“…To date, the most common clinical solution for large oral mucosa defects is the use of graft tissues obtained from the same patient or from tissue donors (de Souza et al, 2008;Kassab et al, 2010;Novaes et al, 2007;Paolantonio et al, 2002). This practice can be used instead of autologous graft techniques of palatal connective tissues (Langer and Langer, 1985), which may cause high morbidity for the patient and also may provoke a diminution in the available mucosa for further surgical procedures (Fujioka and Fujii, 1997).…”

In regenerative medicine, the generation of biocompatible substitutes of tissues by in vitro tissue engineering must fulfil certain requirements. In the case of human oral mucosa, the rheological properties of tissues deserve special attention because of their influence in the acoustics and biomechanics of voice production. This work is devoted to the rheological characterization of substitutes of the connective tissue of the human oral mucosa. Two substitutes, composed of fibrin and fibrin-agarose, were prepared in cell culture for periods in the range 1-21 days. The time evolution of the rheological properties of both substitutes was studied by two different experimental procedures: steady-state and oscillatory measurements. The former allows the plastic behaviour of the substitutes to be characterized by estimating their yield stress; the latter is employed to quantify their viscoelastic responses by obtaining the elastic (G') and viscous (G'') moduli. The results demonstrate that both substitutes are characterized by a predominant elastic response, in which G' (order 100 Pa) is roughly one order of magnitude larger than G'' (order 10 Pa). But the most relevant insight is the stability, throughout the 21 days of culture time, of the rheological quantities in the case of fibrin-agarose, whereas the fibrin substitute shows a significant hardening. This result provides evidence that the addition to fibrin of a small amount of agarose allows the rheological stability of the oral mucosa substitute to be maintained. This feature, together with its viscoelastic similitude with native tissues, makes this biomaterial appropriate for potential use as a scaffold in regenerative therapies of human oral mucosa.

“…Surgical treatment of gingival recession has been performed to improve esthetics, decrease root sensitivity, and eliminate the patients’ concerns about the loss of teeth. Various surgical techniques have been used, including free gingival/connective tissue/acellular dermal matrix grafting, various flap designs, combinations of grafting techniques and flap designs, and regenerative approaches 2‐9 . Although almost all of them produced statistically significant clinical improvements, different rates of success and predictability have been documented both between and within these procedures 2‐9 .…”

Systematic reviews assessing the best available evidence in the periodontal literature to detect significant differences in the effectiveness of different surgical techniques have revealed that subepithelial connective tissue grafts have the highest effectiveness and predictability in recession reduction 10‐12 .…”

Soft tissue grafting to improve implant esthetics

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received three soft tissue grafting procedures to augment the gingival tissue. The first surgery included a connective tissue graft to increase the width of the keratinized gingival tissue. The second surgery included the use of autografting (connective tissue graft) to coronally position the soft tissue and achieve implant coverage. The third and final surgery included the use of allografting material Alloderm to increase and mask the implant from showing through the gingiva. Healing period was uneventful for the patient. After three surgical procedures, it appears that soft tissue grafting has increased the width and height of the gingiva surrounding the implant. The accomplished thickness of gingival tissue appeared to mask the showing of implant threads through the gingival tissue and allowed for achieving the desired esthetic that the patient desired. The aim of the study is to present a clinical case with soft tissue grafting procedures.
