Histomorphometric analysis of tricalcium phosphate ceramic implanted into Turkeys

Porous cylinders of tricalcium phosphate of two pore size distributions and four pore densities were implanted bilaterally into the ulnae of twelve skeletally mature turkeys. Morphometric analyses at two, four, and six post-operative months indicate implant resorption begins prior to the second post-operative month and that physical changes and biologic response continue at a rate dependent upon pore size distribution.
