Periodontology Chapter 7: Understanding Gingival Recession and Mucogingival Defects

Any defect associated with deviation from normal anatomic/morphologic relationship between gingiva and alveolar mucosa

mucogingival deformities

features of periodontium influenced by genetic and environmental factors

biotype

slender, triangular shaped, narrow zone of keratinized tissue, greater tendency for onset progression of mucogingival defects

thin-scalloped

slender, triangular shaped, narrow-moderate zone of keratinized tissue, thick fibrotic gingiva

thick-scalloped

gingival wide square shaped, thick dense fibrotic tissue, wide band of keratinized tissue, more resilient

thick-flat gingival

movement of gingival margin to point apical to cementoenamel junction

gingival recession

what are some risk factors of gingival recession?

thin tissue bio type, narrow band of keratinized tissue, reduced thickness of alveolar bone, mechanical trauma
