Changes of Soft Tissue Grafting: A Randomized Study

Gingival Recession

To correct gum recession, patient's own tissue from the roof of the mouth is harvested and placed where there is root exposed. This is considered gold standard of treatment. Sometimes patient don't want to have second surgical site in their mouth and at the same time do not want to use alternative tissue from human or animal donor. Using patients' blood and preparing it as a membrane is the next best thing to correct gum recession.

Biofunctionalization of a Volume-stable Collagen Matrix (VCMX) for the Treatment of Single Gingival...

Gingival Recession

The treatment of single gingival recessions comprises different well-established techniques, and the association between coronally advanced flap (CAF) and the subepithelial connective tissue graft is considered the gold standard. However, despite the excellent clinical results obtained, the use of subepithelial connective tissue graft is related to an increased risk of trans and postoperative bleeding, a longer duration of the surgical procedure and greater postoperative pain and morbidity. To overcome these limitations and increase patient acceptance, new biomaterials have been developed as possible alternatives to the use of connective tissue graft. Recently, tissue engineering has been investigating collagen matrices as carriers of biologically active substances. In vitro and in vivo studies have shown that the biofunctionalization of these matrices using injectable platelet rich-fibrin (i-PRF) can optimize the healing process of soft tissues using own's patient regenerative components. However, although it has promising potential, clinical studies evaluating the performance of functionalized collagen matrices are still scarce in the literature. Thus, the present study aims to evaluate the clinical, esthetic, patient-centered, immuno and microbiological results of the use of the biofunctionalized volume stable collagen matrix (VCMX) for the treatment of single gingival recessions RT1. For such purpose, a randomized controlled clinical trial of superiority, parallel and blind will be carried out. Seventy-five patients with RT1 single gingival recession will be selected, who will be randomly allocated to one of the following groups: CAF+VCMX+i-PRF (n = 25), coronally advanced flap associated with VCMX functionalized with i-PRF; CAF+VCMX (n=25), coronally advanced flap associated with VCMX; and CAF group (n = 25), coronally advanced flap alone (CAF). The groups will be compared regarding clinical, esthetic and patient-centered outcomes at the baseline, three and six months after the surgical procedure. The microbiological evaluation will be performed at baseline, three and six months after surgery and the concentration of inflammatory markers and growth factors will be assessed before the procedure and 3, 7, 14, 30 and 60 days after treatment.

Timing Suture Removal on Root Coverage Procedures

Gingival RecessionSuture1 more

Gingival recession is defined as the displacement of the soft tissue margin apical to the cemento-enamel junction with exposure of the root surface. It affects a broad population with presence of periodontal disease as well as periodontally healthy individuals. The occurrence of gingival recessions is age-dependent and their development begins relatively early in life. For instance, gingival recessions were noticed in more than 60% of Norwegian 20-year-olds and in more than 90% of the older population. Similar findings were reported in Brazilian and French population. In populations deprived of dental care, the occurrence of gingival recessions was even higher. Many factors have been implicated in the etiology of gingival recession, including plaque, position of the tooth in the arch and improper toothbrushing. It is difficult to see a single cause for the development of labial gingival recession. It has been demonstrated in several investigations that if left untreated, the probability of progression of the recession is high even with good oral hygiene. The indications for treatment of gingival recession are: esthetics, dental hypersensitivity, and the prevention of caries as well as further progression of the recession. Therapeutic options for recessions have been well documented with a high degree of success. Their ultimate goal is the location of the gingival margin coronal to the CEJ, with minimal probing depth and a pleasant soft tissue integration with the adjacent teeth. With such a prevalent condition, it becomes critical to discriminate when to treat these lesions and which are the anatomical and surgical characteristics that are going to determine the amount of root coverage. Regarding surgical characteristics, it has been demonstrated that the accomplishment of complete root coverage may be prejudiced by the post-surgical position of the gingival margin (the more coronal to the CEJ the greater the chance to achieve root coverage). The same author conducted a randomized clinical trial showing that the higher the flap tension, the lower the recession reduction. Another surgical factor affecting root coverage may be the use of microsurgical approaches by the use of smaller diameter sutures. According to a recently published systematic review, early suture removal (less than 10 days) can negatively affect root coverage outcome. The healing process after pedicle graft was investigated in an animal model study. The healing was divided into four different stages, the adaption stage (0-4 days), the proliferation stage (4-21 days), the attachment stage (27-28 days) and the maturation stage (1-6 months). During the proliferation stage, connective tissue invades the fibrin layer from the basal level of the flap, and after 6-10 days a layer of fibroblasts is seen in apposition to the root surface. These cells are believed to differentiate into cementoblasts at a later stage of healing. At the end of the proliferation stage, thin collagen fibers are formed adjacent to the root surface, but a fibrous union between the connective tissue and the root has not been observed. It seems logical that stabilizing the flap with sutures for a prolonged period of time during the proliferation phase would help maintain the gingival margin on a more coronal position postoperatively. On the other hand, the longer the sutures remain postoperatively, the greater the chances of plaque accumulation and inflammation affecting negatively to root coverage. The systematic review by Tatakis and Chambrone included 17 randomized clinical trials that provided an overall data of 325 single recession defects that were treated by coronally advanced flap. While they investigated time of suture removal, the studies included in this study did not account for this variable, thus leading to some bias. Moreover, different suture materials, type of suturing technique may also play an important role in the healing process. Therefore, the aim of this study is to evaluate the clinical outcome of timing suture removal regarding root coverage on coronally advanced flap.

