BACKGROUND Vertical releasing incisions might damage the blood supply to the flap and result in unesthetic visible white scars. The aim of the present study was to compare root coverage and esthetic outcomes of the coronally advanced flap (CAF) with and without vertical releasing incisions in the treatment of multiple gingival recessions. METHODS(More)
AIM To evaluate the clinical outcomes of the use of a xenogeneic collagen matrix (CM) in combination with the coronally advanced flap (CAF) in the treatment of localized recession defects. MATERIAL & METHODS In a multicentre single-blinded, randomized, controlled, split-mouth trial, 90 recessions (Miller I, II) in 45 patients received either CAF + CM or(More)
OBJECTIVES Complete root coverage is the primary objective to be accomplished when treating gingival recessions in patients with aesthetic demands. Furthermore, in order to satisfy patient demands fully, root coverage should be accomplished by soft tissue, the thickness and colour of which should not be distinguishable from those of adjacent soft tissue.(More)
OBJECTIVES To describe the differences in bone healing, when placing four different implant systems in fresh extraction sockets. MATERIAL AND METHODS Eight beagle dogs received implants randomly installed into the distal socket of three P3 and four P4. Four-implant systems were evaluated. Each animal provided four test implant sites. All animals were(More)
BACKGROUND Various modifications of the coronally displaced flap have been proposed in the literature with the attempt of treating gingival recession with uneven predictable results. The goal of the present study was to evaluate the effectiveness with respect to root coverage of a modification of the coronally advanced flap procedure for the treatment of(More)
AIMS The aim of this randomized-controlled clinical trial was to compare the patient morbidity and root coverage outcomes of a coronally advanced flap (CAF) with connective tissue (CTG) or de-epithelialized gingival (DGG) grafts. METHODS Fifty patients with one recession each were treated. In the control group, the CTG was harvested using the trap-door(More)
BACKGROUND Various clinical studies have demonstrated that applying commercially available enamel matrix proteins (EMP) on the instrumented root surface during access flap surgery promotes clinically significant gains of clinical attachment and bone in intrabony defects. The aim of the present controlled clinical trial was to evaluate the adjunctive effect(More)
BACKGROUND Several studies have documented the clinical efficacy of guided tissue regeneration (GTR) with non-resorbable expanded polytetrafluoroethylene (ePTFE) membranes and enamel matrix proteins (EMP) in the treatment of infrabony defects. The objective of this controlled clinical study was to compare the clinical outcomes of 3 surgical modalities in(More)
Complete root coverage is not always achievable, even in gingival recession with no loss of interproximal attachment and bone. The cemento-enamel junction is the most widely used referring parameter to evaluate root coverage results. The aim of the present study was to describe the most frequent diagnostic mistakes that may lead to incomplete root coverage(More)
BACKGROUND When multiple recession defects affecting adjacent teeth in esthetic areas of the mouth are present, patient-related considerations suggest the selection of surgical techniques that allow all gingival defects to be simultaneously corrected with the soft tissue close to the defects themselves. The aim of the present study was to evaluate, with(More)
