## Abstract A piezoelectric ceramic has been investigated as a direct substitute for hard tissues. Barium titanate (BaTiO~3~) powder was slipcast and fired at 1430Β°C for 2 hr, then made piezoelectric by polarizing. After 16 and 86 days of implantation in the cortex of the femoral midshafts, the fem

## Abstract Glass ceramic implants containing 45% SiO~2~ with a Ca/P ration of 5 become firmly fixed to bone when placed in a cortical defect of an intact rat femur. The addition of fluoride ions to the implant prevents this fixation. The most significant difference between the two compositions is
Extensive acetabular defects produced surgically in 25 dogs were repaired using A-W glass-ceramic blocks. No dislocation of the femoral head, and no displacement or breakdown of the blocks was seen 1 year after surgery. All dogs were able to run normally shortly after surgery, except for one that li
