Ideally, bioactive ceramics for use in alveolar ridge augmentation should possess the ability to activate bone formation and, thus, cause the differentiation of osteoprogenitor cells into osteoblasts at their surfaces. Therefore, in order to evaluate the osteogenic potential of novel bone substitute materials, it is important to examine their effect on osteoblastic differentiation. This study e...

The effects of hydroxyapatite (HA)-coating onto collagen carriers for application of recombinant human bone morphogenetic protein 2 (rhBMP-2) on cell differentiation in vitro, and on in vivo healing patterns after sinus-augmentation and alveolar socket-grafting were evaluated. In vitro induction of osteogenic/adipogenic differentiation was compared between the culture media with rhBMP-2 solutio...

Autologous bone grafts for alveolar ridge augmentation are the gold standard for restoring atrophic residual ridges in preprosthetic surgery. Many indications, donor sites, and techniques have been reported. The purpose of this article is to review the anatomy, surgical technique, and potential complications associated with proximal tibia bone harvest. A consecutive series of 44 patients who un...

Systematic review conclusion: Lateral ridge augmentation procedures are effective in treating deficient alveolar ridges prior or simultaneously to the placement of dental implants. For the simultaneous approach, the combination of bone replacement grafts and barrier membranes was associated with superior outcomes. For the staged approach, the combination of bone blocks, particulate grafts, and ...

AIM The aim of this study was to evaluate the healing of autologous bone block grafts or deproteinized bovine bone mineral (DBBM) block grafts applied concomitantly with collagen membranes for horizontal alveolar ridge augmentation. MATERIAL AND METHODS In six Labrador dogs, molars were extracted bilaterally, the buccal bony wall was removed, and a buccal box-shaped defect created. After 3 mo...

INTRODUCTION To determine the esthetic outcome of implant-based reconstructions after autologous and allogeneic bone grafting. METHODS From 2003 to 2009, 67 patients underwent alveolar ridge augmentation and were enrolled in the study, 41 meet the inclusion criteria and 31 agreed to take part in the study. Patients were 18-69 years old (mean: 49.3 ± 13.8 years), and predominantly female. Pati...

Objective: to investigate the predictive factors of failure in bone grafts for alveolar ridge augmentation and implant surgery. Methods: we reviewed the charts of 166 patients operated between 1995 and 2014. A total of 248 grafting procedures were performed. We submitted the data to the binomial test at 5% significance. Results: grafts to gain width of the alveolar ridge (65.32%) were more freq...

Platelet-rich fibrin, developed in France by Choukroun et al., is a second generation platelet concentrate widely used to accelerate soft and hard tissue healing. It is a strictly autologous fibrin matrix containing a large quantity of platelet and leukocyte cytokines. It has also been shown to stimulate the growth of osteoblasts and periodontal ligament cells, both of which are significant for...

INTRODUCTION The main problems of autogenous bone transplants are their unpredictable atrophy and their loss of structure. One key factor lies in the poor revascularization of simple onlay grafts. The the aim of this study was to evaluate the revascularization processes in autogenous bone grafts from the iliac crest to the alveolar ridge. METHODS In a sheep model, autogenous bone grafts were ...
