Abstract
A sintered tricalcium phosphate implant for filling bone cavities and for fixing bone fragments is provided, which comprises a discretely-shaped, porous body, at least one therapeutically-active ingredient impregnated into this porous body and distributed among the pores therein, and at least one coating of predetermined thickness of a biodegradable substance on at least a portion of this porous body, so that the time of absorption of the therapeutically-active ingredient is controlled by the thickness of the biodegradable substance. A process for producing this sintered tricalcium phosphate implant is also provided, along with an implant system for filling bone cavities and for fixing bone fragments in a living body, comprising a number of such tricalcium phosphate bone implants, with discrete coatings of biodegradable substance of predetermined thicknesses over at least some of the porous bodies constituting the tricalcium phosphate bone implants.
