Filter by:Gingival thickness plays a key role not only in the etiology but also in the treatment of gingival recessions. a thin marginal tissue lining the hard periodontal tissues seems to be one of the main risk factor for the onset of gingival recession ; more recently, authors reported that as the gingival thickness decreases, the gingival recession severity increases . When gingival inflammation occurs, if the tissue is thin the consequent destruction can quickly produce a gingival recession (GR) . When treating a gingival recession, the clinician should aim not only to completely cover the exposed root surface but also to prevent a future recession recurrence Currently, CAF associated with graft is considered as the gold standard for exposed root coverage; this technique has demonstrated high rates in gingival recession reduction and positive predictability in obtaining complete root coverage . However, some disadvantages about this surgical approach can be easily highlighted: patients experience more discomfort, longer chair-time it's necessary and a second wound area is created . On the other hand, CAF procedure alone does not require a second surgical site, with better post-operative course, also reducing the surgical time. However, long term-studies report lower probability of complete root coverage when using the CAF technique without a simultaneous increase of the gingival thickness as compared to CAF+graft treatment. In this scenario, The Platelet rich fibrin (PRF) could be a valuable alternative treatment of gingival defects. It's a platelet concentrate, obtained by a fast and simple procedure that does not require anticoagulant and bovine thrombin . It can also be categorized as a live tissue thanks to platelets, leukocytes, growth factors and stem cells trapped in a polymerized fibrin mesh. PRF is used in various fields of regenerative medicine; It promotes stabilization and revascularization of the flaps, contributes to soft tissue wound healing and reduces post-operative discomfort. The purpose of this clinical study will be to determine if the combination of platelet rich fibrine membrane with a modified coronally advanced flap (MCAF) improved the gingival biotype compared to CAF + graft or CAF alone.
Perioteum in the recession defect site will be used as an autogenous graft after raising a flap and the results will be compared with another group which will be treated by the gold standard ( coronally advanced flap with subepithelial connective tissue graft).
patients with Miller class I , II gingival recession will be divided into 2 groups (control, intervention).the control one will receive coronally advanced flap with subepithililal connective tissue graft harvested from the palate while the intervention one will have coronally advanced flap with advanced platelet rich fibrin(A-PRF).as it represent a new generation of platelet concentrate allow for better healing and root coverage results. Null hypothesis: In patients with Miller class I and II gingival recession, there is no difference in amount of root coverage (mm) following the application of SCTG+A-PRF compared to CAF+SCTG.
This study evaluates postoperative morbidity of patients that undergo free gingival graft harvesting from palate with or without use of autogenous PRF (Platelet Rich Fibrin) membranes to cover the donor site.In the Test Group venous blood sampling was done in order to prepare PRF membranes used to cover the donor site, whereas in Control Group hemostatic agents with oxidized and regenerated cellulosa were used.
The present study is a human, prospective, single centre, single blind, comparative controlled randomized clinical trial for the treatment of Miller's Class I, II or combination of class I and II mandibular recession and comparing the clinical outcomes prior to and 6 months after treatment. The trial is in accordance to the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.
Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (CM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The CM has the advantage of no need of a second surgical area and availability overcoming the limitations of donor site in autograft. The aim of this study is to investigate the use of Mucoderm® in root coverage procedures combined with extended coronally positioned flap (ECAF), test group (TG), in comparison to the connective tissue graft associated with the ECAF, control group (CG).
The aim of this study is to evaluate clinically the results of two types of matrix (Geistlich Mucograft® and Mucoderm®) associated with CAF technique for the treatment of gingival recessions.
Gingival recessions are characterized by the apical migration of the marginal gingivae toward the cemento-enamel junction. Our team in France reported that 84,6% of the population exhibited gingival recession. Other epidemiologic data report that 25% of an american population exhibit recessions deeper than 3mm. Recessions may be associated with thermic or mecanic related pains and increased wear of the roots. It may causes aesthetic prejudice on smiling. It may also complicate prosthetic reconstruction when the volume of tissue are insufficient. A study on a Brazilian population reported that recessions negatively impacted the quality of life in terms of esthetics and root sensitivity. Many surgical procedures have been created to treat these recessions. Most of them include a gingival graft by mean of a sub-epithelial connective tissue graft. Usually it is harvested in the hard palate. However, the early healing of the palate may be associated with important pain and discomfort. Another harvesting site is the retromolar tuberosity. It seems to be of higher tissular quality and lower healing complications. However its limited volume prevent the harvesting of large graft. Almost no studies have compared the clinical outcome between palatal and tuberosity graft. A retrospective study of our team reported higher rate of complet root coverage with tuberosity graft versus palatal graft (OR=3,78 IC95%). After this observational study, our work introduce a interventional comparison between the two harvesting sites.
The objective of this randomized controlled clinical trial is to evaluate the increase of soft tissue thickness around single implants installed in maxillary esthetic area with the use of Leucocyte-Platelet rich Fibrin (L-PRF) membranes. The sample is of 42 individuals, where the control group (n = 21) will receive single implant placement only, while the test group will receive single implant placement with L-PRF membranes.
Several surgical techniques have been proposed to correct recession defect and attain root coverage. Though, the majority were executed on Miller Class I and II recession defects. Moreover, Analysis of literature revealed only a few studies that treated miller class III recession defects. In the current study, a new modification in the free gingival graft is proposed to provide the patient with more esthetic outcome, less pain and postoperative trauma. Likewise, the proposed graft modification will combined both FGG and CTG benefits, overcome the limitations of the FGG and enhances the advantages of CTG.
