Abstract
The subepithelial connective tissue graft (SCTG) is a predictable technique for root coverage. The small number of potential postoperative problems make SCTG the current treatment of choice for reversing gingival recession.The purpose of this article is to report three cases of complications after the use of an SCTG where an abscess occurred following the initial healing phase. The surgical technique that was used and the treatment that was provided for the abscesses are reported, and the possible causes of these complications are discussed.The abscesses were treated conservatively, and no recurrence has been observed after treatment.Possible causes of the abscesses include "stitch abscess" or reaction to the suture material used for the submerged sutures, or a possible role of epithelium implanted during the procedure. The clinical outcome of the root coverage procedure was not affected.
