The purpose of this study was to evaluate the capability of silk fibroin (SF) and tricalcium phosphate-coated silk fibroin (SF-TCP) as a bone defect replacement matrix when grafted in calvarial bone defect of rats in vivo. Total 114 calvarial critical size defects (5.0 mm in diameter) made on 57 adult female Sprague-Dawley rats were used for this s...

... histological analysis, fixed samples were decalcified with 10% formic acid. After bisecting the samples tangential to the sagittal suture, they were paraffin-embedded with the cut surface facing outward, sectioned in 4 µm thicknesses, and stained with hematoxylin-eosin (H&E) and Masson's Trichrome (MT). Sections from each block nearest the center were selected for histological and histomorphometric evaluation (Fig ...

This study examines the effect of a hyaluronic acid (HyAc) containing tricalcium phosphate putty scaffold material (TCP-P) and of a particulate tricalcium phosphate (TCP-G) graft on bone formation, volume stability and osteogenic marker expression in biopsies sampled 6 months after bilateral sinus floor augmentation (SFA) in 7 patients applying a s...

Background: In the last decade, there are various methods of bone grafting in plastic surgery. Cancellous bone is more often used as bone graft than cortical bone due to its high osteoconductivity and osteogenic capability. The synthetic materials for bone graft such as tricalcium phospate (TCP) and hydroxy-apatite can be use as new alternative for...

There has been a resurgence of interest in alpha-tricalcium phosphate (α-TCP), with use in cements, polymer composites and in bi- and tri-phasic calcium phosphate bone grafts. The simplest and most established method for preparing α-TCP is the solid state reaction of monetite (CaHPO4) and calcium carbonate at high temperatures, followed by quenchin...

Objective To evaluate the bone repair associated with the use of biphasic ceramics based on hydroxyapatite and β-tricalcium phosphate (HA/TCP) in the procedures of maxillary sinus membrane elevation in human beings. Material and method Ten patients with a residual bone ridge in the posterior maxillary region between 3 mm and 5 mm in height were se...

To assess bone augmentation based on a non-critical defect, 1.5 mm deep cobalt-chromium (Co-Cr) barrier membranes were placed on seven adult California rabbits with three different grafting situations: whole blood, whole blood with tricalcium phosphate (TCP), and TCP mixed with bone marrow cells. Macroscopic assessment of the animals was performed...
