What is the biological width?
The biologic width is patient specific and may vary anywhere from 0.75-4.3 mm. Based on the 1961 paper by Gargiulo, the mean biologic width was determined to be 2.04 mm, of which 1.07 mm is occupied by the connective tissue attachment and another approximate 0.97 mm is occupied by the junctional epithelium.
What is Supragingival plaque?
Supragingival plaque is bacteria adherent above the gingiva, whereas bacteria below the gingiva is called subgingival plaque. Growth in supragingival plaque mass results from nutrients obtained from ingested simple carbohydrates (glucose), lactic acid and other plaque components.

Advantages: Less distortion of crown margins, provides adequate bulk, good crown contours, can attain good esthetics.
Why is biologic width important?
The natural barrier that develops around the teeth and dental implants to protect the alveolar bone from disease and infection is known as the biologic width. As such, biologic width is vital for the preservation of periodontal health and removal of irritation that could damage the periodontium.
Where is Supragingival plaque formed?
