Supracrestal tissue attachment (STA) is a relatively new term that was introduced in 2017 following the World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions, co-sponsored by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP), which included expert participants from all over the world. It has replaced the term biological width, and refers to the junctional epithelium and supracrestal connective tissue. This article provides an updated review of the anatomy of STA, highlights the negative effects of violation and discusses its clinical relevance in restorative dentistry, including the use of crown lengthening. The impact of implants on STA is highlighted, and a summary of the relevance of STA in implant dentistry is also discussed.
CPD/Clinical Relevance: To allow dental practitioners to have more confidence providing adequate function, comfort, and aesthetics in the dentition, while maintaining periodontal health.
Article
In 1962, Cohen introduced the term ‘biological width’, which describes the biological attachment of the soft tissues to the root of the tooth and comprises the junctional epithelium and connective tissue attachment, and this being equivalent to the distance between the base of the gingival sulcus and the alveolar bone crest.1 This term was coined following the work by Gargiulo et al in 1961, in which the width is referred to as the dentogingival junction.2 The dentogingival junction can be divided into two components: the connective tissue attachment and the epithelial attachment.
The term ‘biological width’ was updated in 2017 at the World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions, to ‘supracrestal tissue attachment’ (STA), referring to the junctional epithelium and supracrestal connective tissue. The workshop was co-sponsored by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP) and included expert participants from all over the world. This article focuses on the clinical relevance of understanding the STA, particularly in the periodontal and restorative interface of dentistry.
