Biological material is the most potential materials.Hydroxyapatite (Ca10(PO4)6(OH)2HA) is one of the most representative.It have excellent biocompatibility and the molecular structure and human body tissue highly similar. It is often used as bone repair and bone graft substitute materials and the surface coating of biomedical metal materials. In many of the metal materials, the titanium [...]
Titanium and its alloys have excellent mechanical strength, good corrosion resistance, and biocompatibility:being widely used for producing implants and biomedical devices, such as hip joint prosthesis, knee joint prosthesis, and dental implants. One factor that should be taken into account is the mismatch of Young’s modulus between bulk Ti-based metals (90-110 GPa) and bone (0.3-30 [...]
The composite material based on hydroxyapatite is a common material for bone repair. In this paper we prepared composites of nano-hydroxyapatite with siloxane modified (HA-g-Si) and siloxane. It is an Organic-inorganic hybrid nanocomposites which can be prepared by photopolymerization. The preparation and characterization were described in detail. Include the following parts:1. The hydroxyapatite with nano-crystalline [...]
Tissue engineering, an emerging multidisciplinary field to revolutionize the ways we improve the health and quality of life for people, promises the regrowth of adult tissue structure through the application of engineered cells and synthetic material. The scaffold used in tissue engineering provides the necessary support for cells to proliferate and maintain their differentiated function, [...]
Recently,a novel sol-gel technique which uses calcium nitrate tetrahydrate and phosphoric pentoxide as Ca and P precursors has been developed to prepare nano HA powder.Compared with other sol-gel processes, it is a simple way which does not require controlling pH value and long time. However,the reaction mechanism of this sol-gel process has not known.In this [...]
A non-woven beta-tricalcium phosphates（β-TCP）/collagen scaffold was fabricated by sol-gel electrospinning and impregnating methods. Firstly,raw calcium phosphates（CAP） powders were synthesized from triethyl phosphate（TEP） and calcium nitrate via sol-gel method.The effects of initial calcium/phosphate（Ca/P） molar ratio,catalyst and heat treatment temperature on the structural evolution of CaP were investigated by using X-ray diffraction（XRD）,infrared spectrometry（IR）, X-ray fluorescence spectroscopy（XRF）,and combined [...]
Tooth loss by various causes is a common disease in the dental field. Complete denture and removable partial denture are the main methods of the repair of tooth loss. As an integral part of the denture, denture base is used to repair soft tissue loss and to conduct and distribute Jaw force to the remaining [...]
Hydroxyapatite (HA), bearing similar ingredient and crystal structure with the main inorganic component of human hard tissue, demonstrates excellent bio-compatibility, bioactivity and osteoconductive properties.Porous structure is beneficial to nutrient diffusion, metabolite elimination, cell migration and bone ingrowth.The window between the interconnecting pores can act to allow osteoconduction through the porous structure. Unfortunately, the mechanical reliability [...]
The Preparation of Advanced Bioactive Glass and the Research of It in Wound Healing in Diabetic Rats
Presently the methods of preparation of bioactive glass have extended from the traditional melting method to the sol-gel method, hydrothermal method, template method and so on. In these methods we can obtain bioactive glass powder, mesoporous bioactive glass , bioactive glass fiber and other advanced bioactive glasses, which have some better biological properties, such as [...]
