Filter by:Management of GR in the initial stages (when there is no inter proximal attachment and bone loss involved) has better clinical outcomes and reduces the chances of further progression of recession. Surgical treatment of recession involves techniques like pedicle grafts and free soft tissue grafts and their modifications. Sub epithelial connective tissue graft is considered as the gold standard in root coverage techniques. However this procedure involves a second surgical site increasing surgical time, complexity and patient morbidity. So there is a need of a technique which overcomes these limitations, is easier to perform and helps to achieve comparable root coverage with stable results over a long term. Novel overlapping rotated double (NORD) flap is a novel technique which offers a solution to this problem. This may help to achieve greater thickness of gingiva in the region of GR after healing and may reduce the risk of future recession. This technique is being compared with the bilaminar technique utilizing the sub epithelial connective tissue graft at the control sites, both the test and control groups will be treated using a microsurgical approach. If there is no significant difference in the root coverage achieved between the two techniques, this may reduce the need of harvesting connective tissue graft from a second surgical site. This technique is also expected to have better patient reported outcomes and will benefit the patients and operator both. This technique may also help to modify the phenotype of the affected tooth, thus making the results more stable.
This study aims to compare the de-epithelized gingival graft (control group) and modified combined approach for connective tissue graft (test group) in patients undergoing palatal graft harvesting for mucogingival surgery in the oral cavity
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.
Thin gingival phenotype is one of the major causative factors of gingival recession type 1 which can result in hypersensitivity, discomfort, and compromised esthetics. This study assess the efficacy of increasing the gingival thickness from thin gingival phenotype to thick gingival phenotype in the treatment of patients suffering from gingival recession (RT1) and maintenance of results using either connective tissue graft or de-epithelized free gingival graft after non-surgical periodontal debridement compared to non-surgical periodontal debridement alone.
Successful treatment of multiple gingival recessions (MRG) is a major challenge in periodontal plastic surgery due to complicated predisposing anatomical features of the surrounding tissues, such as a thin gingival phenotype or a limited zone of keratinized gingiva, variations in the depth and width of adjacent gingival recessions, shallow vestibulum and coronally inserted frenums and/or plica.The application of coronary advanced flap (CAF) or tunnel technique (TUN) with connective tissue graft (CTG) gives the best results in the therapy of MRG The application of connective tissue grafts in combination with various surgical techniques is accepted as the "gold standard" in GR therapy. A limitation in the application of CTG is the limited region of the donor site, especially in cases where a larger dimension of the CTG is required, or if the thickness of the hard palate tissue is inadequate. Techniques for obtaining subepithelial CTG (S-CTG), whether it is the trap-door technique or the single incision technique, are often associated with postoperative pain and discomfort, as well as necrosis/dehiscence of the palatal flap at the donor site. In order to overcome these limitations and obtain a firmer and more uniform CTG, especially when the thickness of the palatal tissue is inadequate (≤2.5 mm) and when a large dimension of the graft in the apico-coronary or mesio-distal direction is required, deepithelialization of the free gingival graft has been proposed (D-FGG). D-FGG has also been shown to be less prone to postoperative contraction, as it consists predominantly of collagen-rich connective tissue from the lamina propria, while adipose/glandular tissue is minimally represented. FGG can be deepithelialized intraorally with a diamond bur or diode laser, or extraorally with a scalpel. Despite all the biological advantages of D-FGG, there is scarce evidence in the literature about its histological characteristics after intraoral and extraoral deepithelialization, as well as the clinical outcomes of grafts thus obtained in combination with CAF in the treatment of MGR. Therefore, this aims of the study are to investigate the clinical efficacy and postoperative patient morbidity using D-FGG and modified CAF in the treatment of MGR, as well as to evaluate the histological characteristics of grafts obtained using two different deepithelialization techniques.
Included patients will be randomly allocated to the test (split-thickness non-advanced tunnel - Zabalegui et al. 1999) or to the control group (full-thickness coronally-advanced tunnel - MCAT - Aroca et al. 2010).
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.
Free gingival graft is a mucogingival surgical technique applied to increase keratinized gingival width and reduce gingival recession. Free gingival graft is one of the most widely used approaches in root closure treatments and in increasing the height of the keratinized gingiva. Evaluation of the effect of the amount of creeping attachment on the root surface caused by the free gingival grafts placed coronally and apical to the mucogingival line on the gingival recession in the mandibular anterior region with keratinized gingival deficiency with gingival recession. Forty patients with gingival recession and insufficient keratinized gingival height will be randomly divided into 2 main groups as free gingival grafts to be placed coronal and apical to the gingival recession.
: Interdental papilla deficiency leads to food impaction, problems with phonetics and an unaesthetic appearance. Reconstruction of the deficient papilla is therefore, important. The purpose of study is to compare the VCMX and SCTG in papillae reconstruction. The null hypothesis is that there is no significant difference in clinical outcome for interdental papilla regeneration by volume stable collagen matrix and subepithelial connective tissue graft.
Gingival recession is the migration of the gingiva to a point apical to the cemento-enamel junction. In order to treat challenging miller class 3 or RT2 recessions, several mucogingival approaches have been proposed. The subepithelial connective tissue graft (CTG) combined with a coronally advanced flap (CAF) has been considered as the "gold standard" for recession coverage around teeth. However, significant resorption of CT graft material has been reported if the graft material is exposed. And that can reduce the possibility of complete root coverage. volume stable collagen matrix - (VCMX ) is a volume stable, fully resorbable, porous, collagen matrix of porcine origin and spongious consistency and is one of the most biocompatible, novel material to be used in this study. VCMX of porcine origin is predominantly made of collagen type I and III and a small portion of elastin. VCMX is able to overcome the volume stability limitation of most commercially available grafts. The surgical technique proposed in a case series using a volume-stable collagen matrix and autogenous subepithelial CTG may be an effective method for periodontal biotype modification through thickening of the entire facial aspect for the treatment of gingival recession. VCMX consists of a single porous layer with interconnected pores (93% volume porosity) and an average pore size of 92 µm. While mechanical stability is achieved by chemical crosslinking, mechanical testing demonstrated preserved elasticity of the material over 14 days. Data have convincingly demonstrated enhanced promigratory and proadhesive properties of three primary cell types human oral fibroblas(hOFs) and human umblical vein endothelial cells(HUVECs), grown on the VCMX. The VCMX was characterized with an efficient adsorption of four recombinant growth factors (TGF-β, PDGF-BB, FGF-2, and GDF-5), naturally present in the blood clot. And in a RCT with Miller's class 1 and 2 it also showed that it provides volume stability and withstands early resorption, while encouraging formation of new soft tissue. Due to its wettability, suture-ability and biological properties, the device has been reported to become well integrated with surrounding soft tissue. No study has been evident on comparing VCMX and SCTG for Miller's class 3/RT2 recession defect. Therefore the purpose of the study is to compare the clinical outcome of VCMX ans SCTG in Miller's class 3/RT2 .
