Preparation of porous tri-calcium phosphate ceramic scaffold for bone tissue engineering
نویسندگان
چکیده
Calcium Phosphate ceramic has been widely used in bone tissue engineering due to its excellent biocompatibility and biodegradability. However, low mechanical properties and biodegradability limit their potential applications. In this project, hydroxyapatite (HA) and calcium phosphate bioglass were used to produce porous tri-calcium phosphate (TCP) bioceramic scaffolds. It was found that porous TCP bioceramic could be obtained when 20wt% bioglass addition and sintered in 1400C for 3 h. Significantly higher compressive strength (9.98 MPa) was achieved in the scaffolds as compared to those produced from TCP powder (<3 MPa). The biocompatibility of the scaffold was also estimated.

Improving the mechanical and bioactivity of hydroxyapatite porous scaffold ceramic with diopside/forstrite ceramic coating
Objective(s): Scaffolds are considered as biological substitutes in bone defects which improve and accelerate the healing process of surrounding tissue. In recent years a major challenge in biomaterials is to produce porous materials with properties similar to bone tissue. In this study, the natural bioactive hydroxyapatite scaffolds with nano Diopside /Forstrite coating was successfully synthe...
متن کاملDevelopment of an antibacterial porous scaffold for bone defect treatment
Background & Aim: The use of bone scaffolds is one of the new and efficient techniques for repairing bone defects that provide a suitable platform for cell proliferation and growth to repair the target tissue. One of the most important causes of failure of transplants and surgical procedures is the invasion of bacteria at the site of the complication and the development of severe infection. The...

BACKGROUND Calcium phosphate (CaP) ceramics are one of the most valuable biomaterials for uses as the bone scaffold owing to their outstanding biocompatability, bioactivity, and biodegradation nature. In particular, these materials with an open porous structure can stimulate bone ingrowth into their 3-dimensionally interconnected pores. However, the creation of pores in bulk materials would ine...

Calcium phosphate ceramic scaffolds have been widely investigated for bone tissue engineering due to their excellent biocompatibility and biodegradation. Unfortunately, they have the shortcoming of low mechanical properties. In order to provide strong, bioactive, and biodegradable scaffolds, a new approach of infiltrating the macro-tube ABS (acrylontrile butadiene styrene) templates with a hydr...
متن کاملNovel polymer-synthesized ceramic composite-based system for bone repair: an in vitro evaluation.
The emergence of synthetic bone repair scaffolds has been necessitated by the limitations of both autografts and allografts. Several candidate materials are available including degradable polymers and ceramics. However, these materials possess their own limitations that at least in part may be overcome by combining the two materials into a composite. Toward that end, a novel approach to forming...
