Bioceramics consisting of calcium phosphate salts.

After a discussion of the chemical considerations involved in the production of calcium phosphate ceramics, animal and clinical studies are reviewed. Specific conclusions are that although these ceramics have high compressive strengths, they are not suitable for joint replacements. Prevention of alveolar ridge resorption is a promising concept, and space-filling and use of aids for jaw-bone enlargement are proposed for routine clinical application.
