Active clinical trials for "Gingival Recession"

The aim of the study is to evaluate the effect of feather edge finish line and deep chamfer finish line on gingival position, bleeding on probing and marginal adaptation.

This study evaluates the 4 different techniques used in clinical measurement of gingival phenotype. 1) Tranclusency of UNC-15 Periodontal Probe, 2) Transgingival probing with Endodontic file (#20), 3)Transgingival Probing with Modified Florida Probe and 4) Translucency Colorvue Biotype Probe. The aim of our study is to evaluate the reliability and applicability of the current examination methods recommended in order to improve the deficiencies of the traditional examination methods used in the evaluation of the gingival phenotype.

This study will compare a new technique of free gingival graft to the original one, in order to evaluate the stability of the graft volume over one year and other variables. Twenty patients will receive the original technique of free gingival graft (controls) and twenty patients will receive the modified technique, in which the free gingival graft is submerged (tests), at the inferior incisors area.

Limitation of donor site and significant postoperative morbidity are often described in connective tissue graft harvesting. We want to show if mucoderm used in tunnel technique to recover miller class I and II recessions defects could be an alternative to connective tissue graft.

VISTA technique with PRF compared to MCAF technique with PRF to treat gingival recession

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).

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.

This clinical study consists on taking 2 different records of the upper and lower incisors area : 1) a perpendicular x-ray and 2) an ultrasonic measurement of gingival thickness on the labial plate. Both measurements are used in order to measure gingival and bone thickness. The aim was to verify the reliability of the tissue measurements of an ultrasonic technique compared with the radiographic technique and to verify whether the biotype has correlation between the maxillary and mandibular biotype in the same patient.

A novel minimally invasive guided creeping technique (GCT) is suggested to treat gingival recessions.

Management of Miller class I & II gingival recession using coronally advanced flap combined with conventional de-epithelialized free gingival graft versus coronally advanced flap combined with abrasive de-epithelized connective tissue graft Null hypothesis: In patients with Miller class I and II gingival recession, there is no difference between coronally advanced flap with conventional de-epithelialized free gingival graft and coronally advanced flap with abrasive de-epithelized connective tissue graft in recession depth reduction.
