Bioceramics. Is there a difference?

Abstract

Bioceramics of aluminum oxide and calcium phosphate have a wide range of applications in orthopedic surgery. Each type of bioceramic is substantially different from the other, and variations exist within each type depending on the source and intended application. The physical, mechanical, chemical, and biologic properties are specific to each bioceramic. Significantly different tissue responses have been demonstrated among the various aluminum oxide, hydroxylapatite, and tricalcium phosphate bioceramics. Since the prospects for expanded clinical applications are excellent, the clinical community should become better acquainted with these types of biomaterials.
