What is the minimum acceptable biological width in dental restorations?

The minimum acceptable biological width in dental restorations is indeed 2mm. Biological width refers to the distance from the epithelial attachment to the crest of the alveolar bone and includes the junctional epithelium and the connective tissue attachment.

Maintaining at least 2mm of biological width is crucial when placing restorations, especially in areas near the gingiva, to prevent periodontal issues and ensure the longevity of the restoration. Violating this space can lead to inflammation, the formation of periodontal pockets, and ultimately the loss of supporting bone, which can jeopardize both the restoration and the health of the surrounding tissues.

Understanding the significance of biological width is essential for successful periodontal and restorative dentistry practices.
