Chemical analyses of hydroxyapatite formation on SAM surfaces modified with COOH, NH2, CH3, and OH functions
Hydroxyapatite formation SAM surfaces Surface plasmon resonance
2010/11/29
Hydroxyapatite formation was examined at the surface of self-assembled monolayers (SAMs) modified with four functional groups, -COOH, -NH2, -CH3, and -OH. For COOH-SAM and NH2-SAM, scanning electron s...
Analysis of Chemical Interaction of 4-MET with Hydroxyapatite Using XPS
Adhesion 4-MET XPS
2009/9/15
Each dental adhesive contains a specific functional monomer that determines its actual adhesive performance to tooth tissue. 4-methacryloxyethyl trimellitic acid (4-MET) is well-known as one of the fu...
Role of Acidic Amino Acid for Regulating Hydroxyapatite Crystal Growth
Hydroxyapatite Crystal growth Acidic amino acid
2009/9/14
Non-collagenous proteins in hard tissue matrix are thought to play a pivotal role in regulating the crystal growth of hydroxyapatite (HAp). As most non-collagenous proteins are acidic proteins contain...
Effects of Sintering Temperature Over 1,300°C on the Physical and Compositional Properties of Porous Hydroxyapatite Foam
Porous hydroxyapatite Scaffold Synthetic bone substitute
2009/9/14
Porous hydroxyapatite (HAP) foam permits three-dimensional (3D) structure with fully interconnecting pores as well as excellent tissue response and good osteoconductivity. It is therefore thought to b...
Hydroxyapatite Film Coating by Thermally Induced Liquid-phase Deposition Method for Titanium Implants
Hydroxyapatite Liquid-phase deposition method Titanium implant
2009/9/14
Thermally induced liquid-phase deposition method was employed to produce a thin hydroxyapatite (HA) film on a titanium substrate in a metastable calcium phosphate solution. Titanium foil of 100×10×0.0...
Development of Cell-hybrid Artificial Bone: Effect of Osteogenic Differentiation of Bone Marrow Stromal Stem Cells on Bone Formation with Newly Developed Interconnected Porous Calcium Hydroxyapatite
Interconnected porous calcium hydroxyapatite Bone regeneration Cell-hybrid artificial bone
2009/9/14
The purpose of this study was to evaluate the effect of osteogenic differentiation of bone marrow stromal stem cells (BMSCs) on bone formation in a novel interconnected porous calcium hydroxyapatite (...
Hydroxyapatite coating by electrophoretic deposition at dynamic voltage
Hydroxyapatite coating Electrophoretic deposition Dynamic voltage
2009/9/11
The aim of this study was to evaluate hydroxyapatite (HA) coatings produced by dynamic voltage during electrophoretic deposition (EPD). Dynamic voltages from 0 to 200 V were incrementally applied in t...
Comparison of Osteogenic Potential Between Apatite-Coated Poly(Lactide-Co-Glycolide)/Hydroxyapatite Particulates and Bio-Oss®
Apatite coating Bio-Oss® Bone regeneration
2009/9/11
Previously, we developed a poly(lactide-co-glycolide)/nano-hydroxyapatite (PLGA/HA) composite that overcame the limitations of conventional ceramic bone substitutes. This was achieved by introducing a...
Bioactivity Evaluation of Synthetic Nanocrystalline Hydroxyapatite
Bioactivity Evaluation Synthetic Nanocrystalline Hydroxyapatite
2009/4/2
Background: Bone regeneration in the defects around oral implants using substitutes may improve
long-term prognosis of the implant. Hydroxyapatite (HA) is a good candidate for bone substitutes due ...
