What is the Biological Width?. The biological width is defined as the dimension of the soft tissue, which is attached to the portion of the tooth coronal to the crest of the alveolar bone. This term was based on the work of Gargiulo et al., who described the dimensions and relationship of the dentogingival junction in humans. Measurements made from the dentogingival components of 287 individual teeth from 30 autopsy specimens established that there is a definite proportional relationship between the alveolar crest, the connective tissue attachment, the epithelial attachment, and the sulcus depth..

They reported the following mean dimensions: A sulcus depth of 0.69 mm, an epithelial attachment of 0.97 mm, and a connective tissue attachment of 1.07 mm. Based on this work, the biologic width is commonly stated to be 2.04 mm, which represents the sum of the epithelial and connective tissue measurements 2 ..

WHO COINED THE TERM?. In 1977, Ingber et al. described “Biologic Width” and credited D.Walter Cohen for first coining the term 3 ..

WHAT IS THE NEW NAME- 2018 CLASSIFICATION?. Supracrestal Attachment OTHER NAMES: Area of Biological Width Also called as - Bermuda Triangle 4 or Devil’s Triangle 5 ..

Minimum biologic width advocated by various authors.

CONTRAVERSY!!!. Biological width is measured as a vertical dimension then why does it called as a biological WIDTH..
