan to the final restorative placement to provide excellent esthetics. This review paper summarized several methods of assessing gingival biotype.

Key words: gingival biotype, gingival thickness, measurement method
