Subepithelial Connective Tissue Graft Technique for Root Coverage

TLDR

The success of subepithelial connective tissue grafts for root coverage is attributed to the double‑blood supply at the recipient site from the underlying connective tissue base and the overlying recipient flap. This article describes the use of the subepithelial connective tissue graft as a donor source for root coverage. Four cases illustrate the versatility of the procedure for single or multiple root coverage in the maxillary arch, covering existing crown margins, and combining ridge augmentation with root coverage. Across 56 cases over four years, the technique achieved 2–6 mm of root coverage with minimal sulcus depth, no recession recurrence, and a closed donor site that produced less postoperative discomfort.

Abstract

This article describes the use of the subepithelial connective tissue graft as a donor source for root coverage. The success of these grafts has been attributed to the double-blood supply at the recipient site from the underlying connective tissue base and the overlying recipient flap. Four cases have been illustrated to demonstrate the versatility of this procedure for areas of single or multiple root coverage especially in the maxillary arch, coverage of existing crown margins and areas requiring a combination of ridge augmentation and root coverage. An increase of 2 to 6 mm of root coverage has been achieved in 56 cases over 4 years with minimal sulcus depth and no recurrence of recession. The donor site is a closed wound which produces less postoperative discomfort.
