Among the natural and synthetic materials investigated as bone graft substitutes, much interest has been focused on natural apatite obtained from low temperature heatdeproteinated compact bone. Previous research demonstrates that, when treated at a temperature below 500ยฐC, this material maintains it
## Abstract The flexural strength, microstructure and relative Ca and Si concentration at the surface of two commercial orthopedic aluminas were studied before and after aging up to 52 weeks in simulated body fluids or in subcutaneous implantation in rodents. There was no significant reduction in f
Heparin was covalently coupled to collageno-elastic grafts (CET) derived from lamb carotid arteries, by u s i n g t h e crosslinking agent 1-ethyl-3 (3-dimethylaminopropyl) carbodiimide (EDC). The collagenous grafts were pretreated with various aminating agents in order to enhance the number of avai
Numerous laboratory studies have been conducted in an effort to determine the susceptibility of dental alloys to tarnish and corrosion.'-8 These investigations have embodied a variety of storage media, storage times and the influence of variables such as the presence of dissimilar metals. However, t
The changes in mechanical properties and free radical concentration of curing Simplex P Radiopaque Bone Cement in vivo and in vitro conditions were studied. Samples were prepared so that each in vivo sample that cured and aged in the canine femoral intramedullary cavities had an in vitro counterpart
