Tissue Response to the Implantation of Two New Machinable Calcium Phosphate Ceramics

The early histologic response to implantation of two newly developed machinable calcium phosphate ceramics was investigated. One of the materials is a machinable form of hydroxyapatite and the other a new machinable glass ceramic. One month following implantation, new bone had grown onto the surface of both implants. Further bone deposition and remodeling occurred during the ensuing 2 months. In the future, machinable qualities of these materials may make them extremely useful as implant materials.
