Is Bioactive Glass A Ceramic

Thus due to its biocompatibility and osteogenic capacity it came to be known as bioactive glass or bioglass.

Is bioactive glass a ceramic.

A bioactive glass ceramic of high mechanical strength ceramics metals and polymers coated with a bone like apatite bioactive bone cement and bioactive and ferromagnetic glass ceramic are only some examples of them. It mimics bone material and stimulates the regrowth of new bone material. 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.

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. Nevertheless clinical applications as bone substitute or scaffold material are highly limited because of the often poor mechanical behavior of bioactive glasses. 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. 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.

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.
