    Abstract

    Two implantation sites were evaluated in the rabbit for measurement of the tensile strength of bonding between bone and both surface-reactive and metallic biomaterials. In rabbits, the tensile strength of bonding was 2.4 N/mm2 for glass-ceramic KG Cera rectangular solid implants that had been firmly clamped against cortical bone of the femur midshaft with champy plates for 56 days. The tensile strength of bonding was consistently less with cylindrical implants (flattened on one side) of the same material held against cortical bone of the femur midshaft with sutures or embedded into trabecular bone of the distal rabbit femur. The surface roughness of surface-reactive biomaterials affected the tensile strength of bonding only insignificantly.
