Is Bioactive Glass A Ceramic

The present study aimed to evaluate the effect of a highly bioactive fully crystallized glass ceramic biosilicate of the system p 2 o 5 na 2 o cao sio 2 on various key parameters of in vitro osteogenesis.

Is bioactive glass a ceramic. Thus due to its biocompatibility and osteogenic capacity it came to be known as bioactive glass or bioglass. One is that such materials can be obtained in. The main bioactive glass and glass ceramic scaffo ld fabrication technologies followed by a discussion of scaffold microstructures developed e g por osity pore structure pore. Surface characterization was carried out by scanning electron microscopy and fourier transform infrared spectroscopy.

The high interest of bioactive glass ceramic materials in the biomedical field has been aroused by two interesting. Bioactive ceramics such as hydroxyapatite ha tricalcium phosphate tcp and certain compositions of silicate and phosphate glasses bioactive glasses and glass ceramics such as apatite wollastonite react with physiological fluids and through cellular activity form tenacious bonds to hard and in some cases soft tissue hench 1998. All these materials form an interfacial bond with adjacent tissue. Bioglass is a material using silica glass as the host material incorporated with calcium and phosphorous to fuse broken bones.

Bioactive glasses are a group of surface reactive glass ceramic biomaterials and include the original bioactive glass bioglass the biocompatibility and bioactivity of these glasses has led them to be investigated extensively for use as implant device in the human body to repair and replace diseased or damaged bones. Common bioactive materials available commercially for clinical use include 45s5 bioactive glass a w bioactive glass ceramic dense synthetic ha and bioactive composites such as a polyethylene ha mixture. This manuscript presents a first general appraisal of the scientific output in the interrelated areas of bioactive glasses and glass ceramics scaffolds implant coatings and tissue engineering. Nevertheless clinical applications as bone substitute or scaffold material are highly limited because of the often poor mechanical behavior of bioactive glasses.
