[Research progress of the influence of gingival biotype on the prognosis of oral treatment].

The gingival biotypes, which were proposed by Ochsenbein, could be divided into thin gingival biotype and thick gingival biotype. There are several methods to judge the gingival biotypes, such as visual methods, periodontal probe transparency and cone-beam CT. Each method has its own characteristics. The gingival biotype is affected by a variety of factors, such as age, gender, crown shape, interdental papillary height, alveolar bone thickness and alveolar bone morphology. In the anterior region, different gingival biotype has different effects on oral aesthetics, and different gingival biotype also has different effects on the prognosis of periodontal, orthodontic and implant treatment. This article mainly reviews the influence of gingival biotype on the prognosis of oral treatment.
