ABSTRACT
Background: Which are the different ways of stabilizing connective tissue grafts (CTGs) for root coverage and gingival augmentation by means of placement of sutures? There are various defined and undefined ways of stabilizing CTGs depending on experience and personal preferences. Most of the techniques profess use of absorbable sutures in separate interrupted fashion (sutures at the corners of the graft wherever possible). Aim: This paper describes a new suturing method, “the lingually-tied horizontal mattress contouring suture,” for stabilization of CTGs with or without epithelialized collar at the recipient site, for use with papilla retention and sparing techniques to treat marginal tissue recessions. Methods and Material: The suturing technique is described in detail. It can be indicated for good number of root coverage cases, with additional objectives of gingival augmentation, specifically developed for papilla sparing and papillary buccal de-epithelialization recipient site preparations. Results: Over a period of last 16 years this suturing technique showed promising results in terms of graft stabilization and survival. The main advantage of this technique lies in the use of cost-effective nonabsorbable sutures that usually retain some amount of tension on the soft tissues longer. Conclusion: The primary objective of the suturing technique, per se, is to stabilize the CTG firmly along the contours of the root surface and to expedite a very close adaptation to the interdental soft tissues as well. The secondary objective of the article or publication is to disseminate the knowledge acquired through long periods of performance and observation for the benefit of the periodontal community as whole. Further validation is advocated.
ABSTRACT
Gingival recession related to periodontal disease or developmental problems can result in root sensitivity, root caries, and esthetically unacceptable root exposures. In the past, multiple surgical procedures have been proposed to obtain root coverage on exposed buccal root surfaces. There has been great interest in the treatment of gingival recession defects, especially with subepithelial connective‑tissue grafting (SCTG). Recent advances have focused on SCTG by the tunnel technique. This article highlights the esthetic results obtained by adopting a modification of the tunnel technique using a single vertical incision along with autologous SCTG in the management of multiple adjacent Miller Class‑II gingival recessions. A single vertical incision was used along with tunnel preparation for the facile placement of SCTG into the prepared tunnel. After 6 months of follow‑up, the clinical condition was stable with satisfactory root coverage outcome. An excellent esthetical outcome was achieved and the patient was satisfied with the result.

This study aimed to measure the thickness of the epithelium and lamina propria of the palatal mucosa and to elucidate the location of the greater palatine artery to provide the anatomical basis for subepithelial connective tissue grafting. Thirty-two maxillary specimens, taken from the canine distal area to the first molar distal area, were embedded in paraffin and stained with hematoxylin-eosin. The thickness of the epithelium and lamina propria of the palatal mucosa was measured at three positions on these specimens, starting from 3 mm below the alveolar crest and in 3-mm intervals. The location of the greater palatine artery was evaluated by using image-processing software. The mean epithelial thickness decreased significantly in the posterior teeth; it was 0.41, 0.36, 0.32, and 0.30 mm in the canine, first premolar, second premolar, and first molar distal areas, respectively. The lamina propria was significantly thicker in the canine distal; it was 1.36, 1.08, 1.09, and 1.05 mm, respectively. The mean length from the alveolar crest to the greater palatine artery increased toward the posterior molar; it was 7.76, 9.21, 10.93, and 11.28 mm, respectively. The mean depth from the surface of the palatal mucosa to the greater palatine artery decreased from the canine distal to the first premolar distal but increased again toward the posterior molar; it was 3.97, 3.09, 3.58, and 5.50 mm, respectively. Detailed histological assessments of the lamina propria of the palatal mucosa and the greater palatine artery are expected to provide useful anatomical guidelines for subepithelial connective tissue grafting.
