The peri-implant soft tissue (PIS) augmentation procedure has become an integral part of implant-prosthetic rehabilitation. Minimal width of keratinized mucosa (KM) of 2 mm is deemed necessary to facilitate oral hygiene maintenance around the implant and provide hard and soft peri-implant tissue stability. PIS thickness of at least 2 mm is recommended to achieve the esthetic appearance and prevent recessions around implant prosthetic rehabilitation. The autogenous soft tissue grafts can be divided into two groups based on their histological composition—free gingival graft (FGG) and connective tissue graft (CTG). FGG graft is used mainly to increase the width of keratinized mucosa while CTG augment the thickness of PIS. Both grafts are harvested from the same anatomical region—the palate. Alternatively, they can be harvested from the maxillary tuberosity. Soft tissue grafts can be also harvested as pedicle grafts, in case when the soft tissue graft remains attached to the donor site by one side preserving the blood supply from the donor region. Clinically this will result in less shrinkage of the graft postoperatively, improving the outcome of the augmentation procedure. To bypass the drawback connected with FGG or CTG harvesting, substitutional soft tissue grafts have been developed.

“…After the partial-thickness flap has been prepared, the flap is sutured in a new apical position. Sutures must engage the flap and the rigid periosteal surface in order to stabilize the flap [60]. The FGG is stabilized on the exposed periosteal surface with sutures or cyanoacrylate [40,92].…”

BackgroundProlonged inflammation and oxidative stress can impede healing. To enhance healing efficiency, many solutions have been employed. This is an in vivo study comparing chlorhexidine (CHX) to a commercial antioxidant gel (AO).MethodsEnvelope flaps were created in the lower incisor gingival region of 60 Sprague–Dawley rats, and acellular dermal matrix (ADM) was inserted. Animals were randomly assigned to postsurgical treatment application of AO gel or 0.12% CHX twice daily. A control group received no postsurgical treatment. Data collected (before surgery, 24 h, and 72 h) included surgical images, tissue samples, and weights. Blinded scorers assessed images using a wound healing scale. Real‐time polymerase chain reaction (RT‐PCR) was used for gene expression of tumor necrosis factor‐alpha (TNFα), interleukin‐1 (IL‐1), myeloperoxidase (MPO), and superoxide dismutase (SOD).ResultsThe AO group scored higher than the CHX and control groups in clinical evaluation (p < 0.05). At 24 h, TNFα expression was upregulated in the AO group compared to CHX (p = 0.027) and controls (p = 0.018). The AO group had significantly higher expression of antioxidant enzyme (SOD) at 24 h compared to CHX (p = 0.021). All animals lost weight in the first 24 h. Animals treated with AO or CHX regained more weight at 72 h than control animals (p = 0.034 and 0.003, respectively).ConclusionAnimals treated with AO healed faster. AO led to earlier upregulation of TNFα and antioxidant enzyme SOD. We hypothesized that AO promoted an earlier inflammatory process while counteracting oxidative stress by increasing antioxidant responses via SOD.
