Background: Some types of implants used for orbital implantation have side effects and complications. In this study we have evaluated beta-tricalcium phosphate (ß-TCP: ChronOS) granules as an orbital implant. Methods: Eighteen rabbits randomly allocated to four groups. Right eye enucleation performed in groups I to III followed by filling with autologous bone particles (n=5), a mixture of autol...

OBJECTIVES The purpose of the present study was to evaluate bone healing in rabbit critical-sized calvarial defects using two different synthetic scaffold materials, solid biodegradable bioactive glass and tricalcium phosphate granules alongside solid and particulated autogenous bone grafts. MATERIAL AND METHODS Bilateral full thickness critical-sized calvarial defects were created in 15 New ...

The multi-sized porous β-tricalcium phosphate scaffolds were fabricated by freeze drying followed by slurry coating using a multi-sized porous sponge as a template. Then, gelatin was dip coated on the multi-sized porous β-tricalcium phosphate scaffolds under vacuum. The mechanical and biological properties of the fabricated scaffolds were evaluated and compared to the uniformly sized porous sca...

Bioactive glass-coated hierarchical porous tricalcium phosphate ceramics were constructed as both bone scaffolds and drug delivery devices to treat S. aureus -infected defects.

The purpose of this study was to investigate the crystallographic characteristics of 3 sets of plasma-sprayed hydroxyapatite (HA) coatings prepared with different degrees of crystallinity on Ti-6Al-4V substrates. X-ray diffraction analyses were performed on the coatings to determine mean percent crystallinity, calcium phosphate phases present, average crystallite size, and residual strain. The ...

The positive effect of silica on microstructural, mechanical and biological properties calcium phosphate scaffolds was investigated in this study. Scaffolds containing 3D interconnected spherical macropores with diameters the range 300–770 µm were prepared by polymer replica technique. Reinforcement achieved incorporating 5 to 20 wt % colloidal into initial hydroxyapatite (HA) powder. HA fully ...

The pH of the culture medium directly influences the growth of microorganisms and the chemical processes that they perform. The aim of this study was to assess the influence of the initial pH of the culture medium on the production of 11 low-molecular-weight organic acids and on the solubilization of calcium phosphate by bacteria in growth medium (NBRIP). The following strains isolated from cow...

The orthopedic foot and ankle surgeon needs bone grafts in the clinical situation of fracture healing and in bone-fusion procedures. This article briefly outlines thought processes and techniques for 2 recent options for the surgeon. The Trinity product is a unique combination of allograft bone and allograft stem cells. The beta-tricalcium phosphate and collagen materials provide an excellent s...

BACKGROUND The success of bone augmentation to a major degree depends on the biomechanics and biological conditions of the surrounding tissues. Therefore, an animal model is needed providing anatomical sites with similar mechanical pressures for comparing its influence on different biomaterials for bone regeneration. The present report describes the new bone formation associated to biomaterial ...
