Single-stage crown lengthening and papilla reconstruction with a SCTG for subcrestal ECR in the esthetic zone

The joint workshop of the AAP (American Academy of Periodontology) and the EFP (European Federation of Periodontology) reaffirmed that positioning the restorative margin within the fibers of the supracrestal connective tissue attachment represents a significant risk factor for the development of periodontal complications. It is essential to recall that the supracrestal attachment shows considerable dimensional variability, both inter- and intra-patient, ranging from 0.2 to 6.73 mm. The relatively constant component is the connective attachment, averaging 1–1.5 mm; thus, the portion associated with the junctional epithelium shows the greater variability between the two. When a dental lesion presents a margin extending apically to the gingival sulcus, it is imperative to assess whether that margin lies within the junctional epithelium space, more…
