ABSTRACT:
The present invention provides for faster and stronger tissue-implant bonding by treating a ceramic implant with an ion beam to modify the surface of the ceramic. The surface modification can give the ceramic improved ion-exchange properties depending upon the particular ceramic and the type of ions used. In a preferred embodiment, a bioactive ceramic orthopaedic, dental, or soft tissue implant is bombarded with a beam of cations. When implanted in the body, the surface modification causes an increase in the release of critical ions, such as calcium or phosphorus, from the surface of the ceramic implant, and thereby accelerates implant-tissue bond formation.
