ABSTRACT:
Although many materials have been used for osseous wound repair, no agent rrently available provides the surgeon with a predictable level of bone regeneration. Because they do not elicit elicit immunologic responses, and because of the disadvantages of obtaining donor bone, ceramic compositions such as phosphate-bonded alumina and similar ceramics have been investigated as possible bone substitutes capable of promoting bone growth. Since ceramic tricalcium phosphate is biodegradable it has been the subject of considerable research. Despite the research effort, the use of tricalcium phosphate ceramic materials in the regeneration of bone is still subject to improvement. A distinctive form of ceramic beta tricalcium phosphate, modified to augment bone regeneration is provided herein. It is readily implantable in a bone cavity to promote formation throughout the cavity of new bone to replace that lost through trauma, disease, respective surgery, and birth defects.
