Effect of Composition and Sintering Temperature on the Structure and Properties of Porous Bioactive Glass Scaffolds
Calcium phosphate glasses have a potential use as bone substituting applications, because of their chemical composition is closely similar to that of natural bone. The implant glass can be slowly replaced by regenerating tissue and has good biocompatibility and non-toxicity. In this experimental stu...
