PURPOSE The aim of this study was to evaluate the potential of an autologous bone marrow graft in preserving the alveolar ridges following tooth extraction. MATERIALS Thirteen patients requiring extractions of 30 upper anterior teeth were enrolled in this study. They were randomized into two groups: seven patients with 15 teeth to be extracted in the test(More)
The primary aim of this randomized clinical investigation was to evaluate gingival recession defects treated by a coronally advanced flap and sub-epithelial connective tissue graft (SCTG) with or without enamel matrix derivative (EMD). Twelve patients with Miller's class III buccal recession defects of ≥2.0 mm in similar contra lateral sites were included(More)
The aim of this study was to evaluate the potential of fresh frozen homologous and autogenous grafts, associated or not with autogenous bone marrow, to form bone. Sixty titanium cylinders were used, and were fixed to the skulls of 30 rabbits. These cylinders were filled with (A) autogenous bone (AM) autogenous bone associated with the bone marrow (H) fresh(More)
The aim of this study was to evaluate the efficacy of allogeneic block grafts impregnated with autologous bone marrow in horizontal ridge augmentation therapy. Ten patients with severe ridge volume deficiency in the anterior maxilla were treated with horizontal ridge augmentation. The patients were randomized into two groups: Five patients, using two(More)
It has been related in orthopedic surgeries the HLA sensitization. Thus, we evaluate if the use of fresh-frozen homologous bone (FFHB) for dental implant placement induce anti-HLA sensitization. Six patients were treated with FFHB corticocancellous block grafts. After 6 months, bone biopsies were harvested during implant placement to allow histomorphometric(More)
OBJECTIVES The aim of this study was to compare the bone healing observed after the use of (1) a scaffold enriched with fresh bone marrow, (2) a scaffold enriched with bone marrow mononuclear fraction, and (3) a scaffold alone. MATERIAL AND METHODS Twenty one rabbits were randomly divided into three groups of six animals and 1 group of 3 animals.(More)
Objective. The aim of this study was to evaluate the bone healing after the usage of a scaffold enriched with bone marrow. Study Design. Ten rabbits were divided into 2 groups of 5 animals. Bilateral 12 mm diameter defects were created in the parietal bones. In control group Bio-Oss were inserted in both defects and, in experimental group, Bio-Oss enriched(More)
This report describes a clinical case of severe Miller Class II gingival recession treated by two stages of surgery that combined a free gingival graft and connective tissue grafting. First, a free gingival graft (FGG) was performed to obtain an adequate keratinized tissue level. Three months later, a connective tissue graft (CTG) was performed to obtain(More)
PURPOSE To evaluate the regenerative results of the addition of bone marrow aspirate concentrate, using a single or double centrifugation protocol, to a xenogeneic bone graft in sinus floor elevation. MATERIALS AND METHODS Using a randomized, controlled pilot study design in 15 consecutive patients, sinus floor elevation procedures were performed with a(More)
PURPOSE This study investigated the combination of a bone marrow mononuclear fraction with a bone xenograft material in an appositional bone regeneration technique. MATERIALS AND METHODS Twelve New Zealand rabbits were randomly divided into two groups of six animals each. Bone reconstruction situations were created using titanium cylinders; these were(More)