Xenogenic Collagen Matrix for the Treatment of Multiple Gingival Recessions

Gingival RecessionGeneralized

The primary aim of this study is to evaluate whether the use of a xenogenic collagen matrix (XCM) for the treatment of multiple adjacent gingival recessions (MAGRs) with a multiple coronally advanced flap technique (mCAF) achieves better results than the use of an autologous connective tissue graft (CTG) in terms of recession reduction (primary outcome) and other secondary root coverage outcomes (e.g. complete root coverage, mean root coverage). Moreover, this study aims to compare secondary clinical variables (e.g. keratinized tissue width (KTW) changes, probing pocket depth (PPD) changes, volumetric gain (VG), etc.), also with a digital approach, the patient-reported outcome measures (PROMs e.g. pain, swelling, bleeding). The hypothesis of this study is that at 6 months and 1 year follow-up the mCAF with XCM is not inferior to CTG in terms of recessions reduction and secondary clinical variables, and superior regarding to PROMs.

Gingival RecessionLack of Keratinized Gingiva

This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva. The SAMRI technique described is a novel technique involving a simplified incision and suturing technique and to the investigators' knowledge, this is the first study that seeks to compare this technique to other techniques for differences in clinical outcomes (percentage root coverage, resultant tissue thickness, and width of keratinized tissue) and patient-centered outcomes (post-operative pain, swelling, changes in daily activities, and patient-assessed esthetics) in a controlled study.

Gingival RecessionLocalized1 more

Gingival recessions (GR) are often associated with non-carious cervical lesions (NCCL), resulting, thus, in a combined defect. This mucogingival condition has a different treatment prognosis when compared with a GR without wearing surface associated and frequently requires a surgical-restorative approach to achieve better esthetics and functional results. A limited number of clinical studies assessed different multidisciplinary protocols for the management of single combined defects and there is evidence that the use of dental materials does not harm the periodontal tissues and does not influence the root coverage obtained by means of subepithelial connective tissue graft (CTG). Although the association between coronally advanced flap (CAF) and CTG provides more predictable and stable outcomes in the long term, its use is related to some drawbacks. Different biomaterials have been developed to overcome these limitations as a possible alternative to autogenous graft. However, despite its potential, there is a lack of studies evaluating its use in treating this type of condition. Thus, this study aims to assess from a clinical and esthetics point of view and patient-centered outcomes, the use of a new collagen matrix (Geistlich Fibro-Gide®) associated with CAF for the management of single combined defects. For such purpose, 50 patients with single RT1 gingival recessions associated with NCCL will be enrolled and randomly allocated to one of the following groups: control group (n=25), partial restoration of cervical lesion and coronally advanced flap for root coverage (PR+CAF) and test group (n=25), partial restoration of cervical lesion and coronally advanced flap associated with volume stable collagen matrix (PR+CAF+VCMX). The two groups will be compared regarding the clinical parameters, among which bleeding on probing (BOP), biofilm accumulation (IP), clinical attachment level (CAL), recession reduction (RecRed), and the percentage of combined defect coverage (%CDC). Patient-reported outcomes such as post-surgery pain and discomfort, time to recover, the decrease of dentin hypersensitive, and aesthetics will be gathered. A professional assessment will be carried out regarding the aesthetic parameters. All these evaluations will be performed at the baseline and three and six months postoperatively.
